Research on the Human Leptomeningeal Pericytes is essential to the study of pathological conditions such as hypertension, diabetic retinopathy, atherosclerosis, multiple sclerosis, Alzheimer's disease, and tumor angiogenesis. The meninges are three layers of protective membranes that surround the brain and spinal cord. From outermost to innermost, they are the dura mater, arachnoid mater, and pia mater. The meninges act as a barrier between the central nervous system and the surrounding bones, providing structural support, cushioning against external impacts, maintaining cerebrospinal fluid circulation, and contributing to the formation of the blood-brain barrier. The Human Leptomeningeal Pericytes are to be used with Human Leptomeningeal Pericyte Medium (Cat. No. ACM0093). This product is intended for laboratory in vitro use only. It is not intended for diagnostic, therapeutic, or clinical applications.
