References behind the TB-500 digest.

How to read these TB-500 references

These are the references for every quantitative claim in this TB-500 digest, numbered to match the inline markers across the site. They divide into two groups. References one through fifteen are the peer-reviewed scientific literature on thymosin beta-4 and its Ac-LKKTETQ fragment — structure, mechanism, wound, cardiac, neurological, and recent work. References sixteen through eighteen are the authoritative FDA sources behind the regulatory and access statements on the TB-500 legal status and FDA 503A category page; each was verified against a live FDA.gov page.

One note carries across the whole list, as it does across the whole site: where a study used full-length thymosin beta-4 rather than the TB-500 heptapeptide, the digest says so in the running text. The citation list does not relitigate that each time — the distinction lives in how each finding is described. Where a primary identifier is available it is a PubMed link; where the canonical record is a journal landing page, a DOI is given instead.

If you find a figure on this site that does not match its cited source, the contact page is the channel for a correction. Accuracy against the published record is the only thing this digest is for.
