Term
|
Definition
| Specification of cell fates by the cell's own internal cytoplasmic components without reference to neighboring cells. |
|
|
Term
|
Definition
| Covert changes within a cell that restrict its developmental fate. |
|
|
Term
| Conditional specification |
|
Definition
| Position-dependent specification of cell fate by interaction between a cell and its neighbors. |
|
|
Term
|
Definition
| A (relatively) irreversible level of commitment to a particular developmental fate characterized by the ability of a cell or group of cells to differentiate to a particular fate even when placed into a different region of the embryo. |
|
|
Term
|
Definition
| A soluble molecule that is secreted from a source and whose concentration specifies one or more cell types along a concentration gradient. |
|
|
Term
| Morphogenetic determinants |
|
Definition
| Materials in the zygote cytoplasm that are segregated during cleavage and ultimately direct cell differentiation in later development. |
|
|
Term
|
Definition
| Pattern of embryogenesis associated with autonomous specification in which the embryo consists of a group of self-differentiating parts. |
|
|
Term
|
Definition
| A reversible level of commitment to a particular developmental fate characterized by the ability of a cell or group of cells to differentiate to a particular fate in a developmentally neutral environment. |
|
|
Term
|
Definition
| Specification of cell fates prior to cellularization of a multinucleate cleavage-stage egg. |
