| Hedgehog morphogens are associated with MPs shed from the plasma membrane of apoptotic stimulated T cells. |
| The Hedgehog proteins are secreted morphogens that provide positional information during the development of many multi-cellular animals. |
| The spread of their morphogens through epithelium promotes development. |
| The beautiful eyespots on butterfly wings are thought to rely on the principles described above, although involving more morphogens. |
| The researchers have thought that these so-called morphogens create chemical maps by simply diffusing through an embryo. |
| It's controlled by molecules called morphogens, which form concentration gradients along the head-to-tail axis, or other axes, of developing embryos. |
