The brain and reproductive expression (BRE) gene is expressed in numerous adult tissues and especially in the nervous and reproductive systems. However, little is known about BRE expression in the developing embryo or about its role in embryonic development. In this study, we used in situ hybridization to reveal the spatiotemporal expression pattern for BRE in chick embryo during development. T...
During vertebrate embryonic development, a portion of the ectoderm (outer layer) is set aside to make neural tissue. These cells initially form a ‘neural plate’, which later folds into a tube that will form the spinal cord and brain (Fig. 1). As the folding occurs, precursor cells in the neural plate are transformed into different neuronal subsets. Surrounding non-neural tissues initially polar...
Maternal plasma fatty acid changes were measured in early pregnancy and an increase in maternal plasma DHA concentration is initiated in human pregnancy prior to neural tube closure which occurs at 28 days' gestation.
Embryonic chimera production was used to study the developmental processes of the mouse nervous system. The difficulty of performing in situ transplantation experiments of neural primordium of mouse embryo was overcome by isotopic and isochronic grafting of mouse neural tube fragments into chick embryo. Mouse neural tube cells differentiated perfectly in ovo and neural crest cells associated wi...
The development of the neural crest up to the stage where they leave the neural tube can be observed as a series of concatenated but independent events that involve dorsalization of the neural plate/neural tube, neural crest induction, segregation and stabilization, epithelial to mesenchymal transition and delamination. During all these processes, the nascent neural crest cells are subjected to...
