The primary stimulator of pericyte proliferation, however, is PDGF. Figure 3 depicts the ischemia-driven upregulation of VEGF, PDGF, FGF and Ang-2 and their target cells (stromal cells ...

Behaviour is the set of responses that an organism makes to stimuli. Stimuli are environmental changes that an organism can detect. A behavioural adaptation is a behaviour that helps an organism ...

They detect a change in the environment (stimulus) and stimulate electrical impulses in response. Sense organs contain groups of receptors that respond to specific stimuli.

These signaling pathways involve transferring the information generated by external stimuli at the cell surface to intracellular effector systems such as nuclei. The informational processing of ...

Expert Rev Ophthalmol. 2013;8(6):527-537. Protein kinase C-mediated contraction of RPE cells is stopped by an anti-PDGF antibody. Unfortunately, blocking PDGF is ineffective at suppressing PVR in ...
