Purpose:

In furthering the understanding of the process of spermatogenesis in the greater cane rat, this study describes the ultrastructural spermiogenic transformation and acrosomal formation in the testes of this hystricomorphic rodent that is currently undergoing domestication in parts of West Africa.

Materials and Methods:

Testicular samples were obtained from ten sexually mature cane rats that were perfused-fixed using Karnovsky's fixative (phosphate buffered 2% paraformaldehyde – 2.5% glutaraldehyde fixative at pH 7.4). The samples were processed for ultrastructural analysis and examined under the transmission electron microscope.

Results:

The testes of the cane rat showed uniqueness in its cellular associations and …

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 …
