Abstract
A method of direct transdifferentiation of somatic cells into other somatic cells may be convenient and still have good reproducibility, excellent production efficiency, and short performed time. Methods for direct transdifferentiation of somatic cells into other somatic cells may include: (a) introducing a GLIS family gene, a mutated GLIS family gene or a gene product thereof into somatic cells; and (b) culturing the gene-introduced somatic cells in a culture medium containing a component that induces differentiation of the somatic cells or precursor cells of the somatic cells into other somatic cells.
Claims2
A method for direct transdifferentiation of somatic cells into cardiomyocytes, the method comprising:
- (a) introducing (i) a GLIS1 gene, a mutated GLIS1 gene comprising the nucleotide sequence of SEQ ID NO:
- 2, or a gene product thereof, and (ii) a transcription factor of cardiomyocytes, into somatic cells;
- and
- (b) culturing the somatic cells of (a) in a culture medium containing a growth factor of cardiomyocytes,
- wherein the somatic cells are selected from fibroblasts, mesenchymal stem cells and adipose tissue-derived stromal stem cells,
- wherein the transcription factor of cardiomyocytes is at least one of Tbx5, GATA4, and Mef2c, and
- wherein the growth factor of cardiomyocytes is at least one of FGF and VEGF.
