Gene and stem cell therapy: alone or in combination?
1Department of Neurology, Jefferson Medical College, Philadelphia, Pennsylvanian 19107, USA.
Introduction:
Both gene and stem cell therapies hold great promise in the treatment of many genetic diseases and are currently focus of interest for many investigators. While both approaches are offering great and valuable treatment options for devastating and life-threatening diseases, they hold much greater promise in combination.
Methods:
As there are multiple options in selecting gene transfer vehicles among the non-viral and viral vectors, there are also many options among the different transplantable cell types ranging from lineage-restricted progenitor cells to multipotent and pluripotent stem cells. Here, combination of the gene therapy and stem cell therapy is discussed.
Results:
Several suc-cessful gene and stem cell therapies have been reported both in animal and human trials. Combination of the gene therapy and stem cell therapy can be carried out sequentially where the cell transplantation and the in vivo gene therapy are accomplished one after the other; or, as it is more commonly practiced, they can be carried out as ex vivo gene therapy where the transplantable cells are genetically modified outside the body before being transplanted into the body.
Conclusion:
The combination of the stem-cell technology with gene therapy has the potential of providing both regenerative tissue and therapeutic material simultaneously; therefore, having the benefits of both technologies.
Insights
Combining gene therapy and stem cell therapy offers a powerful approach for treating genetic diseases. This combined strategy provides both regenerative tissue and therapeutic benefits, enhancing treatment outcomes.
Area of Science:
- Regenerative Medicine
- Genetic Therapy
Background:
- Gene therapy and stem cell therapy are promising treatments for genetic diseases.
- Investigational interest is high for both therapeutic modalities.
- Combining gene and stem cell therapies offers enhanced potential for treating severe diseases.
Purpose of the Study:
- To discuss the combination of gene therapy and stem cell therapy.
- To explore the various options for gene transfer and cell transplantation.
- To highlight the synergistic benefits of combining these two therapeutic approaches.
Main Methods:
- Review of existing literature on gene and stem cell therapies.
- Discussion of sequential and ex vivo combination strategies.
- Consideration of different cell types, including progenitor and pluripotent stem cells.
Main Results:
- Successful gene and stem cell therapies have been demonstrated in animal and human trials.
- Combination therapies can be administered sequentially (in vivo gene therapy followed by cell transplantation) or ex vivo (genetic modification of cells before transplantation).
- Ex vivo gene therapy is a commonly practiced method.
Conclusions:
- The integration of stem cell technology and gene therapy can simultaneously provide regenerative tissue and therapeutic material.
- This combination leverages the advantages of both distinct technologies.
- This approach holds significant potential for treating a range of genetic disorders.
