Introduction
Rats (taxon - rattus) are readily available as inbred, outbred and mutant strains. They have been generally beaten as a model by their rodent mice brethren, as the molecular tools that became available (stem cells, knockout genes, etc).
Rat embryos do have the advantage of being much larger than mouse embryos and easy to breed. Another advantage of rats is in vision development studies, as that retinal development continues postnatally (most vertebrate neurological systems are difficult to access during periods of development). Rat development is also generally 1 day behind that of mouse. (The table below gives details relating to the staging of rat development). Below this are a list of internet resources relating to the rat.

Species Stages Comparison
The table below gives an approximate comparison of human, mouse and rat embryos based upon Carnegie staging.
Carnegie | Stage | |||||||||||||||||||||||
Human | Days | 1 | 2-3 | 4-5 | 5-6 | 7-12 | 13-15 | 15-17 | 17-19 | 20 | 22 | 24 | 28 | 30 | 33 | 36 | 40 | 42 | 44 | 48 | 52 | 54 | 55 | 58 |
Mouse | Days | 1 | 2 | 3 | E4.5 | E5.0 | E6.0 | E7.0 | E8.0 | E9.0 | E9.5 | E10 | E10.5 | E11 | E11.5 | E12 | E12.5 | E13 | E13.5 | E14 | E14.5 | E15 | E15.5 | E16 |
Rat | Days | 1 | 3.5 | 4-5 | 5 | 6 | 7.5 | 8.5 | 9 | 10.5 | 11 | 11.5 | 12 | 12.5 | 13 | 13.5 | 14 | 14.5 | 15 | 15.5 | 16 | 16.5 | 17 | 17.5 |
