neural crest cells are embryonic cells that pinch off early in development to form a variety of structures 神經(jīng)嵴細胞是胚胎發(fā)育早期形成各種組織的胚胎細胞。
In the new study, the researchers found snippets of genetic material associated with neural crest cells in the electroreceptors 負責完成的,具體研究結果被發(fā)表在日前出版的進化與發(fā)展雜志上。
Using molecular tests, they found two independent genetic markers of neural crest cells in the sharks " electroreceptors 通過分子測試,他們在鯊魚的電感受器中發(fā)現(xiàn)了神經(jīng)嵴細胞的兩種獨立基因標志。
The finding suggests that neural crest cells migrate from the sharks " brains to various regions of the head, where they develop into electroreceptors 這一發(fā)現(xiàn)說明,神經(jīng)嵴細胞從鯊魚的腦部移至其頭部的各個區(qū)域,并在其頭部發(fā)育為電感受器。
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 這項研究是由美國佛羅里達大學的馬丁科恩和其實驗室負責完成的,具體研究結果被發(fā)表在日前出版的進化與發(fā)展雜志上。

"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 美國其他一些研究者認為這個發(fā)現(xiàn)非常有意思,但是要想在鯊魚神經(jīng)嵴細胞與電感受器之間建立直接聯(lián)系,還需要進行更多的研究。
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 美國其他一些研究者認為這個發(fā)現(xiàn)非常有意思,但是要想在鯊魚神經(jīng)嵴細胞與電感受器之間建立直接聯(lián)系,還需要進行更多的研究。這項研究是由美國佛羅里達大學的馬丁科恩和其
