Comparison of the Effects of Different Cryoprotectants on Stem Cells from Umbilical Cord Blood

Figure 3

(a) The colonies were observed in an inverted microscope. CFU-GEMM is full of the immature nucleated red blood cells and granulocytes from the center to the edge of clone and two CFUs of GEMM were showed in group A. BFU-E are red and were shown in group B. CFU-GM is almost transparent and BFU-E and CFU-GM were shown in group C. There was almost no colony formation in group D. (b) The CFU of group C was higher than that of group A () and groups B, D () after thawing. Scale bars: 100 μm.
