Novel method for obtaining goat-induced multi-potent stem cells

The invention discloses a novel method for obtaining goat-induced multi-potent stem cells. The novel method comprises the following steps: firstly, extracting total RNAs from a testicular tissue, a skin tissue and a small intestine tissue of a goat; performing reverse transcription to obtain a cDNA segment; and with the cDNA segment as a template, cloning to obtain coding sequences of Oct4, Sox2, K1f4 and c-Myc multifunctional transcription factors of the goat. Fetal fibroblast cells of the goat and a mouse are obtained by utilizing a trypsin digestion method, feed-layer cells and a cell culture solution are prepared. mRNA of each multifunctional transcription factor obtained by utilizing an in-vitro transcription test is mediated by lipidosome 2000 to transfect the goat fetal fibroblast cells, so that goat iPS cells are prepared. A cell colony which is flatly cloned, dense, large in nuclear-cytoplasmic ratio, clear in cloning boundary and strong in light refraction is judged as a goat iPS cell colony. The goat iPS cell colony is picked in a monoclonal mode, digested by pancreatic enzyme and independently inoculated to a novel culture pore plate inoculated with a feeding layer to be further cultured to obtain a goat iPS cell line.
