Abstract

A recent study published in the journal Sciencemag.org has found that synovial joints, which are responsible for mobility and are commonly affected by arthritis, actually evolved in the ancestor of both cartilaginous and bony fish. Previously, it was believed that these joints only existed in land animals. The researchers studied the development of joints in skate embryos and found that they expressed the same genes as their bony counterparts, producing molecules used in arthritis treatments. This research may lead to better treatments for joint problems in humans. [Extracted from the article]
