Results from this study2

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.

    In cultured mouse thymic epithelial cells, the number of cells containing thymosin alpha‑1 increased progressively from Day 6 to Day 12 of culture.

    In plain wordsIn cells, the number of thymic cells that contained their own thymosin alpha‑1 rose from day 6 to day 12.

    Summary · context
    The secretory evolution of the thymic hormones (thymulin, thymosin alpha 1 and thymopoietin) in cultured thymic reticuloepithelial cells (TREC) was studied by immunocytochemical techniques using monoclonal anti-thymulin or anti-thymosin alpha 1 and polyclonal anti-thymopoietin antibodies (Ab).

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

  2. 02LabEndogenous levelIn vitro (cells)Other

    In cultured mouse thymic epithelial cells, thymosin alpha‑1 staining lay in cytoplasmic granules early and at Day 90, and throughout the cytoplasm at Day 12.

    In plain wordsIn cells, the cells' own thymosin alpha‑1 sat in granules early and late in culture, and was spread through the cell at day 12.

    Summary
    By light microscopy the staining of the three hormones was localized in some cytoplasmic granules at the beginning of the culture and at Day 90, while at Day 12 it was throughout the cytoplasm.
