| | Thus, some somitic derivatives behave in a cell autonomous way concerning their positional information, while others are subject to cues from their environment. | | | However, if a similar experiment is conducted to investigate the nature of the muscles that develop, it is found that any somite will give rise to muscles appropriate for their new position. | | | The same procedure is "generic" and can be adapted easily for manipulation of newly-formed or older somites at stages 9-15, as well as for manipulations of the notochord, neural tube and other tissues at these stages. |
