WebIn both models, PTN increased survival by accelerating the recovery of BM hematopoietic stem and progenitor cells in vivo. PTN treatment promoted HSC regeneration via activation of the RAS pathway in mice that expressed protein tyrosine phosphatase receptor-zeta (PTPRZ), whereas PTN treatment did not induce RAS signaling in PTPRZ-deficient mice ... WebThe definition of hematopoietic stem cell has developed since HSCs were first discovered in 1961. The hematopoietic tissue contains cells with long-term and short-term regeneration capacities and committed multipotent, oligopotent, and unipotent myeloid tissue. HSC transplants are used in the treatment of cancers and other immune system disorders.

Web6 jun. 2024 · It is intriguing to consider how two lipids through different immediate actions can elicit the same overall phenotype, i.e., a net positive effect on HSC regeneration. PGE 2 is likely acting directly on the HSPCs by enhancing long-term engraftment. It will be interesting to similarly identify a target cellular population of EETs. Web30 mrt. 2024 · Yi et al. reveal a role of NO-induced protein S-nitrosylation in HSC regeneration. Deficiency of GSNOR, a denitrosylase, causes HSC reconstitution decrease, which is restored by NO inhibition, TCA treatment, or Chop deletion. The findings link S-nitrosylation, protein aggregation, and cellular viability in HSC during blood regeneration.
