FIG. 6.

Cell images and distribution of injection seeded scaffold. (A) Two dimensional (2D) center slice showing minimal cell presence on the upper surface down to the center, with most cells appearing in the area below the center of the scaffold toward the bottom portion of the scaffold. (B) 3D distribution shows a high density of cells along the injection route on the upper corner of the scaffold descending to a high-density area on the bottom portion of the scaffold representing the injection point. (C) Vertical distribution of the cell density on a cross-sectioned injection-seeded scaffold (n = 1). (D) Cell density remains low from the upper exterior surface to the center of scaffold, increasing past the center at the injection point and reaching a maximum at the bottom surface of the scaffold. Vertical lines denote ± 1 standard deviation; n = 3. Color images available online at www.liebertonline.com/ten.
