Stem cell therapy for liver fibrosis in chronic cases

Stem Cell Therapy for Liver Fibrosis in Chronic Cases

Liver fibrosis is a chronic and progressive condition characterized by the excessive deposition of extracellular matrix (ECM) in response to chronic liver injury. It can lead to cirrhosis and end-stage liver disease, necessitating liver transplantation. Stem cell therapy has emerged as a promising therapeutic approach for liver fibrosis, hastalık modifikasyonu ve rejenerasyon potansiyeli sunan.

Etiology and Pathogenesis of Liver Fibrosis

Liver fibrosis is caused by various chronic liver diseases, including viral hepatitis, alkolsüz yağlı karaciğer hastalığı (NAYKH), and autoimmune hepatitis. Hepatic stellate cells (HSC'ler) play a central role in the fibrotic process. In response to liver injury, HSCs become activated and differentiate into myofibroblasts, which produce excessive ECM components, leading to fibrosis.

Role of Stem Cells in Liver Regeneration

Stem cells have the capacity for self-renewal and differentiation into various cell types. Karaciğerde, stem cells are present in the canals of Hering and the bone marrow. These cells can differentiate into hepatocytes and cholangiocytes, the functional cells of the liver, Karaciğer yenilenmesine katkıda bulunmak.

Preclinical Models of Liver Fibrosis and Stem Cell Therapy

Animal models of liver fibrosis have been used to evaluate the therapeutic potential of stem cell therapy. Studies have shown that bone marrow-derived stem cells (BMSC'ler) can migrate to the injured liver, differentiate into hepatocytes and cholangiocytes, ve fibrozu hafifletmek. BMSCs have also been found to inhibit HSC activation and promote ECM degradation.
