Abstract

To establish a storage system for isolated bovine luteal endothelial cells (LECs), we investigated the basal and tumor necrosis factor (TNF) α-stimulated production of endothelin-1 (ET-1) and prostaglandin (PG) F2α in unfrozen and frozen-thawed LECs until passage 10. LECs were obtained from developing corpora lutea (CL; days 5-7 of the estrous cycle) using enzymatic digestion and magnetic beads coated with lectin BS-1. The LECs were frozen at -80 C or further cultured and/ or passaged until passage 10 in DMEM/Ham's F-12 supplemented with 10% calf serum. The hormonal productions of unfrozen and frozen/thawed LECs were compared through passages 2-10. When both the unfrozen and frozen/thawed cells reached confluence, the culture medium was replaced with fresh medium containing 0.1% bovine serum albumin (BSA), and the cells were incubated with TNFα (50 ng/ml) for 12 h. The basal productions of ET-1 and PGF2α by the unfrozen and frozen/thawed LECs were similar at passage 2. The basal production of PGF2α by LECs was not altered by passage and storage at -80 C, whereas the basal production of ET-1 decreased from passage 2 and 3 to passage 4 in the unfrozen LECs and from passage 2 to passage 3 in the frozen/thawed LECs. However, production of ET-1 by the unfrozen and frozen/thawed LECs was similar between passages 4-10 and passages 3-10, respectively. Exposure of LECs to TNFα increased (P<0.05) ET-1 and PGF2α production by the unfrozen and frozen-thawed LECs in all passages examined. Thus, LECs obtained from developing CLs and stored until passage 10 can be used for study of the physiology of LECs in vitro.
