Establishment and characterization of an immortalized bovine luteal cell line. (PubMed, Front Vet Sci)
The bovine corpus luteum (CL) is critical for pregnancy establishment and maintenance via progesterone (P4) secretion...Furthermore, Co-culture with SV40T-IBLC significantly enhanced the viability of bovine endometrial epithelial cells (BEEC) by 34.2% after 72 h of co-incubation (p < 0.01), increased intracellular lipid droplet abundance of BEEC, and upregulated the mRNA expression of endometrial receptivity-related genes including EGF and LIF, with no significant alteration in BEEC apoptosis rate. In conclusion, this immortalized cell line retains core functional characteristics of PBLC, providing a stable, homogeneous in vitro model for bovine reproductive research.
