An insoluble component of the thymus, previously shown to be capable of enhancing stem cell immigration into that organ, has been localized by immunofluorescence in perivascular basement membranes of the thymic medulla. It was found to be antigenically distinct from soluble thymic factor and from thymocyte membranes, and is thought to be responsible, in T-cell maturation, for the differentiation step preceding that imparted by thymic hormone.
胸腺的一种不溶性成分,先前已证明其能够增强干细胞向该器官的迁移,通过免疫荧光法已将其定位在胸腺髓质的血管周围基底膜中。发现它在抗原性上与可溶性胸腺因子和胸腺细胞膜不同,并且被认为在T细胞成熟过程中,负责胸腺激素作用之前的分化步骤。
