摘要
Hematopoietic stem cells(HSCs)are critical for the treatment of a variety of hematological diseases.However,the low number of HSCs lead to the clinical application difficult.To gain more functional human HSCs ex vivo,Sakurai et al.established a recombinant-cytokine-free and albumin-free culture system,i.e.PCL-PVAc-PEG-based culture,in combination with 740Y-P,butyzamide and UM171,to improve the long-term expansion of human cord blood HSCs.
