cell differentiation
Let an agent handle cell differentiation by cell type, pathway, research use and regulation of stem cell applications.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent handle cell differentiation by cell type, pathway, research use and regulation of stem cell applications.
The process by which a less specialised cell becomes a more specialised cell type, such as stem cells becoming neurons, muscle or blood cells, controlled by gene expression and signals.
What it is for: Development, tissue repair and biomedical research.
It can be explain differentiation pathways; identify cell types and markers; understand stem cell research; check regulation of stem cell therapies.
Distinguishing features
Specialisation of cells
Driven by gene regulation
Usually stable but can be reprogrammed
Central to development
What it looks like
Seen under the microscope as changes in cell shape, markers and function.
How it is recognised
Marker proteins and gene expression
Lineage trees
