Embodiment 1
[0036] A method for preparing goat pluripotent stem cells induced by a complete small molecule compound, comprising the following steps:
[0037] 1. Isolation of goat ear margin fibroblasts and mouse fetal fibroblasts
[0038] Collect goat ear margin tissue pieces within 30 days from the goat farm, wash them three times with PBS buffer containing double antibodies, cut the tissue pieces with sterilized ophthalmic scissors, and place the small tissue pieces evenly on the culture dish In the process, turn it upside down and observe whether the tissue block is firmly attached to the wall in time, add an appropriate amount of high-glucose medium containing 10% FBS for culture, try to prevent the tissue block from floating, and then place it at 37°C, 5% CO 2 cultured in an incubator. The culture medium can be supplemented in an appropriate amount the next day, and then the medium is changed every two days. . Cells can be subcultured when they reach 90% confluence. Isolation met...
