Theiler Stage Reference

A reference table of the approximate correlation between Theiler Stages and dpc.

The definitions of Theiler stages used in GUDMAP, and their relationship to days post-coitum (dpc), are those that appear on the EMAP website.

Each Theiler stage is identified with one ‘average’ age, and a range of variation of real ages, centering on this average, that can be seen when real developing embryos are studied.
