  • Use of polysaccharides in promoting proliferation and differentiation of female germline stem cells
    Patent number: 11827901
    Abstract: Use of Cistanche deserticola polysaccharide (CDP) in promoting the proliferation and differentiation of female germline stem cells (FGSCs) is provided. Specifically, the addition of CDP in an in vitro cultivation system can promote the proliferation and differentiation of FGSCs, and especially can enhance the in vitro directed differentiation of FGSCs into oocytes, which provides a new research reference for studying the generation of oocytes in vivo and in vitro and also brings a new hope for research on physiological infertility.
