Anti-Aging Remedy for Stem Cells

1 Fountain of Youth for Blood Stem Cells Found

Results from a study in mice show that by inhibiting the Cdc42 protein, older hematopoietic stem cells (HSCs) behave like younger ones. HSCs are made in the bone marrow and eventually become red and white blood cells and platelets. While the number of HSCs increase with age, their ability to create new blood and immune cells become impaired, putting older individuals at a greater risk for developing infections and diseases such as leukemia. Researchers inhibited Cdc42 with drugs and were surprised that the aging process reversed in HSCs, something they previously thought was impossible. Future studies will involve using a protein inhibitor in mice along with gathering human HSCs for experiments to see if the results in mice apply to humans.
