Abstract:
본 발명은 돼지배아줄기세포주, 및 단위생식(parthenogenesis)법을 이용하여 돼지 미성숙 난자로부터 배반포(blastocyst)를 생산하고, 생산된 배반포를 부화시켜 돼지배아줄기세포를 제조하는 방법에 관한 것으로서, 본 발명의 방법으로 돼지배아줄기세포를 보다 효율적으로 제조할 수 있다.
Abstract:
PURPOSE: A manufacturing method of pig embryonic stem cells from the pig embryonic stem cells and pig immature ovum is provided to have pluripotency which is similar to pig embryonic stem cells originated from blastodermic vesicle. CONSTITUTION: A manufacturing method of pig embryonic stem cells from the pig embryonic stem cells and pig immature ovum comprises the following steps: maturing ovum by cultivating immature ovum of the pig; parthenogenesizing the matured ovum by activating by electrostimulation; cultivating and incubating the activated ovum with blastocyst; and cultivating inner cell mass originated from the incubated blastodermic vesicle and producing the ovum originated embryonic stem cell. The ovum in the second step is the first or the second ovum. The blastocyst cultivation in the third step is completed in a culture medium in which the fetal bovine serum (FBS) is included. The inner cell mass cultivation in the fourth step is completed in the culture medium including LIF, and BFGF or SCF.
