ALDH1A1 and breast carcinoma: In contrast, 468ALDH1A3low and 159ALDH1A3low cells were observed to be significantly more adherent and more migratory (Figure 3B,C) than respective control cells (p < 0.05), suggesting that adhesion and migration of human breast cancer cells is differentially influenced by ALDH1A1 versus ALDH1A3.
