網頁Rac GTPases form part of the family of Rho small GTPases. Rac GTPases, like other Rho family GTPases, are key molecular switches controlling the transduction of external signals to cytoplasmic and nuclear effectors. The development of genetic and pharmacological tools has allowed a more precise defi … Haematopoietic stem cells (HSCs) Haematopoietic stem cells (HSCs) reside in the medulla of the bone (bone marrow) and have the unique ability to give rise to all of the different mature blood cell types and tissues. HSCs are self-renewing cells: when they differentiate, at least some of their daughter cells remain … 查看更多內容 Haematopoiesis is the formation of blood cellular components.
