Tissues are ensembles of similar or compatible types of animal or plant cells that together carry out a specific function. In the human body there are four categories of tissues: epithelial, connective, nervous and muscle.
The development of embryoid bodies that are responsive to external stimuli is of great interest in tissue engineering. Here, the authors culture embryonic stem cells with magnetic nanoparticles and show that the presence of magnetic fields could affect their aggregation and differentiation.
3D-printed grafts with geometrically designed and endothelialized vasculature rescue the perfusion of distal tissues in rodent models of hind limb ischaemia and myocardial infarction, preventing capillary loss, muscle atrophy and loss of function.
