The corpus luteum (CL) is composed to various cells, such as luteal steroidogenic cells (LSCs), luteal thecal steroidogenic cells (LTCs), luteal endothelial cells (LECs), fibroblast, immune cells and blood cells. The life span of CL is controlled by proliferation and apoptosis of luteal cells. Therefore, this study investigated apoptotic factors in luteal cells derived from bovine CL. The CL tissues were collected from bovine ovaries and luteal cells were isolated from middle phase CL. Then, LTCs and LECs were separated according to cellular morphology from LSCs. The expression of Bax, Bcl-2, Fas and tumor necrosis factor 1 receptor (TNF1R) mRNA and protein were analyzed using quantitative RT-PCR and western blot. Results show that, Bax and TNFR1 mRNA expression were significantly increased at late group than early and middle groups, otherwise Bcl-2 were significantly decreased at late group than early group (P<0.05). Fas mRNA expression were significantly decreased in middle group compared to early and late groups (P<0.05). In addition, Bax and Bcl-2 mRNA in LTCs was lower than LSCs, Fas mRNA was higher than LSCs. The Bcl-2 protein expression was lower at LTCs than LSCs, especially Fas protein in LTCs was significantly lower than LSCs and LECs (P<0.05). Otherwise, TNFR1 protein of LTCs were similar with LSCs but higher compared with LECs. In conclusion, we suggest that the results may help understanding of apoptosis ability in luteal cells according to cell type during CL regression of estrous cycle.
