or the vehicle 2-hydropropyl-β-cyclodextrin (HβCD)
(Sigma-Aldrich) alone as a control, (essentially as described by van den Brink
(van den Brink et al. 2001 (link))). Mice
were injected (250 μl max volume) intraperitoneally (IP) 1 day before
ligation, then every other day after ligation at a dose of 10 mg/kg cyclopamine
(Sigma-Aldrich) dissolved in a solution of 45% (w/v) HβCD. There
was no effect of cyclopamine treatment on mouse body weight, compared to the
HβCD vehicle control group (data not shown).
