cell signaling
mechanism of action when inducer and responder interact
paracrine interaction
prots synthesized by one cell diffuse over SHORT dists to responders
juxtacrine interaction
do not involve diffusable proteins
1st way of juxtacrine interaction
prot ON CELL SURFACE interacts with a receptor on adjacent cell - notice no diffusion
2nd way of juxtacrine interaction
Ligands in EC MARTIX secreted by one cell interact with receptors on neighboring cells. Usually used for anchoring or migration track
3rd way of juxtacrine interaction
Gap Junctions - not paracrine which is EC diffusion - this is intracellular diffusion
GAP junctions - protein structure
made of connexin proteins
Rvw of chap 1:
Many inductive phenomena involve epithelial - mesenchymal interactions
can you picture that. Epitheleal is cell sheets while mesenchyme is fibroblastic cells dispersed in EC matrix
mature connective tissue also known as specialized connective tissue forms what structures?
