Fig. 1From: Influence of the mesenchymal stromal cell source on the hematopoietic supportive capacity of umbilical cord blood-derived CD34+-enriched cellsSchematic representation of the experimental design. Umbilical cord blood CD34+ cells were expanded in a co-culture system using a mesenchymal stromal cell (MSC) feeder layer (FL) from different sources for 7 days. MSC were previously expanded using medium with either FBS or HPL. UCB cells were characterized by immunophenotyping and in vitro clonogenic assays. AT, adipose tissue; BM, bone marrow; FBS, fetal bovine serum; FL, feeder layer; HPL, human platelet lysate; TNC, total nucleated cells; UCM, umbilical cord matrixBack to article page
