Stem Cell Therapy in Progressive Liver Fibrosis: Una revisión completa
Liver fibrosis is a chronic condition characterized by the excessive accumulation of scar tissue in the liver, lo que lleva a deterioro de la función hepática y complicaciones potencialmente mortales. Stem cell therapy has emerged as a promising approach for treating liver fibrosis by harnessing the regenerative potential of stem cells. This review provides a comprehensive overview of the current understanding of stem cell therapy in progressive liver fibrosis.
Etiology and Pathogenesis of Liver Fibrosis
Liver fibrosis is primarily caused by chronic liver injury, which can result from various etiologies such as viral infections, abuso de alcohol, enfermedad del hígado graso no alcohólico, y trastornos autoinmunes. Hepatic stellate cells (HSC) are the primary mediators of fibrosis. Upon activation, HSCs undergo a phenotypic transformation into myofibroblasts, which produce and secrete excessive extracellular matrix (ECM) componentes, leading to the formation of fibrotic scars.
Papel de las células madre en la regeneración del hígado
Las células madre poseen la capacidad de autorrenovarse y diferenciarse en varios tipos de células.. en el higado, stem cells contribute to liver regeneration and repair. Two main types of stem cells involved in liver regeneration are mesenchymal stem cells (MSC) y células madre hepáticas (HSC). MSCs can differentiate into hepatocytes, colangiocitos, y otros tipos de células hepáticas, while HSCs give rise to hepatocytes.
Mesenchymal Stem Cells for Fibrosis Treatment
MSCs have shown promise in treating liver fibrosis. They can inhibit HSC activation and proliferation, promover la regeneración de hepatocitos, y modular la respuesta inmune. Preclinical studies have demonstrated that MSCs can reduce fibrosis and improve liver function in animal models of liver disease. Clinical trials are currently underway to evaluate the safety and efficacy of MSC therapy in patients with liver fibrosis.
