Figure 4

Inoculation of htMSCs in tumor-bearing mice. (a) Images show G3, G4, and G5 lungs (macroscopically and microscopically), in comparison with normal control (normal mice lung) 20 days after tumor cell inoculation. One representative animal of each group is shown. (b) Pulmonary tissue-free measurements, showing that lungs were preserved in G4 group (2 htMSCs injections), similar to normal controls, represented as tumor- and inflammation-free area.
