Cells (Embryology) Flashcards
Autocrine
a cell targeting itself
Signaling across gap junctions
targets a cell connected by gap junctions
Paracrine
A cell targets a nearby cell
Endocrine
A cell targets a distant cell through the bloodstream
Cell Differentiation
A cell forms from a general to a specific cell. Options get progressively restricted
Cell Specification
Refers to the fate of the cell. Not a permanent stage, and can be reversed based on cues/environment
Cell-cell communication and types
ability for cells to communicate. Autocrine, signalling across gap junctions, paracrine, endocrine
Cell Shape Changes
Shape links to functional role, critical in embryonic development
Main difference between epithelial to mesenchymal transition
The shape changes which changes the migratory potential
Which has stronger migratory potential: epithelial or mesenchymal?
Mesenchymal
Steps of Cell Migration
- Extension of Lamellipodium
- Formation of a new adhesion
- Translocation of the cell body
- De-adhesion and retraction at the trailing edge
Cell Movement
moving based on where it is needed. etc. tissue formation during embryonic development
Cell proliferation
cell grown and cell division
Cell death and types
When cells are no longer needed they die or commit suicide.
1. Apoptosis
2. Autophagy
3. Necrosis
4. Entosis
What kind of cell death leads to the formation of fingers and toes?
Apoptosis
