Prof. Dr. Haider Abdulrasool Jaafar and Asst. Prof. Dr. Huda Rasheed Kareem, faculty members in the Department of Human Anatomy – College of Medicine – Al-Nahrain University, participated as members of the Ph.D. thesis defense committee for the doctoral student Huda Hussein Eid at the College of Medicine – Tikrit University, on Monday, May 12, 2025. The thesis was entitled: “Histological and Histochemical Evaluation of Age-Related Changes in Breast Architecture in Iraqi Women (A Light and Electron Microscopy Study)” The study focused on analyzing the structural changes in breast gland tissue among Iraqi women using light microscopy, transmission electron microscopy (TEM), and immunohistochemical staining for E-cadherin, a key biomarker involved in epithelial cell adhesion. The research included 60 tissue samples categorized into three age groups. The results revealed significant differences in lobule count, epithelial thickness, and connective tissue characteristics across the groups. Additionally, the study demonstrated signs of atrophy and varying degrees of glandular activity depending on age. The findings highlighted that E-cadherin expression was more prominent in active epithelial cells, underscoring its structural role in maintaining tissue cohesion. The defense committee praised the scientific and methodological quality of the thesis, emphasizing the importance of its findings in providing a reference histological database. This can aid in distinguishing between physiological and pathological changes in breast tissue, thereby opening new avenues for future clinical studies.
