Immunohistochemical characterization of hepatic progenitor cells in chronic hepatitis B patients;

PartⅠWnt/β-Catenin Signaling Mediates Progenitor Cells Activation in Rodents Adult hepatic progenitor cells (oval cells) are facultative stem cells in the liver that are activated during regeneration only during inhibition of innate hepatocyte proliferation.

Hepatic stem cells are a group of cells in liver that have the self-renewal capability and multi-differentiation potential,including oval cells,small hepatocytes and small hepatocyte-like progenitor cells.

It binds with DNA or interacts with other protein to regulate the transcription of target gene,promote the tumor growth,cell adhesion(to resist apoptosis),the differentiation of progenitor cells.

Recently,stem cells such as retinal stem cells(RSC),mesenchymal stem cells(MSC),embryonic stem cells(ESC),brain-derived stem cells(BDSC),also the cells such as retinal progenitor cells,retinal precursor cells,retinal epithelium(RPE) and Müller cells have been widely concerned in studying of retinal repairment and retinal regeneration.
