PROM1 and liver cancer: Initially, the characterisation of liver CSCs focussed also in liver cancer on the identification of general CSC markers such as CD24,37 CD4438 and CD133,39 while CK19 was also reported to serve as a relatively specific marker of liver CSCs.36 In our study, the malignant tumours developed in the liver showed high and significant expression of CD24, CD44 and CD133 when compared to miPSCs.
