Small Molecules Mediated Hematopoietic Stem And Progenitor Cells Expansion For Gene Editing Application
BLOOD(2018)
摘要
Genome editing of Hematopoietic stem Cells has revolutionized the treatment strategies for genetic disorders. Despite this, it still remains a great challenge as hematopoietic stem cells tend to lose its stem-ness during the ex vivo culture and gene editing process. The need for large dose of CD34+ HSPCs for manipulation makes it a seemingly difficult strategy. Recent works suggest that the potential effects of small molecules in expanding cord blood HSPCs ex vivo promoting self-renewal and delaying differentiation. We screened several reported small molecules to identify a condition that promotes the expansion of adult HSPCs for gene manipulation process.
