CDC42 plays a critical role in maintaining hematopoietic niche homeostasis, particularly under stress conditions like 5FU treatment and stem cell transplantation. Overactivation of CDC42 disrupts F-actin fiber orientation, mitochondrial function, and autophagy/mitophagy in mesenchymal stem and progenitor cells, leading to bone marrow (BM) failure, increased senescence, and reduced bone volume. Therefore, pharmacological attenuation of CDC42 can act as a potential therapeutic target for diseases associated with BM failure, hematopoietic dysfunction and osteoporosis.
