Results from this study5

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

Natural levels measured2

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.

    Summary
    Immunostaining localized thymosin beta 4 in vivo in both growing and mature vessels as well as in other tissues.

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

    Summary
    The mRNA for one clone, thymosin beta 4, was increased 5-fold.
    1 context sentence
    Summary · context
    We performed differential cDNA hybridization using RNA from endothelial cells cultured for 4 hours on either plastic or basement membrane matrix (Matrigel), and identified early genes induced during the morphological differentiation into capillary-like tubes.

    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 alone3

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).
