The latest Nature publication: Enhancement of the reconstitution capacity of cord blood-derived hematopoietic stem and progenitor cells!

 | Post date: 2021/07/16 | 
Cord blood (CB) represents a source of hematopoietic stem and progenitor cells (CB-HSPCs) for bone marrow (BM) reconstitution, but clinical CB application is limited in adult patients due to the insufficient number of CB-HSCPCs and the lack of effective ex vivo approaches to increase CB-HSPC functionality. human-induced pluripotent stem cells (hiPSCs) have been indicated as donor cells for bioactive extracellular vesicles (EVs) modulating properties of other cells. In this regard, The latest Nature publication introduced hiPSC-derived EVs (hiPSC-EVs) for the enhancement of the hematopoietic potential of CB-derived CD45dimLin-CD34+ cell fraction enriched in CB-HSPCs. The scientists demonstrated that hiPSC-EVs improved functional properties of CB-HSPCs critical for their hematopoietic capacity including metabolic, hematopoietic and clonogenic potential as well as survival, chemotactic response to stromal cell-derived factor 1 and adhesion to the model components of hematopoietic niche in vitro.
