The use of clonal analysis to obtain a fate map of the epiblast of the mouse embryo and to investigate cell distribution during gastrulation and early neurulation is described in a personal reminiscence. A revised fate map of the epiblast at 6.5 days gestation is provided, and the development of 3-dimensional, quantitative image analysis techniques outlined.
During animal ontogenesis, body axis patterning is finely regulated by complex interactions among several signaling pathways. Nitric oxide (NO) and retinoic acid (RA) are potent morphogens that play a pivotal role in vertebrate development. Their involvement axial of the head pharynx shows conserved features chordate phylum. Indeed, cephalochordate amphioxus, NO RA crucial for correct developme...
A comparison between static versus rotator culture systems and a variety of media (rat serum, new born calf serum, DMEM and Waymouth's) was made in an attempt to promote in vitro growth of mouse embryos from the beginning of neurulation (headfold stage) to the closure of the neural tube and formation of the limb buds (48 h). The results demonstrate that good development can be achieved for 48 h...
A molecular model for the morphogenesis of the central nervous system is built and solved by computer. The formalism rests on molecular-biological data gathered from insects and vertebrates during neural differentiation and neuronal fate specification. Two genetic, hierarchically organized switches are introduced, one associated with f1p4al tissue formation, and the other with neuronal specific...
Patents from papers both basic and applied Public funding for research depends on the idea that the resulting knowledge translates into socially valuable outcomes, such as medicines. Such linkages are easier to assert than to prove. Li et al. studied 27 years of grantlevel funding by the U.S. National Institutes of Health. About 10% of grants are directly cited by patents, suggesting some techn...
