embryonic stem cells have immune rejection problems and the chance of forming teratomas
mesenchymal stem cells can:
form adipocytes, osteoblasts and chondrocytes
home to sites of injury and modify disease process
secrete cytokines and growth factors
manage chronic disease as they are potent immune regulators
it is difficult to get mesenchymal stem cells to liver as a cirrhotic liver has poor blood supply, and the stem cells can get trapped in the narrow vessels of the lungs causing thrombi
treatment with TGF influences them to go to the liver
