Abstract The responses of dendritic cells (DCs) to the mechanical microenvironment caused by implanted materials are highly correlated to the host immune responses and largely determines the outcome of tissue regeneration [1,2]. In the early stage of the inflammations following injury or implantation, a large amount of fibrin would deposit around the implanted materials and form a microporous fibrous-liked network structure, which can provide mechanical microenvironment with different spatial confinement in dimensions for following recruited DCs. Herein, we have established a useful model by salmon fibrin to mimic the deposited fibrin matrix and found that DCs cultured on or in fibrin… More >

Abstract As potent antigen presenting cells, dendritic cells (DCs) are utilized to deliver the signals essential for the initiation of immune responses. The motility of DCs is crucial for migration of immature DCs (imDCs) in peripheral tissue and the interaction between mature DCs (mDCs) and naïve T cells in the secondary lymph node. From biomechanical viewpoint, the deformability of cells is necessary for their motility. Deformation of cells can be divided into active deformation (e.g. chemotaxis) and passive deformation (e.g. migration under shear stress of blood flow). However, there is no detailed study on the deformability of DCs including imDCs and… More >
