After incubation with thymosin, a thymic hormone, normal bone marrow rosette-forming cells acquire T-cell characteristics, including increased sensitivity to azathioprine, anti-lymphocyte serum, and anti-theta serum. This activity of thymosin provides a new sensitive and reproducible bioassay for thymosin, and is well correlated with an in vivo graft-versus-host assay. In addition, incubation of spleen cells from adult thymectomized mice with thymosin in vitro restores to normal their diminished sensitivity to azathioprine and anti-lymphocte serum.
在用胸腺素(一种胸腺激素)孵育后,正常骨髓玫瑰花结形成细胞获得T细胞特性,包括对硫唑嘌呤、抗淋巴细胞血清和抗θ血清的敏感性增加。胸腺素的这种活性为胸腺素提供了一种新的灵敏且可重复的生物测定方法,并且与体内移植物抗宿主测定法密切相关。此外,将成年去胸腺小鼠的脾细胞在体外用胸腺素孵育,可使其对硫唑嘌呤和抗淋巴细胞血清降低的敏感性恢复正常。
