We report studies of preimplantation human embryo development that correlate time-lapse image analysis and gene expression profiling. By examining a large set of zygotes from in vitro ...

This is precisely the time when the embryo undergoes profound changes in shape and develops precursors of various organs -- a highly complex process that leaves many questions unanswered.

A small tissue fold in fly embryos, once thought purposeless, plays a vital role in stabilizing tissues. Researchers show that it absorbs stress during early development, and its position and timing ...

Research led by the University of Plymouth has shown that a new deep learning AI model can identify what happens and when during embryonic development, from video.

In contrast to the development of other animals whose embryonic cells rely on chemical signals for orientation, in P. hawaiensis the grid patterning is a mechanical event that spans two regions — one ...

Roe deer are among the few mammals whose embryos go into a particularly long period of dormancy. Using modern molecular methods, ETH Zurich researchers have shown for the first time exactly what ...

Scientists recorded in 3D and in real time the exact moment a human embryo implanted itself in an artificial uterus, opening ...

Researchers have now found, however, that during a crucial stage of development, the regulation of alternative splicing goes wild. Reporting in Science, investigators studied the very early ...

With today's advanced microscopes, scientists can capture videos of entire embryos developing in real time. But there's a catch: turning those breathtaking images into clean, accurate trajectories of ...

1. To test the hypothesis that rapid embryogenesis is an adaptation to cold climate, embryonic development time was measured in three oviparous species of Sceloporus that occur at different altitudes: ...

Molecular gradients established as a key driving force for cellular organization during the formation of early structures during embryonic development.
