Term-pregnant
C57BL/6JRj mice were purchased (Janvier Labs, Le Genest-Saint-Isle, France). After arrival, the mice were housed in type II long filter-top cages (
SealSafe Plus, polyphenyl sulfone, 365 mm L × 207 mm W × 140 mm H, Greenline; Tecniplast, Buguggiate, Italy). The mice were kept in a 12:12 h light/dark cycle (lights 06:00–18:00) in a temperature- and humidity-controlled animal room (22 ± 2 °C, 55 ± 5%). Food (
ssniff M-Z Extrudat, ssniff, Soest, Germany) and water were supplied ad libitum.
The pup was sacrificed with sodium pentobarbital (i.p. 0.1 mL/10 g BW,
Narcoren® (16 g pentobarbital sodium 16.0 g, benzyl alcohol 3.0 g; Boehringer Ingelheim, Ingelheim, Germany)) at P5 for micro-computed tomography.
