Pericytes in retina

WebJan 1, 2024 · Pericytes (PCs) are specialized cells located abluminal of endothelial cells (ECs) on capillaries, embedded within the same basement membrane. They are essential regulators of vascular development, remodeling, and blood-retina-barrier (BRB) tightness and are therefore important components to maintain tissue homeostasis. WebOct 14, 2024 · Pericytes in the brain, and possibly also in the retina, have many similarities to mesenchymal stem cells (MSC) (Lange et al. 2013 ). They possess a pluripotent differentiation potential, enabling them to generate a variety of cell types.
