Abstract

The invention discloses a method for inducing cardiac differentiation of stem cells by utilizing small molecule compounds, relating to the fields of stem cell biology and regenerative medicines. The small molecule compounds refer to a type of carbamate compounds (I) or medicinal salts, hydrates, solvates and isomers thereof. The method comprises the following steps: adding the small molecule compounds into a differential medium to directly act on tested cells, continuously using the small molecule compounds according to the form and growth states of the tested cells and the identification conditions until the expression level of corresponding target genes in the tested cells is increased, and differentiating the tested cells into cardiomyocyte-like cells, wherein the stem cells comprise embryonic stem cells, induced pluripotent stem cells and mesenchymal stem cells. The experiment proves that after the inducers are added into the cell differentiation medium, the myocardial cell differentiation proportion of the stem cells is obviously improved. The differential medium containing a type of carbamate compounds or medicinal salts, hydrates, solvates and isomers thereof can be used for inducing the stem cells to be differentiated into myocardial cells.

Description

technical field [0001] The present invention relates to the field of stem cell biology and regenerative medicine, in particular to the use of small molecular compounds (a class of carbamate compounds or their pharmaceutically acceptable salts, hydrates, solvates and isomers) to induce stem cells to differentiate into myocardial Methods. Background technique [0002] Stem cell-based regenerative medicine has opened up a new and broad field for the development of life science and medicine. Researchers believe that stem cell (regenerative medicine) research has the potential to change the way humans respond to disease by repairing specific tissues or organs. Stem cell regenerative medicine has broad application prospects in the treatment of cardiomyopathy and other diseases that currently have no good treatment options. [0003] Stem cells are primitive undifferentiated cells that have the ability to differentiate into other cell types. According to different sources, stem c...
