Different developmental stages of goat embryos produced <i>in vitro</i>.

<p>Transferred IVF blastocysts (a) or SCNT blastocysts (b) showed clear inner cell masses (ICMs) and trphoectodermal cells (TE) under bright field at Day 7. Both the IVF blastocysts (c) and SCNT blastocysts (d) attached to the endometrial epithelial cells after co-cultured for 24 h. The trophoblast of IVF (e) and SCNT (f) underwent outgrowth on the epithelial cells monolayer after co-cultured for 72 h. Scale bar = 50 µm.
