Scientific notes - the Prethalamus is one active phase during the gastrulation and influences the encefalica region. The
neurale slab of the vertebrati
ones contains the distinguished dominions of the expression of the gene, which come prefigured in remote zones of the brain. It comes mappata a rappresentazione of the rostrale neurale slab that reveals presumablly the dominions inside secrets of the brain (posterior zone). These populations of the traced champions have cells very defined that they will be developed in some specific diencefaliche regions. In
order to verify if these sub-territories begin them already are engage to you in the precise identities, it has been begun to analyze the consequences derived from the possibility to transplant detailed lists cells in these populations. The transformation of these cells has been found that the
premonitory ones of the pre-
thalamus are already specialize to you and they are not replacable in is made been left over of the gastrula, poichè provokes to the loss of the pointers pre-thalamus. Moreover, once transplanted outside of the skull, these cells still pursue their pre-talamico program of differentiation. In order to conclude, the transplant of these premonitory ones, in rostrale the neurale epithelium and also, induces the changes in the identity of the cells in the
external brain which had to the external host. This cell-not-independent property has carried the theory that these premonitory
Pre-talamici laborers could carry out a role from instructor in the development of the diencefalica region.
