FIG. 3.

Hematoxylin and eosin staining of μDERMs and control tissues. To evaluate the effects of FN and topography on epithelialization, the epidermal thickness was measured on μDERMs without FN cultured for 3 days at the air/liquid (A/L) interface (A and B, respectively), μDERMs with FN cultured for 3 days at the A/L interface (C and D, respectively), and 7 days at the A/L interface (E and F) and compared to keratinocytes cultured on decellularized dermis (DED) cultured for 3 or 7 days at the A/L interface (G and H, respectively) as well as foreskin and breast control tissues (I and J, respectively). Scale bars=50 μm. Color images available online at www.liebertpub.com/tea
