Fig. 2. BMP-dependent NC delamination from explanted neural primordia is inhibited
by the G1/S transition blocker mimosine. (A) Control, and (B) 600 µm
mimosine, (C) 100 ng/ml BMP4 and (D) mimosine+BMP4 treatment. Left panels are
phase-contrast images and right panels depict BrdU immunoreactivity. (E) Data
quantification. NC delamination is significantly stimulated by BMP4
(P<0.005) and inhibited by mimosine (P<0.005) relative
to controls. Mimosine prevented BMP4-induced NC delamination
(P<0.002 relative to BMP4 alone) and BrdU incorporation. Scale
bar: 75 µm.
