We have heard a lot recently about how stem cells can be used to help patients who would typically require the implantation of an artificial joint such as a hip or knee. Using one of these methods, doctors are able to remove bone marrow from the patient and use the stem cells in the bone marrow to attempt to regrow bone tissue and joint material inside the patient. While this method may work, it is only one method doctors are using with stem cells, but there are others.
In a recent news feature form HNGN, doctors are now using stem cells to regrow cartilage in a laboratory and then implant that it into the patient. Since the cartilage was grown using the patient’s own stem cells, the new cartilage will have the same DNA as the patient. This should mean that the body will not see the new cartilage as a foreign substance, so there should be no risk of rejection, which is always a major risk in an organ transplant or event the implanting of an artificial joint like a knee or hip.
