From: Maternal age affects equine day 8 embryo gene expression both in trophoblast and inner cell mass
Bisection of equine embryos at 8 days post-ovulation into an ICMandTE and a TE_part. a Step 1: Identification of the ICM and the TE; b Step 2: Definition of the cutting plane to isolate the ICM in one of the parts; c Step 3: Cutting of the embryo and separation of the two parts. ICMandTE: inner cell mass + trophoblast; TE part: pure trophoblast. NB: Here the trophoblast represents trophectoderm + endoderm and ICM is composed of epiblast cells
