Abstract
Liver fibrosis, is one of big problems usually ends with cirrhosis which considered a life threatening disease as the only way of treatment is the liver transplantation, this study aimed to find a new way for fibrosis treatment by the use of bone marrow isolated Mesenchymal stem cells (MSCs). Thioacetamide (TAA) was used for fibrosis induction in male Sprague Dawely (SD) rats which divided into two random groups: group infused with TAA for fibrosis induction and group as control negative group. MSCs were isolated from bone marrow of twenty five (4–5) weeks male SD rats, and labeled with fluorescent material (PKH26) to confirm the homing of cells. After fibrosis induction, rats were divided into four subgroups to study the effect of MSCs injection in fibrosis treatment. After 4 weeks from MSCs administration, all rats were sacrificed. Liver tissue were collected for histopathological and immunohistopathological studies. In comparison with control groups, the treated groups with MSCs showed improvement in the amount of deposited collagen which decreased compared to control positive group. So MSCs can be used to replace liver transplantation in the treatment of fibrosis.
