Tumor tissue in vitro weight comparison histogram. (A, B) In the second and third weeks, the tumor weight of human mesenchymal stem cell (hMSC) engraftment groups was significantly lower than that of control groups (P <0.01). (C, D, E) In the fourth, fifth and sixth weeks, the difference in tumor weight before and after hMSC intervention was not statistically significant between groups (P >0.01).
