New research on the teeth of fossilized dinosaur embryos indicates that the eggs of non-avian dinosaurs took a long time to hatch—between about three and six months. The study, led by scientists at Fl...
Knockout of Myostatin by Zinc-finger Nuclease in Sheep Fibroblasts and Embryos
Myostatin Zinc-finger Nucleases Knockout, Sheep
2016/11/10
Myostatin (MSTN) can negatively regulate the growth and development of skeletal muscle, and natural mutations can cause “double-muscling” trait in animals. In order to block the inhibiting effect of M...
Analysis of ENPP2 in the Uterine Endometrium of Pigs Carrying Somatic Cell Nuclear Transfer Cloned Embryos
Pig Pregnancy ENPP2 LPA SCNT
