[Development of hematopoietic stem cell-targeted gene therapy].
Hematopoietic stem cell (HSC)-targeted gene therapy is curative for various genetic blood diseases, and its efficacy has been demonstrated in recent clinical trials. HSCs have self-renewal and hematopoietic multipotency; therefore, repairing pathological mutations or defects in HSCs allows for a lifelong cure with a single treatment. Autologous HSC gene therapy has been developed by lentiviral gene addition or gene editing, and is an option for most patients because it does not require a compatible donor. Current HSC gene therapy is based on ex vivo methods, in which patient HSCs are harvested, genetically modified ex vivo, and autologously transplanted into patients. However, the complexity of this process and the high cost of treatment are hindering the spread of gene therapy. Therefore, in vivo HSC gene therapy is being developed to deliver gene therapy tools directly into bone marrow HSCs by administration without ex vivo culture.
