Fig. 4. Inhibition of Smad2 signaling enhances neural induction by low doses of BMP inhibitors in Xenopus animal caps. Blocking Smad2 signaling with tActRIB (1 ng) led to more efficient neural induction by low doses of BMP inhibitors tBMPRIA (0.1 ng), Smad6 (10 pg) or VP16-Msx1 (25 pg) in animal caps.
