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. The percentage of thymulin-containing cells increases gradually as a function of time, from 10% at day 4 to 90% at day 14. Furthermore, this increase can be prevented by the addition of thymulin in the culture medium. These data suggest a feedback control of thymulin secretion by thymic epithelial cells.
利用单克隆抗胸腺素抗体通过免疫荧光技术研究了培养的人胸腺上皮细胞中胸腺素(以前称为胸腺血清因子,FTS)的存在情况。含胸腺素细胞的百分比随时间逐渐增加,从第4天的10%增加到第14天的90%。此外,在培养基中添加胸腺素可阻止这种增加。这些数据提示胸腺上皮细胞对胸腺素分泌存在反馈控制。
