Trophectoderm (TE) biopsying for single nucleotide polymorphisms (SNPs) analysis is being implemented as a tool for the selection of elite bovine embryos. This biopsy method renders ample cells for analysis without compromising the inner cell mass (I

Autor: Henrik Callesen, Kristine K. Freude, Poul Hyttel, Jan O. Secher

Publikováno v: Secher, J, Callesen, H, Freude, K K & Hyttel, P 2016, ' Initial embryology and pluripotent stem cells in the pig-the quest for establishing the pig as a model for cell therapy ', Theriogenology, vol. 85, no. 1, pp. 162-171 . https://doi.org/10.1016/j.theriogenology.2015.09.017

The quest for porcine pluripotent stem cells (PSCs) was initiated in the early 90s. Initially, it was the intention to benefit from these cells for production of genetically modified pigs using homologous recombination followed by derivation of chime

Porcine somatic cell nuclear transfer (SCNT) has been used extensively to create genetically modified pigs, but the efficiency of the methodology is still low. It has been hypothesized that pluripotent or multipotent stem cells might result in increa

Optimal bovine in vitro oocyte maturation (IVM) is a prerequisite for subsequent optimal blastocyst rates. Ovum pick-up (OPU), by which cumulus–oocyte complexes (COC) are collected in vivo, is performed outside a laboratory and often requires IVM t

Differential staining is an immunocytochemical staining that visualizes trophectoderm (TE) and the inner cell mass (ICM) of the blastocysts. It is used to determine the blastocyst quality, but could also be a useful tool to assess the integration sit
