Researchers stained the cells of a mouse embryo that had its tissue cleared so they could watch its nervous system and blood vessels develop in tandem. This 13.5-day-old embryo, viewed under a ...

William Lensch work in Dr. George Daley's laboratory in the Division ... cell mass (A), membrane-like cells (B), and placental cells (C). Only the embryonic stem cells are able to continue growing ...

As she looked more closely across all stages of embryo ... cells still carry the germline genomes from the gametes that produced the first cell. As early as the two or four-cell stage, the DNA begins ...

First, short DNA sequence tags called unique molecular identifiers (UMIs) are added to cells. They attach to DNA and RNA molecules and begin making copies of themselves. This starts a chemical ...

An international research team has provided a detailed insight into how the spatial organization of genetic material is established in the cell nucleus of early embryos within the first hours after ...

Under a microscope, scientists then aimed tiny beams of light onto specific regions of these cells. As they did this, the light-sensitive GEF activated Rho proteins exactly where the light shone.

They have different cell shapes and patterns of division. Left, fission yeast; right, budding yeast; visualized with the nuclear DNA stain DAPI (4',6-diamidino-2-phenylindole) to highlight the ...

To prepare the 46 chromosomes of a human cell for transport to the daughter cells during cell division ... this process in high resolution under the microscope using a new chromatin tracing ...

An international research team led by Helmholtz Munich has, for the first time, provided a detailed insight into how the spatial organization of genetic material is established in the cell nucleus of ...

Scientists were able to identify chromosomes under the microscope as early as the 19th ... precise distribution of nuclear material during cell division. His work provided an invaluable ...
