Explanation:

1.Stem cells are special human cells that are able to develop into many different cell types. This can range from muscle cells to brain cells

2. Gene therapy is designed to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.

3.Gene therapy does have risks and limitations. The viruses and other agents used to deliver the "good" genes can affect more than the cells for which they're intended. If a gene is added to DNA, it could be put in the wrong place, which could potentially cause cancer or other damage.

4.Clinical trials of gene therapy in people have shown some success in treating certain diseases, such as: Severe combined immune deficiency. Hemophilia. Blindness caused by retinitis pigmentosa.

5. Few Examples Are:

Engineered Natural Killer Cells against Hodgkin's Lymphoma.  Pectic Acid-based Corning Dissolvable Microcarriers for Cell Therapies. Development of Cell Expansion Systems for Gene-edited Blood and Immune Cells. Microsoft's AI Tool for Fine Tuning CRISPR.
