Areas of expertise Osteoarthritis is a disease characterised by loss of joint cartilage. By gaining a better understanding of the process by which this happens we hope to identify targets that could ...

but it had previously been recognized that horseshoe crabs have cartilage-like tissues. The team were able to isolate an enhancer for these animals and popped it in zebrafish, turning up the ...
