Can stem cell transplantation and gene editing treat gene defects?

Stem cell transplantation and gene editing technology are both new therapies that have attracted much attention at present. They can treat some diseases with gene deletion to some extent, but they can't cure all gene-related diseases.

Stem cell transplantation can be used to treat genetic defects, such as albinism and chondromalacia. Stem cell transplantation refers to replacing the missing cells in patients' own liver, lungs, kidneys and other important tissues and organs to some extent, thus alleviating or eradicating the symptoms of patients. However, there are some potential risks in stem cell transplantation, such as chemotherapy before infusion and high probability of malignant tumor after bone marrow extraction.

As for gene editing technology, although it can change human genes more directly and accurately, thus potentially curing some human diseases, it is still in the primary stage, and there are many technical, moral and safety problems to be solved. At the same time, even if the technical problems of gene editing technology can be solved, the technology involving human genes is also facing severe ethical and legal challenges.

To sum up, although stem cell transplantation and gene editing technology are very cutting-edge gene therapy methods, there are still scientific and technological problems and serious ethical and social problems in the treatment of some gene-related diseases, which need to be gradually popularized under extensive discussion and supervision.
