Abstract

The invention discloses the use of an asiatic acid derivative for promoting the proliferation of human adipose-derived mesenchymal stem cells in vitro and maintaining stemness. It was found that asiatic acid, 2,3-dicarbonyl-23-carboxy n-butyl ester-ursane-12-ene-28-carboxylate ethyl ester, 2,3-dicarbonyl-23-carboxy isobutyl ester- The effects of ethyl ursane‑12‑ene‑28‑carboxylate on human adipose-derived mesenchymal stem cells are common and different. All three can significantly promote the proliferation of human adipose-derived mesenchymal stem cells in vitro, but asiatic acid in While promoting the proliferation of human adipose-derived mesenchymal stem cells in vitro, it can promote its chondrogenic differentiation, which is suitable for the application of human adipose-derived mesenchymal stem cells in chondrogenic formation, while 2,3-dicarbonyl-23-carboxy n-butyl ester-ursane- Ethyl 12-ene-28-carboxylate and ethyl 2,3-dicarbonyl-23-carboxylate-ursane-12-ene-28-carboxylate can promote the proliferation of human adipose-derived mesenchymal stem cells in vitro While maintaining its stem cell characteristics, it is suitable for the rapid expansion of human adipose-derived mesenchymal stem cell seed cells in vitro.

Description

technical field [0001] The invention belongs to the field of biology, and relates to in vitro culture and expansion of adipose-derived mesenchymal stem cells, in particular to an application of asiatic acid derivatives for promoting in vitro proliferation of human adipose-derived mesenchymal stem cells and maintaining stemness. Background technique [0002] Adipose-derived mesenchymal stem cells (ADSCs) are a kind of stem cells with multi-directional differentiation potential isolated from adipose tissue, which can be induced to differentiate into fat, bone, cartilage, pancreatic β-cells and cardiac muscle under specific conditions. cell. [0003] In recent years, ADSCs have significantly increased each year in tissue repair and regeneration research. Researchers are most concerned about the number of ADSCs used in repair and regeneration, clinical trials evaluating efficacy and safety. According to the US Clinical Trials (2015) report, there are 121 studies registered usi...
