CVM cells (red) follow along a track made of TVM (green) cells. The TVM cells emit a signal, letting CVM cells know that they are going the right direction. The CVM cells are approaching a bend in the embryo where they will encounter high BMP (blue) signals, which will indicate that CVM need to replicate themselves and multiply. BMP signaling also triggers the expression of a "poisonous" gene, called hid, and unless the proliferating cells stick closely to the TVM track, hid will kill them. In this way, the developing embryo performs quality control, ensuring that any wayward cells are eliminated.
