Embodiment 1
[0043] Embodiment 1, pig somatic cell nuclear transfer
[0044] 1. In vitro maturation culture of porcine oocytes
[0045] Take the pig ovary from the slaughterhouse, wash it three times with normal saline containing 100U / mL penicillin and 100U / mL streptomycin, and then use a 10mL disposable syringe and a 18-gauge needle to extract follicles with a diameter of 3-6mm Cumulus-oocyte complexes (COCs) wrapped with 3-5 layers of cumulus cells were selected from the liquid. COCs were rinsed twice with normal saline containing 100U / mL penicillin and 100U / mL streptomycin, then transferred to IVM solution, at 39°C, saturated humidity, 5% CO 2 Cultured in the incubator for 42h.
[0046] 2. Isolation and culture of porcine fetal fibroblasts
[0047] Pig fetal fibroblasts were prepared according to the following steps in turn:
[0048] 1. Take out the fetus from the uterus of pregnant sows at gestation day 35, wash with DPBS buffer solution containing 100U / mL penicillin and 100U / mL st...
