Fig. 2From: Sourcing of human peripheral blood-derived myeloid angiogenic cells under xeno-free conditions for the treatment of critical limb ischemiaAdherent cells sourced from PBMCs under XF/SF conditions enhanced endothelial sprouting. GFP-expressing endothelial cell spheroids were embedded within collagen I hydrogels with optional supplementation of cells sourced from PBMCs in various media and allowed to sprout for 1 day. A Phase contrast and fluorescent micrographs were taken at various locations and representative sprouting spheroids are highlighted in red circles. B Quantification of cumulative sprout length per spheroid cultured alone or in co-culture with PBMC-derived cells sourced in various media (n = 48)Back to article page
