Effects of RAR-selective antagonist on mast cell growth under stimulation with SCF+ATRA or SCF+9-cis RA.
The effects of Ro 41-5253 (RARα antagonist) on the progeny generation from 1 × 104 10-week cultured mast cells in the presence of SCF plus ATRA or 9-cis RA were examined. Significantly different from no Ro 41-5253 (*P < .0005, **P < .0001).
