In the current study, messenger RNA will be obtained from cardiac tissue of embryos that have been treated with 100nm of ATRA in the neurula stage of development. |
The early neurula is finished with formation of the expressed nervous plate and a cavity of a primary gut. |
While the notochord and somites are developing, the neural plate ectoderm above them begins to develop into the neural tube and the embryo is then called a neurula. |
