TISSUE ENGINEERING FOR THE DEVELOPMENT OF THREE-DIMENSIONAL INVITRO MODELS OF HUMAN MUCOSAE
2014
Traditional two-dimensional (2D) cell cultures only partially reflect the morpho-molecular pattern of human cells in tissues, and they are also unable to fully mimic the complexity of the in vivo microenvironment. Cell development in in vivo systems differs significantly from classical 2D cell culture models, especially with regard to the morphology, growth kinetics, gene expression and the degree of differentiation. Tissue engineering allows the reproduction of tissues by cell seeding on biocompatible scaffolds, to form a homogenous ...
Characterization of a novel three-dimensional outgrowth model of human bronchial mucosa
2011
Recently it has been hypothesized that a reactivation of the epithelial-mesenchymal trophic unit (EMTU) of the respiratory mucosa, caused by extensive epithelial damage, may be responsible for the pathogenesis of asthma. However, most research on this subject so far has been limited by the unavailability of in vitro models correctly mimicking the three-dimensional architecture of the properly differentiated human bronchial mucosa. For this reason, we have developed a novel 3D outgrowth model, obtained from bronchial biopsies and composed of both human bronchial epithelial cells (goblet and columnar cells) and fibroblasts with their basement membrane. Here we present the preliminary data obt…
