Back | Movies of CS12 embryos |
The movies below show volume renders of OPT models. No staining has been used on any of the specimens and the images were captured using autofluorescence with a FITC filter.

Back | Painted Anatomical Regions |
The movies below show anatomical domains defined in the N288 and N476 models. The domains have been manually defined in the OPT models using specialised software and then visualised using commercial rendering packages.
The various domains are: neural tube - orange; heart - red; liver - dark green; optic vesicle - dark blue; otic vesicle - yellow; dermatomes - cyan.
