WebThere are enough cells in a blastocyst that a few trophectoderm cells can be removed without disturbing the developing blastocyst. These cells can be tested for chromosome aneuploidy using preimplantation genetic screening (PGS), or specific conditions such as cystic fibrosis, often known as preimplantation genetic diagnosis (PGD). WebApr 5, 2024 · We first examined Ctcf expression levels in mouse embryonic fibroblasts (MEFs), reprogramming intermediates (pre-iPSCs), iPSCs, and mouse ESCs (mESCs) by qRT-PCR and western blot. We found that Ctcf was upregulated in mESCs and iPSCs compared with MEFs and pre-iPSCs (Figures 1 A and 1B).We also noticed a gradual …
