Researchers have successfully attached imaging probes to glycans -- the sugar molecules that are abundant on the surfaces of living cells -- in the embryos of zebrafish less than seven hours after ...

Certain aspects of human reproductive biology are well understood; we know that when a sperm enters an egg, the genetic material from each cell merges to form a zygote, which develops into a human ...

The journey of the egg and the embryo through the fallopian tube or oviduct toward the uterus is not well understood, mainly because it is inaccessible for direct imaging. Looking to shed new light on ...

Live imaging of embryos at different stages. Chromosomes are labeled in magenta. 4-cell sister blastomeres are shown, along with 3D-reconstructed images of 2-to-4-cell and 4-to-8-cell divisions.

Scientists have shed light on an important stage of early embryonic development that has never been fully mapped out in humans before. Due to more readily available samples, studies so far have ...

Cytochrome oxidase activity via cytochrome c, as demonstrated by the diaminobenzidine procedure, has been employed in this electron microscope cytochemical study to determine the respiratory potency, ...

A new discovery by researchers at the RIKEN Center for Biosystems Dynamics (BDR) in Japan upends decades of assumptions regarding DNA replication. Led by Ichiro Hiratani and colleagues, the ...
