medicine that will do this, they have grown stem cells in labs and then injected them into patients. Scientists have built on the technology for bone marrow transplants and they have been looking at embryonic stem cells and induced pluripotent stem cells, which can both give rise to any type of cell in the body. They both live indefinitely in cultures where the scientists have looked at them, after giving them signaling molecules, and see what type of cells they are. Tissue engineers have been working on patches to repair heart tissues in humans. While in animals, they have been trying to grow whole hearts, livers, and kidneys. This shows that stem cells help animals fix their bodies if they are injured or damaged somehow. Stem cells can also be used in gene therapy.
Scientists have been developing a new type of gene therapy. First, the cells from a patient with a genetic disorder were isolated, and then they created induced pluripotent cells. Then they replaced the defective gene with a functional copy. The cells were then differentiated and put back into the patient. This technique has worked in mice to treat sickle cell anemia, and scientists have hoped that it would also work in humans. Stem cell transplants into spinal cords have also shown promise. This shows that stem cells can help regenerate new nerve cells in the spinal cord area, which could help with faster healing for those who have been in sever accidents. For example, in rats who had spinal…
