Cards

Term
Morphogenesis
Definition
Generation of form and structure within an organism during development.
Term
Differential adhesion hypothesis
Definition
Model of cell interactions which predicts that cells rearrange themselves into the most thermodynamically stable pattern, where the interfacial free energy is minimized.
Term
Differential cell affinity
Definition
Ability of different cells to selectively recognize other cells and substrates, adhering to some and migrating over others.
Term
Induction
Definition
Change in cellular behavior in a tissue in response to a signal produced by another tissue.
Term
Paracrine factor
Definition
A signal produced by an inducing cell or tissue that diffuses over a short distance and brings out changes in a responding cell or tissue.
Term
Juxtacrine factor
Definition
A molecule on the surface of a cell that induces a response in another cell.
Term
Competence
Definition
The ability of a tissue to respond to an inductive signal.
Term
Reciprocal induction
Definition
Situation in which one tissue receives and responds to a signal from another tissue in part by sending a signal back, creating a response in that tissue.
Term
Instructive interaction
Definition
Situation in which a specific signal from an inducing tissue is needed to bring about changes in gene expression in the responding cell.
Term
Permissive interaction
Definition
Situation in which a responding tissue only needs to a generally suitable environment to differentiate in some predetermined way.
Term
Endocrine factor
Definition
A molecule produced in one tissue that is secreted into the blood and delivered to a responding tissue in another part of the body; a hormone.
Term
Autocrine factor
Definition
A molecule produced by a cell that stimulates its own production in the same cell.
Term
Signal transduction pathway
Definition
A biochemical pathway that detects the presence of a signal molecule at the cell surface and brings about a response in the cell to the presence of the signal.
Term
Apoptosis
Definition
Genetically programmed cell death that is part of a normal developmental pathway.
