Figure 2 Immunohistochemical expression of putative cancer stem cell markers by tumor buds in colorectal cancer. A: Cytokeratin 22 staining highlighting the presence of tumor buds in low power magnification (5 ×); B-I: 40 × magnification. Positive expression of ABCG5 (B), ALDH1 (C), and EpCAM (D) in tumor buds with scattered positive staining of stromal cells, absence of staining of CD133 in tumor buds with positive staining of stromal cells (E), positive expression of CD166 in tumor buds with occasional positivity of stromal cells (F), absence of CD24 (G), CD44s (H), and CD90 staining (I) in tumor buds with positive stromal cell expression.
