AATB Accreditation, Federal Compliance, and the State-by-State Legal Landscape for Stem Cell Biologics in 2026

By Stem Nova Network · Updated March 2026 · Regulatory Reference · For Licensed Medical Professionals Only · Not Legal Advice

As the regenerative biologics market grows, licensed practitioners are asking two questions more frequently than ever: what does AATB accreditation actually mean, and what does the law say in my state about stem cell biologics? This guide answers both — covering the federal regulatory baseline, what AATB accreditation requires and why it matters for sourcing decisions, compliant vs. non-compliant marketing language, and the current legislative landscape across the states most active in this space as of early 2026.

This is a regulatory reference for licensed practitioners. It does not constitute legal advice. Practitioners should consult qualified legal counsel for guidance specific to their practice, jurisdiction, and the products they are sourcing or using.

⚠ Important Regulatory Baseline There are currently no FDA-approved exosome or UCT-MSC stem cell products for any therapeutic indication in the United States. State laws described in this article operate alongside — not in place of — federal law. Federal enforcement authority remains active regardless of state-level legislation.

Part 1: The Federal Regulatory Baseline

21 CFR Part 1271 — The HCT/P Framework

At the federal level, human cell, tissue, and cellular and tissue-based products (HCT/Ps) — including umbilical cord tissue-derived mesenchymal stem cells (UCT-MSCs) and exosome biologics — are regulated under 21 CFR Part 1271. This framework governs how these products are manufactured, tested, stored, and distributed.

Under the Section 361 pathway, certain HCT/Ps may be exempt from premarket FDA approval if they are minimally manipulated, intended for homologous use, not combined with a drug or device, and do not have a systemic effect dependent on the metabolic activity of living cells. Products that do not meet all of these criteria require premarket review — including an Investigational New Drug (IND) application or Biologics License Application (BLA).

FDA's Position on Exosomes — As of Early 2026 The FDA has issued multiple warning letters to exosome suppliers for marketing products as treatments for disease conditions without required regulatory authorization. No exosome product holds FDA approval for any therapeutic use. The only safe lane for exosome biologics under current federal law is topical cosmetic application with no disease claims.

What Federal Law Requires from Manufacturers

  • FDA establishment registration — tissue establishments must be registered with the FDA as HCT/P manufacturers
  • Current Good Tissue Practice (cGTP) — manufacturing must comply with cGTP standards under 21 CFR Part 1271 (not cGMP, which applies to pharmaceutical drugs)
  • Donor eligibility determination — full donor screening including infectious disease testing per 21 CFR Part 1271 Subpart C
  • Lot-specific testing and traceability — sterility, endotoxin, mycoplasma, and identity markers documented per lot
  • Adverse event reporting — manufacturers must report adverse reactions potentially related to their HCT/P products

Part 2: What AATB Accreditation Means

What AATB Is

The American Association of Tissue Banks (AATB) is a nonprofit professional organization that establishes voluntary accreditation standards for tissue banks and tissue establishments. AATB has developed comprehensive standards for donor screening, tissue processing, packaging, labeling, storage, and distribution that go beyond the minimum FDA regulatory requirements.

AATB accreditation is not a government certification — it is a rigorous voluntary quality standard that requires a facility to undergo regular independent inspection and demonstrate compliance with AATB's published standards across every aspect of its operations.

What the Accreditation Process Requires

  • Donor screening and eligibility — comprehensive review of donor medical history, social behavior history, physical assessment, and relevant lab testing
  • Infectious disease testing — mandatory testing for a defined panel of communicable disease agents per AATB standards
  • Processing and manufacturing controls — validated SOPs, environmental monitoring, equipment qualification, and process controls
  • Quality management system — documented QMS including deviation management, CAPA processes, and change control
  • Storage and distribution — validated cold-chain procedures, shipping qualification, and chain of custody documentation
  • Inspection and ongoing surveillance — facilities must pass AATB on-site inspections and maintain compliance to retain accreditation
AATB vs. FDA Registration — Key Distinction FDA establishment registration confirms that a facility has notified the FDA of its existence as an HCT/P manufacturer. It does not involve inspection or quality review. AATB accreditation requires on-site inspection and demonstrated compliance with comprehensive quality standards. Both are important — but they are not equivalent signals of quality. Florida SB 1768 and the pending Arizona SB 1214 both explicitly name AATB as a required accrediting body for supplier sourcing.

Part 3: Compliant vs. Non-Compliant Marketing Language

Even in states with active stem cell legislation, the language practitioners use to describe these products to patients and in marketing materials is heavily scrutinized by the FDA and FTC. The following guidance applies regardless of which state you practice in.

Exosome Biologics — Topical Cosmetic Use Only

❌ Never Use

  • Treats inflammation / anti-inflammatory
  • Regenerates tissue / promotes healing
  • Activates stem cells
  • Injectable-grade
  • FDA compliant / FDA approved
  • Proven to improve [condition]
  • Repairs / restores / reverses
  • Any disease name (arthritis, hair loss, wound healing, neuropathy)
  • Better outcomes / superior results

✅ Compliant Language

  • For topical cosmetic use only
  • Not for injection or therapeutic use
  • Not FDA-approved
  • Biological signaling profile
  • Cellular uptake characteristics
  • Post-procedure topical support
  • Visible radiance / the look of skin texture
  • NTA-verified particle count
  • For use by licensed professionals only

UCT-MSC Stem Cells — For States with Active Legislation

❌ Never Use

  • FDA approved / FDA legal in this state
  • Proven to treat [condition]
  • Cures / heals / reverses disease
  • Better outcomes than standard care
  • Legal alternative to surgery
  • Disease names in promotional materials
  • Safe and effective (implies FDA approval)

✅ Compliant Language

  • Performed by a licensed physician subject to applicable state and federal requirements
  • Not approved by the U.S. Food and Drug Administration
  • Patients should consult their primary care provider
  • For physician evaluation only
  • Investigational — individual results may vary
  • Sourced from AATB-accredited, FDA-registered tissue establishment
  • cGTP-compliant per 21 CFR Part 1271
The Net Impression Test The FDA and FTC evaluate the overall impression of marketing — not just individual claims in isolation. Read your marketing copy and ask: could a reasonable person interpret this as a claim that the product treats a disease or condition? If yes, revise before publishing. This applies to your website, social media, email campaigns, in-office materials, and any patient-facing content.

Part 4: State-by-State Legal Landscape

Several states have enacted legislation creating pathways for licensed physicians to use non-FDA-approved stem cell biologics under defined conditions. This section covers all active, disclosure-only, and pending states as of early March 2026. State laws govern the practice of medicine within a state — they do not override FDA's authority over the products themselves.

Florida — SB 1768 Active July 1, 2025

Florida's SB 1768 (codified as Florida Statute § 458.3245) is the most significant and well-structured state stem cell law in the country. It authorizes licensed MDs and DOs to perform non-FDA-approved stem cell therapy under clearly defined conditions.

  • Who can administer: Licensed physicians only — MDs (Chapter 458) and DOs (Chapter 459)
  • Covered indications: Orthopedics, wound care, and pain management only
  • Cell sources permitted: Adult-derived stem cells from human tissue including birth tissue. Embryonic, fetal, and adipose-derived tissue explicitly excluded.
  • Supplier requirements: Products must come from FDA-registered facilities accredited by AATB or other listed organizations. Manufacturing must comply with 21 CFR Part 1271.
  • Required advertising notice: All advertising must include a statutory disclosure that the physician performs stem cell therapies not yet approved by the FDA.
  • Exosomes: Not explicitly covered. Practitioners should consult legal counsel before administering exosome biologics under SB 1768.

SNN relevance: Stem Nova Network's supplier is AATB-accredited, FDA-registered, and cGTP-compliant per 21 CFR Part 1271 — meeting SB 1768's sourcing requirements for covered stem cell products.

Texas — HB 810 (Charlie's Law) + HB 5147 Active Sept 2017 / Updated Sept 2025

Texas was one of the first states to create a legislative pathway for investigational stem cell therapy, building on its Right to Try framework. HB 810 extended Right to Try access — originally for terminal patients — to patients with severe chronic illness for adult stem cell biologics specifically.

  • Right to Try connection: Texas passed its state Right to Try law in 2015 for terminal patients. HB 810 extended that framework to patients with severe chronic illness for adult stem cell biologics — a separate, stem-cell-specific access pathway.
  • Who can administer: Licensed physicians at a hospital, medical school, or registered outpatient facility (outpatient added by HB 5147) with IRB oversight
  • Eligible patients: Patients with severe chronic disease or terminal illness
  • Clinical trial requirement: The stem cell treatment must have been tested on humans in a clinical trial (not required to be a U.S. trial)
  • 2025 update (HB 5147): Expanded to outpatient settings with physician registration. IRBs now submit annual adverse event reports to the Texas Medical Board.
Utah — SB 199 Active May 1, 2024

Utah's SB 199 is the broadest state stem cell access law currently in effect, allowing administration of placental and perinatal stem cell therapies by a wide range of licensed providers with patient disclosure — but without the supplier quality standards Florida requires.

  • Who can administer: Any licensed healthcare provider whose scope includes stem cell therapy — physicians, naturopaths, chiropractors, nurses, midwives
  • Requirements: Disclosure to patients and signed informed consent. No clinical trial requirement. No mandatory supplier accreditation standards.
  • Federal conflict: Utah SB 199 explicitly permits therapies the FDA considers to require premarket approval. Practitioners should consult legal counsel before relying on this law.
California — SB 512 Active — Disclosure Only

California's SB 512 is a consumer protection and disclosure law — not a treatment authorization. California's Medical Board has actively warned practitioners against administering unapproved stem cell products. The only legal path for exosome or stem cell therapy use in California is within a formal FDA-approved IND clinical trial.

  • Required notice (exact statutory language): "THIS NOTICE MUST BE PROVIDED TO YOU UNDER CALIFORNIA LAW. This health care practitioner performs one or more stem cell therapies that have not yet been approved by the United States Food and Drug Administration. You are encouraged to consult with your primary care physician prior to undergoing a stem cell therapy."
  • Where it must appear: Posted prominently at office entrance, in patient-visible areas, included in all advertising, and provided in writing to the patient before initial treatment
  • Enforcement: $1,000 fine per violation after the first violation
  • Practical guidance: California is not a treatment-authorization state. SB 512 governs how practitioners must communicate — it does not create a green light for administering unapproved products.
Nevada — 2023 Biologics Law + SB 128 Active / Updated Jan 1, 2026

Nevada has two separate pieces of legislation relevant to regenerative biologics, representing one of the more permissive state environments — though with significant federal conflict concerns.

  • 2023 biologics law: Allows licensed providers to offer non-FDA-approved biologics including allogeneic cellular material as "individualized investigational treatments." Broad language with no IRB or clinical trial requirement. Creates significant state-federal enforcement tension — practitioners should consult legal counsel before relying on this law.
  • SB 128 — effective January 1, 2026: A provider disclosure law requiring licensed physicians, PAs, APRNs, and DOs to discuss stem cell therapy options with patients diagnosed with conditions like arthritis. This is a discussion mandate — not a treatment authorization.
Vermont — Act 61 Active — Disclosure Only

Vermont's Act 61 is a consumer protection and informed consent law — not a treatment authorization. Practitioners administering non-FDA-approved stem cell products in Vermont must post required notices at the office entrance and in patient-visible areas, include the notice in all advertising, and obtain a signed disclosure form from patients before each administration. A copy must be retained in the medical record.

Montana & New Hampshire Right to Try Expansions

Montana (SB 535) and New Hampshire (HB 1292) have expanded their Right to Try frameworks to include experimental regenerative therapies. Montana's expansion covers experimental autologous treatments that have passed Phase I safety trials. New Hampshire permits access to certain regenerative therapies under a state-level medical freedom framework. Both apply primarily to patients seeking access to experimental therapies, not to commercial allogeneic supplier relationships.

Mississippi & North Carolina Stem Cell Intervention Laws

Mississippi and North Carolina have each passed Stem Cell Intervention (SCI) laws allowing licensed physicians to use investigational stem cell therapies for patients with severe chronic or terminal illness, under physician oversight and with informed consent. Structured similarly to the original Texas HB 810 framework, these laws typically require the intervention to have some basis in human clinical trial data.

Arizona — SB 1214 (Arizona Stem Cell Therapy Act) Pending — Senate Floor as of March 2026

Arizona's SB 1214 cleared the Senate Health & Human Services Committee in February 2026 and is heading to the full Senate floor. It is not yet law but is the most significant pending stem cell legislation in the country as of this writing.

  • Modeled after Florida SB 1768: Authorizes licensed MDs and DOs to perform non-FDA-approved stem cell and birth tissue therapies for orthopedics, wound care, and pain management
  • Supplier requirements: Products must come from FDA-registered facilities accredited by AATB, AABB, or similar organizations — explicitly naming AATB
  • Informed consent: Required with full disclosure of non-approval status, risks, benefits, and alternatives
  • Fetal tissue prohibition: Cells from aborted fetuses or embryos explicitly banned — willful violations classified as a Class 5 felony
  • Civil remedies: Patients harmed by violations may seek $10,000 per violation plus attorney fees
  • Status: Passed committee February 19, 2026. Moving to full Senate floor vote.

This legislation is not yet law. Verify current status and consult legal counsel before making any clinical or sourcing decisions in reliance on its provisions.

Frequently Asked Questions

Does Florida SB 1768 cover exosome biologics?
Florida SB 1768 specifically covers stem cell therapy using adult-derived human cells and tissues. Exosomes are not explicitly named in the statute. Whether exosome biologics fall within its scope for any specific use is a legal question practitioners should discuss with qualified legal counsel. Stem Nova Network's topical cosmetic exosome biologics are positioned as cosmetic topical products only and are not marketed under SB 1768 or any other therapeutic framework.
What is the difference between AATB and AABB accreditation?
Both are voluntary accreditation bodies with rigorous standards. AATB (American Association of Tissue Banks) focuses specifically on tissue banks and tissue establishments — including those producing UCT-MSC biologics from birth tissue. AABB (Association for the Advancement of Blood & Biotherapies) focuses primarily on blood banking, transfusion medicine, and cellular therapies. Florida SB 1768 and Arizona SB 1214 both name AATB as an acceptable accrediting body.
Does state stem cell law override FDA enforcement?
No. State laws create pathways for physicians to practice medicine under state medical board authority — they do not override FDA's jurisdiction over the products themselves. The FDA retains authority to regulate HCT/P products under federal law regardless of what state law permits. This creates legal tension that practitioners in affected states should monitor carefully. Qualified legal counsel is strongly recommended.
What is cGTP and how does it differ from cGMP?
Current Good Tissue Practice (cGTP), governed by 21 CFR Part 1271, is the correct manufacturing standard for HCT/P products including UCT-MSC stem cells and exosome biologics. Current Good Manufacturing Practice (cGMP) applies to pharmaceutical drugs. Suppliers using "cGMP" language for tissue-derived biologic products may be mischaracterizing their regulatory category. Florida SB 1768 and Arizona SB 1214 both reference 21 CFR Part 1271 — making cGTP the applicable standard.
What documentation should I require from a stem cell biologic supplier?
At minimum: AATB accreditation confirmation, FDA establishment registration number, and a lot-specific Certificate of Analysis covering post-thaw viability, flow cytometry (CD90/CD166), sterility, endotoxin, mycoplasma, and a full nine-marker viral panel. For Florida practitioners operating under SB 1768, supplier AATB accreditation and 21 CFR Part 1271 compliance are legally required — not just best practice.
What is the status of Arizona SB 1214?
As of early March 2026, Arizona SB 1214 has cleared the Senate Health & Human Services Committee and is headed to the full Senate floor for a vote. It has not yet been signed into law. Practitioners in Arizona should monitor its progress and consult legal counsel before making any clinical or sourcing decisions in reliance on the bill's provisions.
Is stem cell therapy legal in California?
California's SB 512 is a disclosure law — it does not authorize non-FDA-approved stem cell therapy. California's Medical Board has actively warned licensees against administering unapproved regenerative medicine products. The only legal pathway for these products in California is within a formal FDA-approved IND clinical trial. Practitioners in California should not rely on SB 512 as authorization to administer unapproved products.
