For Konrad Hochedlinger of the Harvard Stem Cell Institue, it was a bad start to the week: Just after 6 a.m. last Monday, he and a bevy of others received an unsigned e-mail from a virtually untraceable address, [email protected], pointing out what it said «appears to be duplicated images and embryos used in a Nature manuscript published in 2009.»

The images are meant to show that the ES cells from cloned embryos look similar to those derived from IVF embryos, suggesting the cloned ES cells are the real thing.

The microscope's images can reveal the divisions and intricate rearrangements of individual cells as biological structures emerge in a developing embryo.

Each colored circle in the image shows one of the embryo's cells, and the corresponding tail indicates that cell's movement over a short time interval during early embryogenesis (at around 3 hours post-fertilization).

Among other things, the paper that Hertig and Rock published in 1954 contained some of the first micrograph images of a human embryo at the two - celled stage.

The group found that for species of snails that are dominantly sinistral, early embryo cell division is a mirror image of what happens in the dominantly dextral Lymnaea stagnalis.

By snapping 3D images of fluorescently labeled embryos, Kuroda's team found that in dextral snails, the spindles — tubular structures holding the chromosomes — are already spiraled and the cell boundaries seem twisted at an early stage of the third cleavage.

By implementing either superresolution structured illumination or by dithering the lattice to create a uniform light sheet, we imaged cells and small embryos in three dimensions, often at subsecond intervals, for hundreds to thousands of time points at the diffraction limit and beyond.

New images suggest that 570 - million - year - old, many - celled blobs from China are not animal embryos as once thought, but rather some kind of spore - releasing cyst.

Embryonic hemocytes lend themselves beautifully to live imaging studies since fluorescent probes can be expressed specifically in these cells using hemocyte specific promoters and their movements subsequently imaged within living embryos using confocal timelapse microscopy.

Analysis for embryos was done on images of seven different embryos (seven mutant and seven wild type embryos) inside gravid hermaphrodites (only one and two cell early embryonic stages were chosen for comparison).
