| The Hedgehog proteins are secreted morphogens that provide positional information during the development of many multi-cellular animals. |
| He suggested that biological forms mirror patterns in the concentrations of hypothetical chemicals called morphogens. |
| The beautiful eyespots on butterfly wings are thought to rely on the principles described above, although involving more morphogens. |
| The spread of their morphogens through epithelium promotes development. |
| Hedgehog morphogens are associated with MPs shed from the plasma membrane of apoptotic stimulated T cells. |
| Plant growth and development is orchestrated by several classes of morphogens. |
