Fig. 7From: Preparation of UiO-66 loaded Letrozole nano-drug delivery system: enhanced anticancer and apoptosis activityCell migration test results. (A) control, (B) MCF-7 cell treated with free UiO-66, (C) MCF-7 cell treated with letrozole. (D) MCF-7 cells treated with UiO-66 bound to letrozole. The results showed that MCF-7 cells treated with UiO-66 bound to letrozole significantly inhibited cell migrationBack to article page
