Abstract
The invention provides a process for producing a three-dimensional tissue by cultivating eucaryotic cells by introducing the cells into a matrix and cultivating the cells within the matrix in a cell culture medium within a cell culture vessel under controlled dissolved oxygen conditions of the cell culture medium. The matrix contains a support containing an optical oxygen sensor, which is an oxygen-sensitive dye, which upon irradiation with an excitation wavelength changes its emission characteristics in dependence on the dissolved oxygen concentration in the surrounding medium, including a dye phosphorescing upon irradiation of an excitation wavelength, which phosphorescence is quenched by dissolved oxygen.
