RESUMEN
Hematopoietic stem cell (HSC) gene therapy has shown potential as a therapeutic approach for thalassemia in recent years. However, a comparison of the varying gene therapy methods of HSC gene therapy in thalassemia has never been reviewed. This study aims to evaluate the utilization of HSC gene therapy approaches in animal models of thalassemia. A systematic review was conducted in five databases: PubMed, EBSCOHost, Science Direct, SCOPUS, and Proquest using a combination of the terms hematopoietic stem cell or hematopoietic stem cell or HSC, thalassemia, genetic therapy or gene therapy and animal model. Only journals published in English between 2008 and 2023 were included. This literature included six studies analyzing the use of HSC gene therapy in thalassemic mice models. The three outcomes being assessed in this review were globin levels, hematological parameters, and red blood cell (RBC) phenotypes. Gene therapy approaches for thalassemia using HSC showed significant improvement in ß-globin levels and RBC phenotypes. Phenotypic improvements were also observed. These outcomes indicate good efficacy in gene therapy for thalassemia in mice models. Furthermore, more studies assessing the efficacy of HSC gene therapy in the human model should be done in future studies.
