Following microscopy and image analysis, embryos were genotyped for the gba1 mutation (as described earlier).
Discontinuous measurements of cellular velocities have been made in zebrafish embryos using video microscopy, and in transgenic mouse embryos expressing GFP-labeled erythrocytes using perpendicular linescans [ 15, 19].
Using light and scanning microscopy, gynoecium, ovule and embryo-sac development are described in two (of 4) species of Lophophytum.
After thawing (water bath, 0 or 25 °C), embryos were evaluated by stereoscopic microscopy and the percentage of embryos with intact morphology was registered.
This article illustrates early human development, demonstrated by magnetic resonance (MR) microscopy and computer graphics on human embryo specimens, and advanced 3-dimensional (3D) sonography in clinical obstetrics.
The phenotype of embryos among litters from Axd/+ intercrosses was examined by scanning electron microscopy (70 embryos) and light microscopy (>300 embryos), at developmental stages during and after the stage of spinal neural tube closure (E9.5 10.5 and later).
Two days after injection, a GFP signal was detected in 4-cell embryos by fluorescence microscopy and higher GFP expression was observed in morulae and blastocysts on day 3 and day 4, whereas no GFP signal was observed in control embryos injected only with the Nanog::EGFP construct and dCas9VP48 plasmid.
Suspecting enzymes were creating this escape hatch (when most frog embryos are ready to hatch, they secrete enzymes from their heads that slowly degrade the egg membrane), the team scoured red-eyed tree frog embryo heads using electron microscopy and found clusters of glands on the snouts that were packed prior to hatching but were empty in newly hatched tadpoles.
For electron microscopy of mouse embryos, E8.5 embryos were prepared and treated the same as above.
