Figure 2. Effect of orientation on the normalized take rate (combined graft survival and wound area) for wounds implanted with porcine acellular dermal matrix (ADM) and split-thickness autografts (STSG; Xeno-ADM) and rat ADM and STSG (Allo-ADM). ADMs were implanted into full-thickness wounds either with the papillary side or the reticular side of the dermis oriented superficially (toward the overlying STSG). Shown are means ± standard error (n = 6).
