FIG. 6.

ECM scaffold promotes cell–matrix and cell–cell interactions. (A, A1) Representative SEM images showing cell–matrix interactions. White arrows in A indicate cellular processes embedded in the scaffold. (A1) High-magnification image of the boxed area in A. (B, B1) Representative images showing cell–cell interactions on the ECM scaffold. Numbers 1 and 2 in B indicate two adjacent cells. (B1) Higher-magnification image of the boxed area in B. Arrows in B1 indicate points of cell–cell interaction.
