• in the absence of tamoxifen no thymus abnormalities are detected
• treatment with tamoxifen at 12 and 24 months of age reverses thymus involution as measured by increase in thymus size and thymocyte numbers, and the presence of clearly defined cortical and medullary regions
• increase in the proliferation of thymic epithelial cells in mice treated at 12 and 24 months of age with tamoxifen compared to age matched controls
