Abstract: Understanding the glomerular vascular pole's physiology and biodiversity is crucial for comprehending crescent development and peripolar regeneration. The current study looked into the primary histological differences between domestic and wild animals as well as the histological characteristics of the specialized cells in renal corpuscles. Two groups of six rats each were created from two strains of rats used in the experimental study. The wistar albino rats (Rattus norvegicus) were created at the animal house/pharmacology collage at Kerbala University, while the brown rats (Rattus norvegicus) were captured from agricultural areas and orchards in the Karbala governorate. For a general histological investigation, use the hematoxylin and eosin stains. Collagen fibers are examined with Masson trichrome and the Gomori trichrome stain. The peripolar cell lies adjacent to the visceral and parietal glomerular layers near the Bowman’s capsule. Their outside surface is open to the urine space in a peripolar posture. In both lab and wild rats, the peripolar cells that were contain expanded with processes, type of these cells present within them were dendritic peripolar cells. These were one specific type of dendritic cells observed in rats. In lab rats, their cell bodies were pyramidal, but in wild rats, the shape of peripolar cells they were fusiform shape and spherical shapes. They often had greater microvilli than parietal epithelial cells. Most cells had a few non-branching extensions and wrapped tightly around the vascular pole. The gap that exists between afferent and efferent arteries contains a number of peripolar cells with extensions extending in opposite ways. These cells illuminate red whenever examined with Masson trichrome. The form of dendritic peripolar cells varied, indicating functional specialization. They may be essential for crescent formation and peripolar regeneration due to their localization and expansions surrounding the vascular pole.
