Stellate cells are mesenchymal stem cells

چکیده
Background Vitamin A-storing hepatic stellate cells (HSC) are mainly known for their contribution to fibrogenesis in chronic liver disease, but their identity and function in normal liver remained unclear. Since HSC possess stem/ progenitor cell characteristics [1] their contribution to stem cell-associated functions in the liver was investigated. Stem cell functions in the liver were reported during fetal hematopoiesis and tissue repair after severe injury when the proliferation of hepatocytes is impaired. By using several in vitro and in vivo approaches evidence was provided that stellate cells represent mesenchymal stem cells (MSC), which can support hematopoietic stem/progenitor cells in the fetal liver and contribute to the regeneration of injured liver as multipotent adult stem cells.

Stem cells are a good alternative for regenerative medicine because of their characteristics such as self-renewal and differentiation potential. They are classified into different types of stem cells including embryonic stem cells, induced pluripotent stem cells, multipotent stem cells, and ultimately uni-potent stem cells. Mesenchymal stem cells extracted from adult tissues. Due to the lack of...
