Supplemental Figure 3B from Calcium-Induced Differentiation of Human Colon Adenomas in Colonoid Culture: Calcium Alone versus Calcium with Additional Trace Elements

Higher magnification images of the immunostained colonoid sections. Immunohistology (as shown in Figures 3 and 4). At the end of the 30-day incubation period, colonoids were examined under light-microscopy after immunostaining for CK20, E-cadherin, occluding, cleaved caspase-3 and NF-2. Bars=50 μm.
