In vitro pluripotency of epiblasts derived from bovine blastocysts.
Molecular Reproduction and Development 1995 September
Two experiments were conducted to compare the utility of in vitro- and in vivo-derived bovine blastocysts for the isolation of pluripotent epiblasts. In experiment 1, the inner cell masses (ICMs) of in vivo-collected blastocysts yielded a higher proportion of epiblasts after culture on STO feeder cells than ICMs from in vitro-produced blastocysts (P = .0157). In experiment 2, ICMs of in vivo-collected blastocysts that hatched on day 8 yielded a greater proportion of epiblasts after culture on STO feeder cells than ICMs from in vitro-produced blastocysts that hatched on day 8. The difference was reversed but smaller for blastocysts that hatched on day 9 (Interaction, P = .0125). Epiblasts from blastocysts that hatched on day 8 regardless of their source generated more differentiated cell lines in extended culture than did blastocysts that hatched on day 9. Extended epiblast culture yielded cells identifiable as products of the three embryonic germ layers that included epithelial cells, fibroblasts, neuronal cells, hepatocyte-like cells, and macrophage-like cells. Alkaline phosphatase activity combined with cell morphology identified the bovine epiblast cells and distinguished them from trophectoderm and endoderm that frequently contaminated epiblast cell cultures. In vivo-derived blastocysts, especially from early-hatching blastocysts, were a superior source of pluripotent epiblasts. Epiblast cells in this study all differentiated or senesced indicating that standard conditions for mouse embryonic stem cell culture do not maintain bovine epiblast cells in an undifferentiated state.
