Morphology and isolation success of mesenchymal stem cells (MSCs) from human umbilical cord blood (hUCB).
(A) Phase-contrast microscopy of adherent UCB-MSCs in culture (magnification ×10). (B) Correlation between collected volume and successful (fibroblastic cells able to form colonies) or unsuccessful (cells not able form colonies) isolation of UCB-MSCs. Data are presented as box plots. Individual outlying data points are shown as filled circles (⚫). Statistically significant differences between the unsuccessful and successful isolation of cells were determined using the Mann-Whitney U test. *Indicates statistically significant differences (***p < 0.001).
