Figure 6From: Differential expression of aldehyde dehydrogenase 1a1 (ALDH1) in normal ovary and serous ovarian tumorsExpression of ALDH1 was absent in regions with poorly differentiated tumor cell morphology while adjacent differentiated regions were highly stained. [A] Numerous cells expressed ALDH1 in differentiated tumor regions (D) with micro-papillary architecture. [B] Representative section with adjacent areas showing strikingly different ALDH1 expression in differentiated and poorly differentiated regions. [C] Reduced or absent ALDH1 expressing cells in poorly differentiated regions (P) with solid tumor cell nests. Sections were counterstained with hematoxylin. (Original magnifications: ×200, ×100 and ×200 respectively).Back to article page
