Full organs can be grown using stem cells, which can then be used to provide patients with organ transplants.
In therapeutic cloning, a cloned embryo is created to produce embryonic stem cells. These stem cells will grow into an organ that the patient’s body will not reject. This is because the embryo, and therefore the organ, will have the same DNA as the patient being provided with the organ.
Stem cells can also be injected into patients. This technique may be useful to treat conditions such as diabetes and paralysis. The stem cells divide to form differentiated replacement cells, which repair the damaged tissue.
Meristems are regions of undifferentiated cells typically found near the tips of stems and roots. These cells are capable of division and growth. Meristem tissue cuttings can be used to produce clones of plants quickly and economically. This means that rare or endangered plant species can be cloned, helping to preserve them.
Farmers can use meristem cells to clone plants with special features, like disease resistance, producing large numbers of genetically identical plants.
