Results from this study3

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

Natural levels measured3

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.

    In the Xenopus thymus, immunohistochemical analysis found the thymic hormone thymosin alpha1.

    In plain wordsIn Xenopus frogs, the body's own thymosin alpha1 was found in the thymus.

    Summary
    Immunohistochemical analysis revealed that the neuropeptides substance P, neuropeptide Y, somatostatin, calcitonin gene related peptide, and vasoactive intestinal polypeptide and the thymic hormones thymosin alpha1, thymosin beta4, and thymopoietin are found in the Xenopus thymus.

    This result measures the body's own Thymosin alpha-1. Nobody was given the peptide. It is not evidence about taking it.

    In the Xenopus thymus, RT-PCR corroborated the presence of thymic hormones including thymosin alpha1.

    In plain wordsIn Xenopus frogs, a second test, RT-PCR, also showed the body's own thymosin alpha1 in the thymus.

    In the Xenopus thymus, double staining showed that neuropeptides and thymic hormones, including thymosin alpha1, are coexpressed within the epithelial cell component.

    In plain wordsIn Xenopus frogs, the body's own thymosin alpha1 appeared in the same thymus cells as neuropeptides.
