FAQs

Where do your MSCs come from?

Our mesenchymal stem cells are harvested from donated umbilical cords via scheduled cesarean sections. The women donating their umbilical cords undergo rigorous health screenings to ensure we are using the most active and viable umbilical cord stem cells. 


Are your products FDA approved?

Short answer: No, most umbilical cord–derived biologics are not FDA-approved drugs. And that’s not necessarily a red flag—it’s a matter of how they’re regulated.

These products typically fall under regulation by the U.S. Food and Drug Administration as 361 HCT/Ps (Human Cells, Tissues, and Cellular and Tissue-Based Products). That means they are regulated as tissue products—not drugs. They are not required to go through the FDA drug approval process. They are expected to meet specific criteria, including: Minimal manipulation, homologous use, donor screening and testing, sterility and safety standards.

These products can be legally marketed and used when they meet 361 criteria. They are not “unregulated”—they are regulated differently. Safety testing (sterility, endotoxin, infectious disease screening) is still required. Where the confusion—and concern—comes in: Some companies market these products like FDA-approved treatments or make drug-level claims.

A responsible, compliant approach looks like: Being clear that the product is not FDA-approved as a drug, positioning it as a biologic support tool—not a cure, and using data-backed language (cell markers, viability, growth factors) Avoiding claims such as guaranteed outcomes and tissue regeneration, or disease treatment.

There is real biologic potential in this space with strong scientific evidence supporting the biological mechanisms of these products (anti-inflammatory effects, cell signaling, growth factors). Early clinical data is promising. There is also real variability—and real marketing noise. The difference comes down to transparency and positioning. 


How do you ensure safety?

We ask our donors 210 medical history questions in addition to sending 10% of each batch out for 3rd party testing. If one fails, we discard the entire batch. 


Is there risk of rejection?

UC-MSCs do not express major histocompatibility complex (MHC) antigens of the class II subtype and contain low levels of MHC molecules of the class I subtype. UC-MSCs also lack the co-stimulatory molecules essential for immune detection, including CD40, CD80, and CD86. 

What you’ll typically see on a certificate of analysis (COA):

  • Positive markers: CD73, CD90, CD105

  • Negative markers: CD34, CD45, CD14, CD19, HLA-DR (which corresponds to MHC II)

Baseline state (fresh or minimally cultured UC-MSCs):

  • MHC class I: low to moderate expression

  • MHC class II: negative or very low

  • This is part of why they’re considered “immune-privileged” or “immune-evasive”, making them attractive for allogeneic (donor-derived) use.

Thus, MSCs generally have low immunogenicity and can avoid immune rejection by the recipient, which serves as the foundation for their successful application without needing to match the donor to the recipient.
