Abstract
Description
technical field The invention relates to a cell culture system comprising a three-dimensional biocompatible framework (dreidimensional biokompatible Gerüststruktur) and nanoparticles (Nanopartikel). The invention also relates to a method for preparing such a cell culture system and a method for culturing cells using said cell culture system. Background technique Cells in vivo are surrounded by a complex, dynamic microenvironment consisting in particular of extracellular matrix (Matrix, ECM), growth factors (Wachstumsfaktoren), cytokines (Cytokinen) and neighboring cells (benachbarten Zellen). The extracellular matrix exists in a total of four basic tissue types, namely epithelial, muscular, neural, and connective and supportive tissues. In addition to their function as a kind of supporting framework, which has long been considered their main function, the ECM is primarily used for interactive signal exchange through the cell's transmembrane receptors. Due to this form of c...
