METHODS FOR IMPLANTING CELLS

摘要

A method for implanting cells onto a prosthesis includes the steps of: (a) providing a prosthesis including a porous tube, where at least 25% of the pores on the inner surface of the tube have diameters of more than about 40 mum, at least 25% of the pores on the outer surface of the tube have diameters of less than about 30 mum, and the tube includes a substantially continuous layer of a biocompatible material; (b) contacting the prosthesis with a suspension of cells; and (c) providing a pressure differential between the inner surface and the outer surface, whereby the cells are retained in the pores of the inner surface. A method for obtaining an endothelial cell culture from a blood sample involved:(a) obtaining a sample for mononuclear cells from a blood sample; and (b) culturing the sample of mononuclear cells, without further cell separation, on a cell adhesive polymer-coated solid support in the presence of endothelial growth factors.
