Chan WY & Tam PP. Without understanding normal development the molecular biologists don't stand a hope of understanding what their gene knock out has done. 2. Expression levels of GR in the hippocampus and UCN3 in the perifornical area are low at birth but increase significantly during the SHRP, both reach maximum expression level at pnd 12. second phase - mice developed past the SHRP exhibit enhanced corticosterone basal levels and a response of ACTH and corticosterone to mild novelty stress. Olfactory stimuli are known to induce true pseudopregnancy (as shown by deciduoma formation) in crowded all-female groups (van der Lee and Boot, 1955 , 1956 ).

Because of this exceptional fecundity, mixing male and female mice into the same cage can be dangerous--unless, of course, you want babies. Taher L, Collette NM, Murugesh D, Maxwell E, Ovcharenko I & Loots GG. Formation of the distal portion of the mouse urethra receives substantial contribution from the preputial swellings that form the preputial-urethral groove and subsequently the preputial-urethral canal, the later of which is subdivided by a fusion event to form the distal portion of the mouse penile urethra. Retrieved from https://embryology.med.unsw.edu.au/embryology/index.php/Mouse_Development. Light blue - indicate mesenchymal condensations.

(2011). A pregnancy test can easily confirm if you are pregnant. If your mouse really trusts you (if she's the type who crawls onto you when you put your hand in, and is otherwise happy to see you) then you can hold the babies as early as 3 or 4 days.
