Collagen VII, the major component of cutaneous anchoring fibrils is expressed at a low level by normal human keratinocytes and fibroblasts in vitro. In cocultures of these two cell types, signals from fibroblasts enhance expression of collagen VII by keratinocytes and vice versa. In this study, the effects of a possible mediator of such a stimulation, transforming growth factor-beta (TGF-beta),...
In the unsutured partial thickness penetrating wounds of the cornea, the epithelium migrates over the wounded stromal surface prior to the onset of stromal regeneration. To determine the possible affects of the epithelial ingrowth on the organization of the stromal scar tissues, the healing of unsutured and sutured wounds was compared immunohistochemically. Immunostaining patterns for fibronect...
The growth pattern of human epidermal cells, fibroblasts or Swiss mouse 3T3/J2 fibroblasts cultured upon the extracellular matrix (ECM) derived from small intestinal submucosa (SIS) was evaluated. The cell/SIS composites were grown submerged, then maintained in air/liquid interface for 2, 7, 10 or 14 days. The presence of differentiation-related keratins 10, 14 and 16, FN, laminin, collagen typ...
Collagen VII is the major structural constituent of anchoring fibrils in the skin. It is synthesized as a procollagen that is larger than the collagen deposited in the tissue. In this study, we investigated the conversion of procollagen VII to collagen VII in human skin and in cutaneous cells in vitro and identified the propeptide using domain-specific antibodies. For this purpose, two bacteria...
PURPOSE Deficiencies in enzymes involved in proteoglycan (PG) turnover underlie a number of rare mucopolysaccharidoses (MPS), investigations of which can considerably aid understanding of the roles of PGs in corneal matrix biology. Here, the authors analyze novel pathologic changes in MPS VII (Sly syndrome) to determine the nature of PG-collagen associations in stromal ultrastructure. METHODS...
