Establishment of Embryo Culture System using Co-incubated Collagen Matrix Gel with Porcine Endometrial Cells
In order to achieve successful in vitro production of embryo, it is necessary to establish intrauterine environment during in vitro culture. Thus, this study was investigated to establish embryo culture system using co-incubated collagen matrix gel (CM) with endometrial epithelial cells (EC). Endometrial epithelial cells were isolated from porcine endometrium at follicular phase, the cells seeded in insert dish for co-incubation with CM-coated culture dish. Then, culture media treated with/without 2.0 IU/ml hCG or 10 ng/ml IL-1β. After incubation for 24 h, the co-incubated insert dishes were removed from CM-coated culture dish before embryo culture. Embryos at 48 h after in vitro fertilization (IVF) were cultured on the dish for 120 h with porcine zygote medium. We determined PTGS-2 expression in the ECs, VEGF protein in co-incubated CM with EC and observed cleavage rate and blastocyst development of embryos at 168 h after IVF. In result, expression of PTGS-2 was higher at co-incubated EC with hCG and IL-1β groups than EC without hCG and IL-1β. The VEGF protein was detected at co-incubated CM with EC, EC treated with hCG and IL-1β groups higher than CM group. Also, cleavage rate was no significantly difference among all group, however, blastocyst development was significantly higher in co-incubated CM with EC treated with hCG group than un-treated groups (p<0.05). Therefore, we suggest that novel embryo culture system using co-incubated collagen matrix gel with endometrial epithelial cells treated with IL-1β is beneficial and useful for enhancing the production of porcine blastocysts in vitro.
