Cord blood mononuclear cells were obtained from fresh cord blood units (<24 hrs old) via density gradient centrifugation over Ficoll-Paque™.
CD34+ cells were isolated using an autoMACS® Pro Separator after immunomagnetic labeling with CD34 microbeads. CD34+ cells were either immediately seeded onto substrates or cryopreserved, thawed, and then seeded.
Cells were seeded at a density of 1,000 cells/mL and cultured in Arteriocyte’s serum-free medium and growth factor cocktail.
