Mouse embryonic stem cells (ESCs) are widely used in vitro stem cells, especially in cell therapy. This experiment aims to explore whether L-Wnt3a cells and their conditioned medium can promote the proliferation and differentiation of mouse embryonic stem cells. ESCs were extracted from mouse embryos and cultured in two different media to observe cell proliferation, pluripotency/differentiation markers, and cell morphology to analyze the effects of L-Wnt3a cells and their culture media on the differentiation and proliferation of mouse embryonic stem cells. The results showed that L-Wnt3a cells and their conditioned medium can promote the self-renewal and differentiation of mouse embryonic stem cells and maintain the pluripotency of stem cells.【Keywords】Mouse embryonic stem cells; L-Wnt3a cells; conditioned medium; self-renewal; differentiation
