Fig. 2From: Lack of tumorigenesis and protumorigenic activity of human umbilical cord mesenchymal stem cells in NOD SCID miceChanges in nodule growth after hUC-MSC inoculation. A Graph of nodule growth in the hUC-MSC1 group after treatment. Compared with the negative control group, the hUC-MSC1-P5, hUC-MSC1-P7, and hUC-MSC1-P10 groups showed no significant difference in nodule growth. B Graph of nodule growth in the hUC-MSC2 group after treatment. Compared with the negative control group, the hUC-MSC2-P5, hUC-MSC2-P7, and hUC-MSC2-P10 groups showed no significant difference in nodule growthBack to article page
