Title: How is the age of mouse embryo determined?
Post by: Dick on 02/11/2006 18:46:26

For example, the stage of a mouse E7.25 in an article. What does E7.25 mean and how is that stage measured?

Thanks,

Hi Dick.

Mice take 21 days to develop in utero following conception.

For ease we therefore talk about their age as an embryo, which is an E followed by their age. So a fifteen day old embryo would be E15.

Once they are born they are referred to as P, for post-partum. So a one day old mouse is P1 and a newly-born mouse would be P0.
