Besides medical application as composite skin grafts, in vitro constructed skin equivalents (SEs) or organotypic co-cultures represent valuable tools for cutaneous biology. Major drawbacks of conventional models, employing collagen hydrogels as dermal equivalents (DEs), are a rather poor stability and limited life span, restricting studies to early phases of skin regeneration. Here we present an improved stabilised in vitro model actually providing the basis for skin-like homeostasis. Keratinocytes were grown on dermal equivalents (DEs) reinforced by modified hyaluronic acid fibres (Hyalograft-3D) and colonised with skin fibroblasts, producing genuine dermis-type matrix. These SEs developed a superior epidermal architecture with regular differentiation and ultrastructure, which occurred also faster than in SEs based on collagen-DEs. Critical aspects of differentiation, still unbalanced in early stages, were perfectly re-normalised, most strikingly the co-expression of keratins K1/K10 and downregulation of regeneration-associated keratins such as K16. The restriction of integrin and K15 distribution as well as keratinocyte proliferation to the basal layer underlined the restored tissue polarity, while the drop of growth rates towards physiological levels implied finally accomplishment of homeostasis. This correlated to faster basement membrane (BM) formation and ultrastructurally defined dermo-epidermal junction including abundant anchoring fibrils for strong tissue connection. Whereas the fibroblasts in the scaffold initially secreted a typical provisional regenerative matrix (fibronectin, tenascin), with time collagens of mature dermis (type I and III) were accumulating giving rise to an in vivo-like matrix with regularly organised bundles of striated collagen fibrils. In contrast to the more catabolic state in conventional DEs, the de novo reconstruction of genuine dermal tissue seemed to be a key element for maintaining prolonged normal keratinocyte proliferation (followed up to 8 wks), fulfilling the criteria of tissue-homeostasis, and possibly providing a stem cell niche.
