Abstract

Abstract: The objective of the present study was to evaluate the effect of porcine Mesenchymal Stem Cells (MSCs) secreted factors on bovine in vitro embryo development by using MSCs in different culture systems: SOF medium, SOF medium conditioned by MSCs in monolayer and in reverse drop and by embryo culture in co-culture with MSCs. Statistically highly significant differences were noted between the number of blastocysts derived cultures in all tested culture systems. The in vitro culture in SOF turned out to be the most optimal. Statistically highly significant differences were observed in the number of blastocyst obtained between SOF and SOF in co-culture with MSCs ( p < 0.0001), and between SOF and SOF conditioned (monolayer and drop) ( p < 0.00001). The trials to produce blastocysts in SOF conditioned by MSCs in reverse drops and monolayer failed. The blastocysts were obtained and analysed by TUNEL only in two out of four experimental groups: SOF and SOF in co-culture with MSCs. There were no significant differences between any of analysed blastocysts' groups neither in the total number of nuclei nor in the apoptotic features. Neither medium conditioning by MSCs in monolayer and in reverse drop nor embryo culture in co-culture with MSC turned out to be effective.
