Figure 3From: Validation of the effects of TGF-β1 on tumor recurrence and prognosis through tumor retrieval and cell mechanical propertiesAFM force-mappings of freshly prepared frozen tumor slices. (A) Image of the excised tumor. (B) Phase-contrast image of the central part of the tumor. The freshly prepared frozen tumor tissue slices were assessed by AFM. The compressive stiffness of (C) and the error-signal images and force-mapping of (D) Non-Rec tumor and (E) Rec tumors are presented. Scale bar = 10 μm. **, p < 0.01.Back to article page
