OCR cells are among the newest progenitor cells to be defined in vertebrates.[38] The work generated wide interest and was described in prominent journals as a major breakthrough for understanding biology and for understanding diseases such as osteoporosis and osteoarthritis.[39][40] Mukherjee's team have shown that OCR cells can be transplanted into animals, and they can regenerate cartilage and bone after fractures.[4] With Daniel L. Worthley's team at the University of Adelaide and South Australian Health and Medical Research Institute they have been working on the translational cell-based research on osteoarthritis and cancer.[37][41]
