Answer
Mukherjee's discovery of bone- and cartilage-forming stem cells has significant implications for regenerative medicine. These stem cells, found in bone marrow, have the potential to differentiate into various types of bone and cartilage cells, offering new possibilities for treating conditions such as osteoporosis and osteoarthritis. By understanding the mechanisms that control the differentiation and function of these stem cells, researchers can develop novel therapies to promote tissue repair and regeneration.
