Comparison of (a) normal and (b) regenerated skin. The dermal-epidermal junction of regenerated skin shows capillary loops inside the rete ridges. Neither rete ridges nor capillary loops form in scar. Presence of rete ridges is one of two major features that distinguish intact and regenerated skin from scar. Another distinguishing feature is presence of quasirandomly oriented collagen fibers in the intact and regenerated dermis, rather than a highly aligned stroma, as in dermal scar. (C. C. Compton et al., Organized skin structure is regenerated in vivo from collagen-GAG matrices seeded with autologous keratinocytes, J. Invest. Dermatol.,110:908–916, 1998)
