Development of cloned embryos from porcine neural stem cells and amniotic fluid-derived stem cells1
The aim of this study was to determine the developmental ability of cloned embryos derived from porcine neural stem (NS) cells, amniotic fluid-derived stem (AFS) cells, differentiated cells from NS and AFS cells, fetal fibroblast (FF) cells, adult fibroblast (AF) cells and mammary gland epithelial (...

AFS cells widely expressed NogoA, DCX, CyclinD2, CD133, Hes1, Nanog, Sox2, Oct4, Desmin and CD-90. Both NS and AFS cells were differentiated into astrocyte (GFAP+), oligodendrocyte (GalC+), neuron (NF+, NSE+ and MAP2+), adipocyte (LPL+ and PPARγ-D+), osteoblast (Osteonectin+ and Osteocalcin+), myocyte (myf-6+and myoD+) and endothelium (CD31+, CD34+, CD144+ and eNOS+).

The developmental potential of the cloned embryos derived from stem cells (NS and AFS cells) were higher (P < 0.05) than that of the cloned embryos derived from somatic cells (the differentiated cells from NS and AFS cells, FF cells, AF cells and MGE cells), which suggests that the undifferentiated state of the donor cells increases cloning efficiency.http://www.sciencedirect.com/science/article/pii/S1751731110000121neural stem cellsamniotic fluid-derived stem cellscloned embryosdevelopmental abilitypig |
