In-vitro method for identifying and analysing ion channels and/or water channels and/or receptors of signal transduction using a three-dimensional cell culture model of the sweat gland

Abstract

The present disclosure relates to an in-vitro method for identifying and analyzing ion channels and/or water channels and/or receptors of signal transduction, in which a three-dimensional sweat gland equivalent having from about 500 to about 500,000 sweat gland cells and a diameter of from about 100 to about 6,000 μm is firstly provided and then any ion channels and/or water channels and/or receptors of signal transduction present in this equivalent are infected and analysed. In a further method step c) the influence of test substances on the proteins identified previously in step b) is examined. Since the three-dimensional sweat gland equivalents used in step a) comprise differently differentiated cells and portray the in-vivo situation well, the measurement data obtained with the in-vitro method as contemplated herein can be transferred well to the in-vivo situation.
