Real-time RT-PCR analysis of chick maxillary mesenchyme treated with Wnt3a-soaked beads. The chart shows real-time RT-PCR results for different genes from maxillary mesenchyme treated with BSA and Wnt3a. Each bar shows BSA treated sample on the left and experimental situation on the right. Msx1, Bmp4, Tbx22, Sox9, and Barx1 gene expression significantly increased following Wnt3a-soaked bead implantation in the maxillary prominences. Msx2 mRNA levels showed no significant difference from BSA treatment. Values are the mean ± S.E. in separate experiments using 9 embryos. *: P < 0.05, significantly different from the corresponding value for BSA treated group.
