However, increasing evidence suggests that BM-MSCs can also undergo somatic mutations and give rise to tumors in vivo.This report aims to study the phenomenon of in vivo mutation-induced tumorigenesis in BM-MSCs and the related isolation and biological characteristics of tumor stem cells. We will use flow cytometry and tumor stem cell-specific markers (CD24 and CD44) to isolate the tumor stem cells in BM-MSCs. Meanwhile, we will evaluate the biological characteristics of these tumor stem cells using in vitro culture and tumor formation assays.This research will help to better understand the potential tumorigenic risks of BM-MSCs and provide new ideas and methods for stem cell therapy in cancer treatment.Keywords: bone marrow mesenchymal stem cells; in vivo mutation-induced tumorigenesis; tumor stem cells; biological characteristics; stem cell therapy.
