摘要： Tissue equivalents are produced by applying a solution of collagen without cells to a permeable membrane, gelling to produce a collagen gel on the membrane, applying a mixture of collagen and a contractile agent to the collagen gel, gelling the mixture and allowing the resultant gel to undergo radial contraction which is controlled by the collagen gel on the membrane. A suitable contractile agent is fibroblast cells. A skin tissue equivalent is produced by disposing human epidermal cells on the contracted collagen gel and allowing epidermalization to occur. A nutrient medium can be supplied to the cells. An absorbent member may be disposed adjacent the permeable membrane opposite the collagen gel on the membrane. The permeable membrane can be the bottom of an inner well disposed in an outer well for containing a nutrient medium in contact with the membrane. The nutrient medium may be contained in the outer well in an agarose gel in contact with the membrane.

In particular, a method of forming a connective tissue equivalent, comprising the steps of: (i) incubating collagen-producing cells in or on a support matrix; (ii) inducing and/or enhancing collagen production by the collagen-producing cells to form a collagenous construct and degradation and replacement of the support matrix; (iii) freeze-drying the construct; and (iv) re-populating the freeze-dried construct with collagen-producing cells and/or epithelial cells and/or endothelial cells and/or mesenchymal cells, thereby forming a connective tissue equivalent, wherein: (a) the collagen-producing cells are substantially fibroblasts; for example human neonatal dermal fibroblasts; (b) the support matrix is a provisional support matrix in which the support matrix is a fibrin matrix, for example formed by thrombin-mediated polymerisation of fibrinogen; and (c) as a result of the collagen production by the collagen-producing cells the provisional fibrin support matrix is digested by the cells and is replaced by collagen, thereby essentially replacing the provisional fibrin matrix with a collagen matrix synthesised in situ by the cells.

摘要： An air-bearing center-guiding apparatus 10 and a method are disclosed for supporting and laterally center-guiding thin flexible webs of paper or plastic under 15 mils in thickness. The apparatus comprises a web support and guide member 22 having an inner surface and an outer web-facing surface. Parallel rows of elongated spaced-apart guide apertures 34 extend longitudinally along edge regions of the web. Each guide aperture 34 is formed from a cylindrical opening in the web support and guide member 22 and extends substantially perpendicular to the web. Within each aperture a flat-sided dowel 60 is mounted to define a flow passage shaped in cross-section like a segment of a circle 62. Each circular-segment guide aperture 34 has a straight side 54 and a curved side 52 for directing a jet of air against the web edge 56. A plurality of the circular-segment guide apertures 34 develop a guiding force for holding lateral movement of the web to plus or minus 0.001 inch (0.0254 mm). A row of web-support apertures 32, separate from the guide apertures 34, is provided between the rows of guide apertures 34 to form an air bearing for supporting the web.

摘要： An air-bearing center-guiding apparatus is disclosed for supporting and laterally center-guiding thin, flexible webs of paper or plastic under 15 mils in thickness. The apparatus comprises a web support and guide member 10 having an inner surface 58 and an outer web-facing surface 60. The web support and guide member 10 comprises a base member 14 for supporting an inner ring 22, an end cap 38, and a center ring 28 interposed therebetween. Parallel, circumferentially extending rows of circumferentially elongated and spaced-apart guide apertures 62 are provided in the web support and guide member 10 along edge regions of the web. The guide apertures 62 are formed between end surfaces 46 of the center ring 28 and interengaging end surfaces of the inner ring 22 and end cap rings 38. Each guide aperture 62 extends substantially perpendicular to the surface of the web and defines in cross-section an opening having a straight side and a curved side for directing jets of air against the web edges for developing a guiding force for holding lateral movement of the web to plus or minus 0.001 inch (0.0254 mm). A row of support apertures 56, separate from the guide apertures 62, is provided in the center ring 28 between the rows of guide apertures 62 to form an air-bearing for the web.
