    Summary
    Furthermore, this increase can be prevented by the addition of thymulin in the culture medium.

    Summary · context
    The percentage of thymulin-containing cells increases gradually as a function of time, from 10% at day 4 to 90% at day 14.
    Summary · context
    The presence of thymulin (formerly called Facteur Thymique Sérique, FTS) in cultured human thymic epithelial cells was studied using a monoclonal anti-thymulin antibody in an immunofluorescence technique.
