Patterning of the Vertebrate Head in Time and Space by BMP Signaling.
How head patterning is regulated in vertebrates is yet to be understood. In this study, we show that frog embryos injected with Noggin at different blastula and gastrula stages had their head development sequentially arrested at different positions. When timed BMP inhibition was applied to BMP-overexpressing embryos, the expression of five genes: xcg-1 (a marker of the cement gland, which is the front-most structure in the frog embryo), six3 (a forebrain marker), otx2 (a forebrain and mid-brain marker), gbx2 (an anterior hindbrain marker), and hoxd1 (a posterior hindbrain marker) were sequentially fixed. These results suggest that the vertebrate head is patterned from anterior to posterior in a progressive fashion and may involve timed actions of the BMP signaling.
期刊介绍：
The Journal of Developmental Biology (ISSN 2221-3759) is an international, peer-reviewed, quick-refereeing, open access journal, which publishes reviews, research papers and communications on the development of multicellular organisms at the molecule, cell, tissue, organ and whole organism levels. Our aim is to encourage researchers to effortlessly publish their new findings or concepts rapidly in an open access medium, overseen by their peers. There is no restriction on the length of the papers; the full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. Journal of Developmental Biology focuses on: -Development mechanisms and genetics -Cell differentiation -Embryonal development -Tissue/organism growth -Metamorphosis and regeneration of the organisms. It involves many biological fields, such as Molecular biology, Genetics, Physiology, Cell biology, Anatomy, Embryology, Cancer research, Neurobiology, Immunology, Ecology, Evolutionary biology.
