Expression Pattern :

Pattern  A hybridization signal was first detected in the nucleus of the E cell at the 8-cell stage, indicating the onset of zygotic expression of tbx-9 in this cell. Expression in the E cell was retained in its daughter cells Ea and Ep until the 24-cell stage. It then became undetectable. At this stage, signals were detected in five more cells. After this stage, signals were observed in a subset of cells at each stage up to the approximately 400-cell stage and became undetectable just before the onset of morphogenesis. The most intensive hybridization signals were found in four cells at the approximately 200-cell stage. These cells were arranged as two pairs of two cells near the center of embryos, a location usually occupied by MS descendant cells. For exact orientation, embryos were subjected to double staining by fluorescence in situ hybridization for the tbx-9 mRNA along with marker mRNAs. Two of the tbx-9 expressing cells were identified as the Ca and Cp cells. Double staining by fluorescence in situ hybridization for tbx-9 and elt-1 revealed the remaining three tbx-9 expressing cells were AB descendant cells destined for hypodermal cells.
