Popis: Stem cells exist and maintain their quiescence and pluripotency in stem cell niche. Here, we hypothesized that regulation of cell-cell interactions using a polymeric scaffold as synthetic extracellular matrix (ECM) could be critical in creating a hematopoietic stem cell (HSC) niche in vitro. Angiopoietin-1 (Ang1) binds to the tyrosine kinase receptor (Tie2), and regulation of the Tie2/Ang1 interaction is important in maintaining the quiescence of HSCs in vivo. Alginate hydrogel was thus modified with Ang1 as a synthetic ECM to mimic the HSC niche. Long-term HSCs (CD34
