A patient has been diagnosed with type 1 diabetes. The nurse realizes that this patient might benefit from which of the following genetic technologies?
1. Stem cell therapy
2. Microarray analysis
3. Real-time PCR
4. Gene therapy
Stem cell therapy
Rationale:
Stem cells are unspecialized cells that have the potential to divide without limit and to develop into specialized cells such as insulin-producing cells of the pancreas. Microarray analysis is primarily used in the research setting, specifically in the area of cancer prognosis and treatment stratification. Real-time PCR is an emerging technology that allows for the detection and quantification of a small fragment of replicating DNA during the amplification process and offers rapid and sensitive quantification of the gene of interest. Gene therapy is the correction of a genetic mutation by the introduction of DNA into a cell as a treatment modality to improve the patient's health.
