MicroRNA-29b-1 is involved in self-renewal and fate decisions of human osteosarcoma 3AB-OS cancer stem cells

Emerging evidence suggests that treatments targeting cancer stem cells (CSCs) within a tumor can halt cancer and improve patient survival. Moreover, identification of CSC-related MicroRNAs (miRNAs) would provide information for a better understanding of CSCs. miR-29 family is a class of miRNAs aberrantly expressed in multiple cancers. They are frequently down-regulated in osteosarcoma (OS), the most common form of childhood cancer with a potent metastasizing potential. 3AB-OS CSC, a human pluripotent CSC line by us produced from the human osteosarcoma MG63 cells (1) is a useful model to study CSC origin and roles (2). Previously, we have shown that in 3AB-OS CSCs miR-29b is potently down-re…
A short story of 3AB-OS Cancer Stem Cells, a possible model for studying cancer stemness

All tumors contain a population of Cancer Stem Cells (CSCs) responsible for the initiation, growth and development of the tumor and a challenge in cancer research is their identification and eradication. In our laboratory, by chemical treatment of the human osteosarcoma MG63 cell line, we have isolated and characterized the human OS CSC line (3AB-OS). 3AB-OS CSCs have a significant chromosomal complexity and a large number of molecular abnormalities which appear to be strongly congruent with those described in a large number of pediatric and adult osteosarcomas. 3AB-OS cells transdifferentiated in vitro into cells of all three primary germ layers and, when xenografted in athymic mice they w…
