    摘要: Methods of forming soft connective tissue compositions such as skin equivalents, compositions made by the methods and their uses. 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: Baldness or hair loss has been treated using pharmaceutical drugs and/or hair transplant surgery. The present invention relates to an improved method for treating baldness. In one aspect, there is provided a method for inducing hair follicle formation in a dermal layer lying beneath an outer skin surface, comprising delivering inductive dermal sheath cells and/or inductive dermal papilla cells directly into the dermal layer using a controlled delivery device. Delivery of the inductive cells need not be into pre-existing pores. Use of a controlled delivery device for the treatment of baldness is a further aspect of the invention.

    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.
