23 Jul Small-molecular compound combination and method for inducing differentiated cells to prepare chondrocytes by using small-molecular compound combination
Abstract
The invention discloses a small-molecular compound combination and a method for inducing differentiated cells to prepare chondrocytes by using the small-molecular compound combination. The method is used for preparing the chondrocytes by directional induction of the differentiated cells. The directed induction includes inhibition of the activity of lysine deacetylase, inhibition of a signal pathway of TGF-beta, inhibition of the activity of PKC, inhibition of the activity of DNA methyltransferase, inhibition of the activity of histone methyltransferase, activation of a WNT/beta-catenin signalpathway, activation of a cAMP signal pathway and activation of an RA signal pathway; the small-molecular compound combination includes compounds for regulating and controlling the signal pathways and/or enzyme activities. Through phased induction of the small-molecular compounds, the differentiated cells can be differentiated into the chondrocytes, precision quality control can be achieved in eachstep, and standardization operation and large-scale production are facilitated. The method provided by the invention has wide donor sources, a patient himself can be used as a donor, and the chondrocytes needed for basic research, clinical treatment, or tissue engineering production can be obtained in a relatively short period of time.
