      Engineering the cellular microenvironment: Cell-derived matrices for tissue engineering and regenerative medicine

      By: , Posted on: February 27, 2020

      ?The field of tissue engineering has been transformed over the last few decades by researchers using novel methods to manipulate cells and their microenvironment. These works have shed light in the important role that the cellular microenvironment has in essential physiological and pathological events. The extracellular matrix (ECM), a network of polymeric proteins and glycoproteins that surrounds cells within tissues, is one of the most important components of this complex microenvironment. It regulates key cellular functions in the body, such as cell migration, proliferation or differentiation during wound healing. In addition, a tight control of the ECM homeostasis is fundamental for normal development of embryos and for the proper function of organs. However, a perturbation of this homeostasis can lead to the development of life-threatening pathologies, such as cancer.

      The importance of the adequate properties of the ECM on the regulation of physiological and pathological conditions, have led researchers to develop innovative and physiologically-relevant models of the ECM to investigate the mechanisms of disease progression or organ functions. Indeed, tremendous progress has been obtained in the field of bioengineered cellular microenvironments during the last years, including the construction of biomimetic matrices with pre-defined architectures mimicking some of the events occurring inside the human body, the development of implantable cell-laden biomaterials with tunable properties for controlled drug delivery, or the fabrication of decellularized tissue patches for regenerative medicine applications.

      The 2 volumes entitled Cell-Derived Matrices published within the Serial Methods in Cell Biology focuses in this field of research: engineering the cellular microenvironment. These volumes provide a detailed description and step-by-step methods of the current methodologies, emerging methods, and the most recent developments in the field of cell-derived matrices. The volumes include the contributions of world-recognized leaders in the field of bioengineering, biofabrication, tissue engineering and regenerative medicine, who also provide important forward-looking visions and research directions. The 2 volumes describe the latest advancements in the methods and technologies that enable the accurate fabrication, manipulation, quantification, monitoring, and imaging of the ECM. In particular, Part A provides a collection of chapters describing step-by-step methods surrounding the use of three-dimensional cell-derived matrices for tissue engineering applications. Part B compiles a selected list of chapters describing the most recent developments in the decellularization of tissues for regenerative medicine applications. In both Parts A and B, biochemical, biophysical, and cell biological approaches are presented along with sample results.

      Overall, we are convinced that the content of these volumes will help the scientific community to shed light on fundamental mechanisms of cell biology. This will provide new avenues for the development of better drugs, for the early diagnosis or prevention of diseases, or for the regeneration of tissues.
