Summary
Skin gene transfer using in vivo electroporation effectively delivered erythropoietin (Epo) in rats. This method achieved sustained Epo expression and increased hematocrit levels with minimal, transient skin damage.
Area of Science:
- Biotechnology
- Dermatology
- Molecular Biology
Background:
- The skin offers accessible target for gene transfer.
- Previous studies demonstrated long-term erythropoietin (Epo) delivery via muscle-targeted gene transfer using in vivo electroporation.
Purpose of the Study:
- To investigate the efficacy of in vivo electroporation for skin-targeted gene delivery.
- To optimize gene transfer parameters for erythropoietin (Epo) delivery in rat skin.
Main Methods:
- Intradermal injection of plasmid DNA expressing rat erythropoietin (pCAGGS-Epo) in rats.
- Testing three electrode types and varying voltages for skin-targeted gene transfer.
- Assessing Epo gene expression, duration, and hematological effects.
Main Results:
- Plate-and-fork electrodes were effective for Epo delivery at low voltages (12–24 V).
- Epo gene expression was localized to the injection site, dose-dependent, and persisted for 7 weeks.
- Increased hematocrit levels were observed for 11 weeks, with transient skin damage resolving within 7 days.
Conclusions:
- Skin-targeted gene transfer using in vivo electroporation is a viable method for Epo delivery.
- The procedure is effective for short-term Epo delivery with manageable side effects.
- Optimized low-voltage electroporation facilitates efficient gene transfer in the skin.

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.
00:59Gene Therapy
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be inserted. The...
