New, Exciting Techniques Delay Aging
As people live longer, there will inevitably be an increased need for joint replacements One of the major problems encountered by doctors is the fact that, although they have been able to replace joints for a number of years, they have been unable to replace worn-out or damaged cartilage.
In fact, if this problem were solved it would enable surgeons to delay joint replacement for a number of years. To know more about joint replacement you can visit https://curryorthopedics.com/.

According to the BBC, the University College London has been growing cartilage stem cells. In this technique, cells are harvested from the patient, grown in a lab, and then transplanted back into the patient after a joint replacement or to avoid this surgery for as long as possible.
Using the patient's own cells circumvents the need for patients to take immune-suppressant drugs for the rest of their lives. Cells grown from the patient's own cells also contained higher levels of collagen, the protein constituent of cartilage.
Limitations of the Method
The University College research was led by an Ear and Throat specialist, Dr Archana Vats, She explained that the main problem that led to the search for alternatives was the difficulty for the body to repair or grow new cartilage after injury.
The research involved growing human embryonic stem cells with chondrocytes or cartilage cells in Petri dishes in the lab in a specialized system that encouraged them to change into cartilage cells.
The process has been tested successfully on mice before being ready to test on humans.
