Regulators of liver cancer stem cells

Hepatocellular carcinoma(HCC)is a leading cause of cancer deaths.It is often detected at a stage when there are few therapeutic options.Liver cancer stem cells(LCSCs)are highly tumorigenic and resistant to chemotherapy and radiation therapy.Their presence in HCC is a major reason why HCC is difficult to treat.The development of LCSCs is regulated by a variety of factors.This review summarizes recent advances on the factors that regulate the development of LCSCs.Due to the importance of LCSCs in the development of HCC,a better understanding of how LCSCs are regulated will help to improve the treatments for HCC patients.
