Biologics Quality Standards at Rebuild Regen: 5 Certifications We Require From Every Supplier

Medical-grade biologics sourcing is the practice of procuring stem cells, exosomes, and other regenerative products exclusively from FDA-registered, cGMP, and AABB/AATB-certified tissue banks — the standard Rebuild Regen Medical Clinic applies to every treatment.

This standard is not legally required of every regenerative medicine provider. It is the standard Rebuild Regen chose to hold itself to because the biological products we introduce into patients require a documented quality chain that extends from the donor source through processing, testing, storage, and delivery.

When a clinic cannot or will not provide certification documentation for their biologics, the patient has no way to evaluate what was actually put in their body. At Rebuild Regen, every product we use has a verifiable certification chain and a lot-specific certificate of analysis (COA). Patients who want to review these documents are welcome to ask for them.

What Medical-Grade Biologics Sourcing Means

Medical-grade biologics sourcing goes beyond purchasing from a commercial supplier. It requires that the supplier meet the highest quality standards applicable to human cellular and tissue products, that those standards are maintained through active certification (not just one-time approval), and that each product lot is individually tested and documented before clinical use.

The alternative, and a common shortcut in the regenerative medicine market, is sourcing from uncertified or minimally regulated suppliers because the products are cheaper, more available, or require less paperwork. This shortcut transfers unknown risk to the patient. At Rebuild Regen, it is not acceptable.

The 5 Certifications We Require From Every Supplier

Certification 1: AABB Accreditation

AABB (formerly the American Association of Blood Banks) is an international, non-profit organization that sets standards for blood banking, transfusion medicine, and cellular therapy. AABB accreditation for tissue banks and cellular therapy providers requires an on-site assessment of donor screening, product testing, processing procedures, labeling, storage, and distribution systems.

AABB accreditation is not a one-time certification. It requires ongoing compliance with published standards and periodic re-inspection. A supplier whose AABB accreditation has lapsed is no longer AABB-accredited, regardless of prior status.

The DayZero™ tissue bank (ZEO ScientifiX) holds active AABB accreditation. This means donor screening, processing, and release testing protocols meet AABB cellular therapy standards.

Certification 2: FDA-Registered cGMP Facility

Current Good Manufacturing Practice (cGMP) is the FDA's framework for the manufacturing of biological products, drugs, and medical devices. cGMP regulations establish standards for quality systems, process controls, facility design, personnel training, record-keeping, and product testing.

An FDA-registered cGMP facility has registered with the FDA and operates manufacturing processes that conform to 21 CFR standards. FDA registration is not FDA approval of the product itself. It is documentation that the facility operates under a defined quality system subject to FDA inspection.

cGMP compliance ensures that what the label says is in the vial is actually in the vial, at the concentration stated, with the purity and sterility documented.

Certification 3: ISO-7 Clean Room Processing

ISO-7 clean room classification (also known as Class 10,000) defines an environmental standard for airborne particulate contamination. ISO-7 environments maintain fewer than 352,000 particles per cubic meter at 0.5 microns or larger, with positive air pressure, HEPA filtration, and controlled access.

Stem cell and exosome processing in an ISO-7 clean room ensures that the cellular products are processed in an environment that minimizes contamination risk. Lower clean room classifications introduce unacceptable contamination risk for products that will be injected into patients.

Certification 4: AATB Standards Compliance

The American Association of Tissue Banks (AATB) sets standards specifically for human tissue banking, including musculoskeletal, cardiovascular, and reproductive tissue as well as cell therapy products. AATB standards address donor eligibility, infectious disease testing, processing, preservation, storage, and distribution.

For umbilical cord-derived products (stem cells, Wharton's Jelly, perinatal EVs), AATB standards provide the framework for responsible sourcing that does not compromise donor or patient safety.

Certification 5: 21 CFR Part 1271 Registration

Title 21, Code of Federal Regulations, Part 1271 establishes FDA requirements for human cells, tissues, and cellular and tissue-based products (HCT/Ps). Registration under 21 CFR Part 1271 requires that the supplier identify all HCT/Ps manufactured, maintain donor eligibility determinations, follow current good tissue practice (CGTP), and report any adverse reactions related to their products.

All DayZero™ products from ZEO ScientifiX are 21 CFR Part 1271 registered. This is the regulatory foundation for the legal use of these products in clinical settings.

Certificate of Analysis on Every Lot

Beyond facility certifications, Rebuild Regen requires a certificate of analysis (COA) for every lot of biological product used in patient treatments. The COA documents the specific test results for that lot: cell viability (for stem cells), particle count (for exosomes), sterility testing, mycoplasma testing, and potency markers.

A COA for a product means that the specific vial used in your treatment was tested as part of its manufacturing lot and met the release specifications before being approved for clinical use. It is not a generic claim about what the product contains. It is a specific test result for the specific lot.

Patients who receive biologics without a documented COA have no way to verify that the product they received met any particular standard. Rebuild Regen maintains COA records on file for every biological product administered.

How This Standard Applies at Rebuild Regen

Every product used in a biological treatment at Rebuild Regen Medical Clinic at 3320 N Federal Hwy #101, Lighthouse Point, FL meets all 5 certifications. The current supplier, ZEO ScientifiX, provides the DayZero™ product line: umbilical cord stem cells, perinatal-derived exosomes, Wharton's Jelly Matrix, and Patient Pure X (PPX).

The decision to use DayZero™ was made based on the documentation standard, not on product availability or price. There are cheaper biologics on the market. There are products marketed with impressive claims and minimal documentation. Rebuild Regen chose DayZero™ because the complete certification chain is verifiable and the COA accompanies every lot.

This is what medical-grade biologics sourcing looks like in practice. It is not a marketing claim. It is an operational standard with a documentation trail.

Is the Quality Standard of Your Provider's Biologics Verifiable?

The regenerative medicine market includes providers who source biologics responsibly and providers who do not. The certifications described above are the minimum verifiable quality standard for responsible clinical use of regenerative biologics.

Questions to ask any provider before consenting to biologics treatment:

What is the name of your biologics supplier?
Is the supplier AABB-accredited?
Is the facility FDA-registered cGMP?
Is there a COA for the specific lot being used in my treatment?
Is the product 21 CFR Part 1271 registered?

If a provider cannot answer these questions, the due diligence on their biologics has not been done. At Rebuild Regen, these questions have already been answered before any product is purchased for clinical use.

When Biologics Do Not Meet This Standard

Uncertified or minimally documented biologics carry risks that certified products have addressed through systematic quality controls. These risks include contamination from inadequate clean room processing, donor-transmitted infections from inadequate donor screening, product mischaracterization (the concentration or contents differ from the label), and reduced efficacy from inadequate viability or processing standards.

The clinical consequences of low-quality biologics range from no effect (the product did nothing because it was degraded or mischaracterized) to adverse events (contamination or donor screening failures). Neither outcome is acceptable. Rebuild Regen's quality standard exists to ensure that neither is a risk for patients treated here.
