Early expression of the tbx22 gene in zebrafish influences positioning of pharyngeal arch cartilages
... While examining the signals downstream of bapxI, we did uncover a decrease in gdf5 expression in the tbx22-2 knockdown embryos. This decrease in gdf5 could be the result of a decrease in bapxI expression, but this is not ...
