The evolution of worms, insects, vertebrates and other “bilateral” animals from less complex creatures like jellyfish and sea anemones with “radial” symmetry may have been facilitated by the emergence of a completely new "operating system" for controlling genetic instructions in the cell.
About seven days after conception, something remarkable occurs in the clump of cells that will eventually become a new human being.
An international team of scientists using a new X-ray method recorded the internal structure and cell movement inside a living frog embryo in greater detail than ever before.
Classical X-ray radiographs provide information about internal, absorptive structures of organisms such as bones.
An embryo is an amazing thing. From just one initial cell, an entire living, breathing body emerges, full of working cells and organs. It comes as no surprise that embryonic development is a very carefully orchestrated process—everything has to fall into the right place at the right time.
Scientists have found that the gut endoderm has a significant role in propagating the information that determines whether organs develop in the stereotypical left-right pattern.
For all animals, development begins with the embryo.
Avian embryos could join the list of model organisms used to study a specific type of cell migration called epiboly, thanks to the results of a study published this month in the journal Developmental Dynamics.
Researchers with the U.S. Department of Energyâ€™s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC), Berkeley, have successfully attached imaging probes to glycans â€“ the sugar molecules that are abundant on the surfaces of living cells â€“ in the embryos of zebrafish less than seven hours after fertilization.
Clusters of mouse embryonic stem cells called embryoid bodies more closely approximate true embryos in organization and structure than previously thought, according to researchers at the Stanford University School of Medicine.
