Y, C T oral vegetable plate is first Highest exposed to Nodal. From the data shown in Figure 8, it is naturally assumed that the precursor Shore, at the end, the group at the heart of the plate are aboral tea plant would. Specification process P2X Receptor of the five types of CMS based on the obtained results, the process of the five types of CMS as shown in Figure 9 will be drawn. An HPF 6 to occupy the offspring micromeres p The plant, and the 16th August veg2 blastomeres surrounded. At this stage, micromere progeny begin to express Delta. About 8 HPF occurs splitting ninth, and the descendants of the blastomeres veg2 are arranged in three rows. Precursor cells shore At the beginning, the derived group in the lower level

by Delta micromere descendants.
The HPF 10, a part of the rst The Preferences Shore situated at the heart of the group tee future oral, exposed to Nodal and are determined blastocoelar for Daunorubicin the cell line. About two-thirds of the precursor cells shore At the beginning, the group would be located in the heart tee aboral receive the signal and Delta are in the line of pigment cells indicated. These results are explained Ren Why the process of specification of pigment cells and cells blastocoelar erg Complementary or in competition with each other. Supposedly Notch disappears T pr Sumtiver SMC region, forming a hole notch, at p The vegetative. Therefore, the SMC precursor to lose Shore nodal cells exposed to their states, Civil Engineering in the Delta signal.
From this point, a lower veg2 progeny, ie, start precursors of pigment cells and the cells express blastocoelar delta. About 12 HPF begin micromere descendants to migrate into the blastocoel, and disappear from the plate plant. The Delta signal is still expressed in the lower tier of blastomeres veg2 derivatives, and identifies the precursors, the aboral end, a group in the middle tier on the heart-piece. Some, sp t would Preferences Shore of the group of nodal signal receiving up to 16 HPF. These cells are z Lomischen pouch cells and muscle precursor Given shore. Cell precursor Shore of needles, which are probably on your mind are the most aboral tip tea, m Not be legally possible exposure to Nodal. At least about 16 HPF begins, the plate invaginate system, accompanied by rearrangement of the cells that kr Ftig.
However, some would-cell precursor Shore leading contact pins to keep the pigment precursor Shore cells may need during the gastrulation. This is k Nnte why the cells are sensitive to the edge of spicules DCT, even in a sp Advanced stage. In the stage of hatching, the number of cells in the SMC line is in H. pulcherrimus 62 64, since the total number of precursor cells shore Of five types of CMS after the ninth cleavage business in 31 32 Protected. These figures are in good agreement with the number of cells that Gcm L. variegatus. As clearly demonstrated by Duboc et al, Nodal secreted from the area designated reach of the mouth indicated at least the c Ty of the oral plate plant. In the proposed model will be implemented gradually throughout the nodal plate of vegetables from the oral spread to the c Aboral tee. Although the results shown in Figure 8 support this hypothesis, it is currently not known whether this is really the case or not. This is an issue in the debate. complex, so that the observation of their behavior before the trailer ufung of cytopla
