Which tissues below are NOT typically derived from the cells on the dorsal surface of a mammalian embryo after gastrulation once some of these cells begin expressing N-cadherins and stop expressing E-cadherins?

B)brain
C)spinal cord
D)neural tube

Question

Quizplus · Accepted Answer

The cells on the dorsal surface of a mammalian embryo after gastrulation that express N-cadherins and stop expressing E-cadherins typically give rise to neural tissues, such as the brain, spinal cord, and neural tube. The skin is derived from the ectoderm, which is located on the surface of the embryo and does not express N-cadherins or stop expressing E-cadherins.
