Abstract

Introduction:

This study was carried out to investigate the expression of connective tissue (Collagens I and III), glia and neuronal markers in the testis of the African giant rat using histology and immunohistochemistry techniques.

Materials and Methods:

Eight (8) apparently healthy wild male African giant rats were used for this experiment, divided into 2 groups (juvenile and adult) of 4 animals each. The testes were harvested following intracardial perfusion of the rats and histology was performed using Haematoxylin-Eosin stain and Mallory-Heideinhain rapid one- step staining for connective tissue. Immunohistochemical identification was achieved using the following antibodies: anti-collagen type I, anti-collagen type III, anti-glial fibrillary acidic protein and anti-p75 nerve growth factor for the expression of collagen type I, collagen type III, astrocyte-like cell and neuronal cells respectively. Photomicrography was achieved using Axioskop® microscope and quantitative data were analyzed using student t-test.

Results:

The cyto-architecture of the testis was typical in the African giant rat. The connective tissue expressed in the juvenile and adult group, signaling of glial-like cells were seen in the perivascular region across the experimental groups. Immuno-localization of neuronal cells were seen in the interstitial spaces across all the groups, but with more expressions in the juvenile. Conclusion: This work has provided a clear description of the expression of connective tissue, neuronal and glial cells in the testis of the African giant rat and their possible relationships across juvenile and adult groups.
