Quantitative study of mast cells in experimentally induced benign prostatic hyperplasia

Area of Science:

• Urology
• Cell Biology
• Histology

Background:

• Mast cells mediate biological responses via growth factor and cytokine release.
• Their role in benign prostatic hyperplasia (BPH) pathogenesis is not fully understood.
• This study investigates mast cell changes in experimentally induced BPH.

Purpose of the Study:

• To quantify and map mast cell distribution in rat prostates with experimentally induced BPH.
• To explore the morphological characteristics of mast cells in this model.
• To determine the potential involvement of mast cells in BPH development.

Main Methods:

• Adult Wistar rats received transdermal citral for one month to induce BPH.
• Prostate tissues were analyzed for morphological characteristics.
• Mast cell concentration was assessed in proximal and distal zones using hematoxylin-eosin and Giemsa staining.

Main Results:

• Transdermal citral successfully induced mild benign prostatic hyperplasia.
• A significant increase in mast cell numbers was observed in both proximal and distal prostate zones.
• Mast cells in the BPH model were larger, contained more granules, and showed degranulation.

Conclusions:

• Transdermal citral significantly elevates mast cell counts in the rat ventral prostate stroma.
• Increased mast cell size, granularity, and degranulation suggest active involvement.
• These findings indicate a potential role for mast cells in the pathogenesis of benign prostatic hyperplasia.
