Results from this study2

No result from this study comes from a test of the peptide.

Natural levels measured1

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

  1. 01AnimalEndogenous levelAnimal study (in vivo)Other

    In mice, peptidomic analysis found the body's own thymosin beta‑4 enriched among subcommissural organ-derived peptides.

    In plain wordsIn mice, the body's own thymosin beta‑4 was enriched in a brain gland called the subcommissural organ.

    Summary
    Unbiased peptidomic analysis revealed enrichment of three SCO-derived peptides, namely, thymosin beta 4, thymosin beta 10 and NP24
    1 context sentence
    Summary · context
    Mouse strains expressing Cre recombinase from endogenous promoter/enhancer elements of these genes were used to genetically ablate SCO cells during embryonic development, resulting in severe hydrocephalus and defects in neuronal migration and development of neuronal axons and dendrites.

    This result measures the body's own Thymosin beta-4 (human). Nobody was given the peptide. It is not evidence about taking it.

Studies that did not test the peptide alone1

In this study, Thymosin beta-4 (human) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Thymosin beta-4 (human).

  1. 02AnimalNot a test of Thymosin beta-4 (human) aloneAnimal study (in vivo)Efficacy outcome

    In SCO-ablated mouse brain ventricles, reintroduction of a mix of thymosin beta‑4, thymosin beta 10 and NP24 substantially rescued developmental defects.

    In plain wordsIn mice, putting back a mix of three peptides, including thymosin beta‑4, largely rescued brain development defects.
