The notochord is an elastic, ... 180 degrees opposite of the normal notochord location, one can induce the formation of motor neurons in the dorsal tube.
Homeobox protein notochord (NOTO) is a transcription factor [1] encoded by the gene notochord homeobox (NOTO) located on the short arm of chromosome 2 (2p13.2) in humans (Homo sapiens). [2] An ortholog of NOTO is found in the house mouse ( Mus musculus ), among other species, as the gene notochord homeobox ( Noto ) located on chromosome 6 ...
The internally located neural tube; The externally located epidermis; The neural crest cells, which develop in the region between the neural tube and epidermis but then migrate to new locations; Primary neurulation begins after the neural plate forms. The edges of the neural plate start to thicken and lift upward, forming the neural folds.
The notochord plays an integral role in the development of the neural tube. Prior to neurulation, during the migration of epiblastic endoderm cells towards the hypoblastic endoderm, the notochordal process opens into an arch termed the notochordal plate and attaches overlying neuroepithelium of the neural plate. The notochordal plate then ...
The dorsal nerve cord is located dorsal to the notochord and thus also to the gut tube (hence the name). It is formed from clustered neuronal differentiation at the axial region of the ectoderm , known as the neural plate .
Cells in this area, known as medial hinge point cells because of their involvement with this structure, are stabilized and connected to the notochord. They are derived from the area of the neural plate anterior to primitive knot. The notochord will begin the shape changes in MHP cells. These cells will decrease in height and become wedge-shaped.
The notochord extends from the base of the head to the tail; with it extend thick bands of paraxial mesoderm. [1] As the primitive streak continues to regress, somites form from the paraxial mesoderm by "budding off" rostrally as somitomeres, or whorls of paraxial mesoderm cells, compact and separate into discrete bodies. The periodic nature of ...
