Testicular compartment that includes rete testis and the adjacent transitional zone (TZ) of seminiferous tubules has been examined only by light and electron microscopy until now. However, recent data suggest that adult Sertoli cells (SCs) located in this compartment are capable to commence active proliferation both in vitro and in vivo, and hence, are not completely differentiated. The present study is first to investigate mouse rete testis and TZ during the postembryonic development and is intended to determine new protein markers for cells of this compartment, the state of their differentiation, and also their proliferative activity. It was demonstrated that rete testis cells were stained for SC marker Wt1 transiently, until day 25 of postembryonic development, then the staining disappeared. Another SC marker Dmrt1 that involved in the process of SC differentiation was not expressed in the rete testis cells during the postnatal development and in the adult state. One more feature that distinguished rete testis cells from SCs was lower proliferative activity of rete testis cells in 2–6 days old mice. SCs from TZ expressed Wt1 at all ages examined. However, at earlier ages, they were heterogeneous on Dmrt1 expression, and only by day 25, Dmrt1 expression was completely disappeared from TZ SCs. It is interesting that on day 18 when SCs in seminiferous tubules complete differentiation and exit from cell cycle proliferation of TZ SCs was at significantly higher level. It is also showed that in 3D culture, Wt1+ cells isolated from rete testis and TZ of 60 days old GFP male mice were capable to form seminiferous tubules de novo in cooperation with testicular cells from 6 days old mice.
