Metatissue® is focused on designing and manufacturing human protein-based products that find application in cell culture, tissue engineering and regeneration and disease modelling. Our biomaterials provide realistic microenvironments for cell culture allowing for greater cell-to-cell and cell-to-matrix interaction resemblance, thereby increasing the accuracy of in vitro studies. The extracellular matrix of living tissues is composed by a great diversity of structural proteins and bioactive factors. For this reason, mimicking its function in vitro continues to be a big challenge. Our strategy is to use ethically sourced human proteins to produce the next-generation of xeno-free biomimetic 3D cell culture platforms.
