Effects of ATRA on mast cell growth by CD34+ cord blood cells.
CD34+ cord blood cells (1 × 104) were cultured with 100 ng/mL of SCF and/or ATRA at 10−9mol/L to 10−7 mol/L. The viable cells were enumerated until 4 weeks. The results shown are from 1 representative experiment of 3. Similar results were obtained in the other 2 experiments. Significantly different from SCF alone (*P < .0001).
