We examined ultrastructurally cerebral pericytes and astrocytes in 20 normotensive Wistar Kyoto rats and 60 asymptomatic stroke-prone spontaneously hypertensive rats, which were sequentially killed at 4-52 weeks of age. Another 30 SHRSP were killed soon after they showed symptoms of stroke. We found two kinds of pericytes around the capillaries; granular pericytes and filamentous pericytes

We set up a high-reproducible human-based in vitro BRB model using retinal pericytes, retinal astrocytes, and retinal endothelial cells in order to replicate the human in vivo environment with the same numerical ratio and layer order. Astrocytes that are stimulated with PCM produce factors promoting differentiation and myelination of OPCs. To elucidate how the differentiation of OPCs was induced in peri-infarct areas, we examined the intercellular interaction among pericytes, astrocytes, and OPCs, using cultured cells. Blood–retinal barrier (BRB) dysfunction represents one of the most significant changes occurring during diabetic retinopathy. We set up a high-reproducible human-based in vitro BRB model using retinal pericytes, retinal astrocytes, and retinal endothelial cells in order to replicate the human in vivo environment with the same numerical ratio and layer order.

Pericytes play critical roles in maturation and maintenance of vascular branching morphogenesis. In the central nervous system (CNS), pericytes are necessary for the formation and regulation of the blood-brain barrier (BBB) and pericyte deficiency accompanies CNS diseases including multiple sclerosis, diabetic Astrocytes wrap around endothelial cells using their endfeet. Pericytes, sandwiched in endothelial cells and astrocytes, signal to both cell types.

Pericytes are mural cells surrounding blood vessels, adjacent to endothelial cells. Pericytes play critical roles in maturation and maintenance of vascular branching morphogenesis. In the central nervous system (CNS), pericytes are necessary for the formation and regulation of the blood-brain barrier (BBB) and pericyte deficiency accompanies CNS diseases including multiple sclerosis, diabetic

These ECs express high levels of tight junction proteins that strongly minimize paracellular diffusion and cellular transmigration in homeostatic conditions [ 2 ]. Astrocytes and pericytes cooperatively maintain a capillary-like structure composed of endothelial cells on gel matrix. Itoh Y(1), Toriumi H, Yamada S, Hoshino H, Suzuki N.
