neural crest cells are embryonic cells that pinch off early in development to form a variety of structures 神经嵴细胞是胚胎发育早期形成各种组织的胚胎细胞。
In the new study, the researchers found snippets of genetic material associated with neural crest cells in the electroreceptors 负责完成的,具体研究结果被发表在日前出版的进化与发展杂志上。
Using molecular tests, they found two independent genetic markers of neural crest cells in the sharks " electroreceptors 通过分子测试,他们在鲨鱼的电感受器中发现了神经嵴细胞的两种独立基因标志。
The finding suggests that neural crest cells migrate from the sharks " brains to various regions of the head, where they develop into electroreceptors 这一发现说明,神经嵴细胞从鲨鱼的脑部移至其头部的各个区域,并在其头部发育为电感受器。
In the new study, the researchers found snippets of genetic material associated with neural crest cells in the electroreceptors . they did not dye the neural crest cells and trace their development 这项研究是由美国佛罗里达大学的马丁科恩和其实验室负责完成的,具体研究结果被发表在日前出版的进化与发展杂志上。

"it still requires a definitive experiment, where the developing neural crest cells are marked with dye, the embryo develops and the dye clearly shows up in the electroreceptors, " northcutt said 美国其他一些研究者认为这个发现非常有意思,但是要想在鲨鱼神经嵴细胞与电感受器之间建立直接联系,还需要进行更多的研究。
Glenn northcutt, a neuroscientist at the university of california, san diego, who was not involved in the study, said the finding was interesting, but that more studies are needed before a direct link between neural crest cells and electroreceptors can be established 美国其他一些研究者认为这个发现非常有意思,但是要想在鲨鱼神经嵴细胞与电感受器之间建立直接联系,还需要进行更多的研究。这项研究是由美国佛罗里达大学的马丁科恩和其
