The science behind bony scutes is deep and it can only be understood by studying a fish right from its embryonic stage.
The scales or bony scutes that you see on the body of many fish are made up of dentine, a hard tissue also found in human teeth. However, do you know that fish ancestors were soft-bodied animals and didn’t have such hard, scaly armors to protect themselves?species? A team of researchers at Caltech recently published a study that attempts to answer this question in detail.
During their study, the researchers tagged different embryonic cells using fluorescent dyes and observed the migration of these cells under low-light conditions. They noticed that neural crest cells accumulated at the same spot in the embryo from where scutes were originating. Plus, when the researchers studied the gene expression profile of the osteoblast, they detected neural crest gene signatures. “The results definitively show that sterlet trunk neural crest cells give rise to osteoblasts of the scutes,” the researchersThus, the neural crest was a crucial evolutionary innovation driving the origin and diversification of dermal armor along the entire body axis.” They added.
