|
Determination |
Commitment of a cell to a function in the future. |
|
|
Morphogens |
Specific molecules secreted to induce determination. |
|
|
Differentiation |
Change in structure, function, biochemistry of cell after pathway has been determined. |
|
|
Totipotent |
Greatest level of potency. Ultimately can turn into any cell type in fetus or placental structures. Includes embryonic stem cells. |
|
|
Pluripotent |
Can differentiate into any cell type except for those found in placental structures. |
|
|
Multipotent |
Can differentiate into multiple types of cells within a particular group. |
|
|
Responder |
Cell that is induced |
|
|
Competent |
State a cell must be in order to respond to an inducing signal. |
|
|
Autocrine Signals |
Act on the same cell that secreted the signal. |
|
|
Paracrine Signals |
Act on cells in the local area. |
|
|
Juxtacrine Signals |
Do not usually involve diffusion, but feature a cell directly stimulating receptors of adjacent cell. |
|
|
Endocrine Signals |
Involve secreted hormones that travel through the bloodstream to a target tissue. |
|
|
Growth Factors |
Most common kind of inducers; peptides that promote differentiation and mitosis in certain tissues. |
|
|
Reciprocal Development |
Where induction is not a one-way pathway, and two growing tissues can influence each other simultaneously. |
