Abstract

Background: The intricate microvascular structures of the brain play a critical role in maintaining cerebral homeostasis and ensuring adequate delivery of oxygen and nutrients to neuronal tissues. Understanding their architecture can provide insights into various neurological disorders and conditions. Objective: To elucidate the morphology and distribution of microvascular structures in various regions of the brain using cross-sectional histological analysis. Methods: Post-mortem human brain tissues from ten donors were acquired, with appropriate ethical considerations. Tissues were sectioned and stained using standard hematoxylin and eosin, as well as immunohistochemical markers specific to endothelial cells. Regions of interest, including the cortex, basal ganglia, and hippocampus, were examined under high-resolution microscopy. Results: Preliminary observations revealed a dense network of capillaries uniformly distributed in the cortical regions. The basal ganglia demonstrated larger vessels with increased branching, while the hippocampus exhibited a unique vascular pattern consistent with its layered structure. Immunohistochemical staining confirmed the presence of intact endothelial cells and tight junctions, suggesting well-preserved microvascular integrity. Conclusion: This study underscores the diverse microvascular architecture across different brain regions. Understanding these differences may aid in predicting region-specific susceptibilities in various cerebrovascular disorders and facilitate targeted therapeutic interventions.
