Relationship of a mouse Sertoli cell line (MSC-1) to normal Sertoli cells
Recently, a mouse Sertoli cell line (MSC-1) was established from transgenic mice carrying a fusion gene composed of human Mullerian inhibitory substance transcriptional regulatory sequences linked to the SV40 T-antigen gene. This cell line contained a morphologically heterogeneous population of cells that expressed characteristic Sertoli cell mRNAs such as transferrin, the ß-subunit for inhibin, and sulfated glycoprotein-2 (SGP-2). In this study, we compared various characteristics of MSC-1 cells to primary cultures of Sertoli cells from immature rats or adult mice. Our observations indicated that: 1) These cells were ultrastructurally similar to mouse Sertoli cells in culture; 2) MSC-1 cells expressed mRNA for androgen-binding protein (ABP) and SGP-1, but not the receptor for FSH; 3) The expression of SGP-2 mRNA and secretion of SGP-2 increased approximately 2-fold when cells were cultured at 41Â°C, the nonpermissive temperature for the SV40 virus, while SGP-1 and transferrin mRNA levels and secretion were unaffected; 4) Proliferation of these cells was serum-dose dependent and temperature dependent and could be inhibited by incubating MSC-1 cells at 41Â°C; 5) Proliferation was also significantly reduced after cells were incubated in the presence of dibutyryl cAMP (dbcAMP) for 6 days; 6) Fifteen subcultures produced from single MSC-1 cells displayed similar levels of mRNA expression for transferrin or SGP-1. Together these data indicate that the MSC-1 cell line is composed of a single cell type displaying numerous characteristics of Sertoli cells. This cell line may provide a unique source of tissue for studying various aspects of Sertoli cell behavior.
