Two collagen films prepared for the in vitro study. (A) Normal collagen film, which mimics the ECM of normal blood vessels. Typical SEM image (B) and AFM image (C) of the collagen film. (D) Denatured collagen film, which mimics the ECM of abnormal blood vessels. The structure of the denatured collagen film was intentionally broken using collagenase to simulate the abnormal ECM. Typical SEM image (E) and AFM image (F) of the denatured collagen film.
