Apoptosis in Embryonic Development

Apoptosis, or programmed cell death, is a mechanism in embryonic development that occurs naturally in organisms. Apoptosis is a different process from cell necrosis, which is uncontrolled cell death usually after infection or specific trauma. As cells rapidly proliferate during development, some of them undergo apoptosis [3], which is necessary for many stages in development, including neural d...

Patterns of embryonic development

The embryology of reptiles is an important component of two emerging research areas. One area is the result of the marriage of molecular and developmental biology. Molecular biology has provided the tools to demonstrate the genetic commonality of developmental patterns, and thus provides novel insights into the origin and maintenance of structural diversity across the animal kingdom (Raff, 1996...

Shaping embryonic development.

Embryonic Development and Induction

95 gestion that viruses, from the type which appears to be of molecular proportions to those which are essentially microorganisms in the bacterial sense-have one (at least) distinguishing characteristic in common,-parasitism. From this he deduces: "We would suppose that the larger viruses were organisms which had lost the power to synthesise some factor or factors essential for their growth and...

Reconstructing embryonic development.

Novel approaches to bio-imaging and automated computational image processing allow the design of truly quantitative studies in developmental biology. Cell behavior, cell fate decisions, cell interactions during tissue morphogenesis, and gene expression dynamics can be analyzed in vivo for entire complex organisms and throughout embryonic development. We review state-of-the-art technology for li...
