Abstract
Described in the present application are methods for preparing populations of hematopoietic stem cells (HSCs), e.g., autologous and/or allogenic HSCs, using mechanical stretching or Trpv4 agonisists, and methods of use of the HSCs in transplantation. In some embodiments, the methods include providing a population comprising hemogenic endothelial (HE) cells, and (i) contacting the HE cells with an amount of an agonist of transient receptor potential cation channel-subfamily vanilloid member 4 (Trpv4); and/or (ii) subjecting the cells to cyclic 2-dimensional stretching, for a time and under conditions sufficient to stimulating endothelial-to-HSC transition. Also provided herein are methods for treating subjects who have, bone marrow, metabolic, and immune diseases; the methods include administering to the subject a therapeutically effective amount of hematopoietic stem cells (HSCs) obtained by a method described herein.
