Embodiment 1

[0029] Example 1: Discovery of markers predicting the potential of bone marrow mesenchymal stem cells BMSCs to differentiate into cardiomyocytes

[0030] 1. Experimental basis (inducers: 5-azacytidine, angiotensin II, dimethyl sulfoxide)

[0031] 5-azacytidine [Li Xue et al., Experimental study on the differentiation of rat bone marrow mesenchymal stem cells into cardiomyocytes induced by 5-azacytidine, Heart Journal 2004, 15(6)], angiotensin II [Shi Jingbao et al. Different concentrations of angiotensin Ⅱ induce the directed differentiation of bone marrow mesenchymal stem cells into cardiomyocytes, China Tissue Engineering Research Vol. Differentiation of Stem Cells into Cardiomyocytes, Chinese Tissue Engineering Research Volume 20, Issue 1] is a well-recognized inducer in the field that can induce bone marrow mesenchymal stem cells BMSCs to differentiate into cardiomyocytes. Therefore, in this example, these three substances were selected as inducers, and the differential m...

Abstract

The invention discloses markers, a reagent and a reagent box for indicating the directional differentiation potential of mesenchymal stem cells (MSCs), in particular to markers, a reagent and a reagent box for indicating the potential that bone mesenchymal stem cells (BMSCs) directionally differentiate into cardiomyocyte-like cells. The makers are composed of alpha-oxoglutarate, dihydroxyacetone phosphate, asparagines and arachidonic acid. Results prove that the alpha-oxoglutarate, the dihydroxyacetone phosphate, the asparagines and the arachidonic acid are quite high in united indicating value, can be used as the markers for indicating the potential that the BMSCs differentiate into cardiomyocytes, and are high in efficiency when used for high throughput screening of inducers capable of inducing the BMSCs to differentiate into the cardiomyocytes, and people do not need to wait for several weeks to know an induction result.

Description

technical field [0001] The invention belongs to the field of stem cells, and relates to markers, reagents and kits for predicting the directed differentiation potential of mesenchymal stem cells. Background technique [0002] Mesenchymal stem cells (MSCs) are a kind of multipotent adult stem cells, which exist in many kinds of tissues during human body generation and development. In the mid-1970s, Friedenstein et al [Friedenstein A J, Gorskaja J F, Kulagina N N. Fibroblast precursors in normaland irradiated mouse hematopoietic organs. Exp Hematol, 1976,4(5):267-274] obtained a small number of energy from bone marrow. Adherently growing cells, which can differentiate into osteogenic or chondrogenic deposits, are believed to be the first demonstration of the existence of MSCs. At present, MSCs have been isolated from various mesenchymal tissues of adults, and these cells can be expanded in vitro and differentiated into various connective tissue cells such as bone, cartilage, ...
