Abstract:

Platelet-derived growth factor (PDGF) is one family of growth factors that regulate cell growth and differentiation. Rat Leydig cells express PDGF-β receptor (PDGFRB) during pubertal development. However, the mechanism of PDGF in the regulation of Leydig cell development is unclear. In the present study, rat immature Leydig cells were isolated from the testes of 35-day-old Sprague-Dawley rats and treated with 1 and 10 ng/mL of PDGF-BB. After 24 h of treatment, these cells were harvested for genomics profiling and the medium steroids were measured. 1 and 10 ng/mL PDGF-BB significantly increased androgen production by rat immature Leydig cells. Genomics profiling analysis showed that the expression levels of steroidogenic acute regulatory protein (Star) were increased by 2-fold. Further analysis showed that Fos expression level was increased 2- and 5-fold by 1 and 10 ng/mL PDGF-BB, respectively. In conclusion, PDGF-BB stimulated the differentiation of rat immature Leydig cells via regulating Star.
