Viability and fold increase in total nucleated cells of expanded umbilical cord blood-derived hematopoietic stem and progenitor cells after 7 days of co-culture with mesenchymal stromal cells from different sources. AT, adipose tissue; BM, bone marrow; FBS, fetal bovine serum; FI, fold increase; FL, feeder layer; HPL, human platelet lysate; TNC, total nucleated cells; UCM, umbilical cord matrix. Values are presented as mean ± SEM. n = 3 for all conditions, with exception of ‘NO FL’: n = 2. **p < 0.01; *p < 0.05
