Remote-Controlled Magnetic Stimulation of Cell-Based Bioengineered Tissues for In Situ Bone Regeneration.

The native cell microenvironment activates signaling pathways through mechanotransduction mechanisms, influencing cells' physiological and functional outcomes. Magnetic fields are explored to manipulate these environments, and magnetic nanoparticles (MNPs) are highlighted as nano-instructive agents capable of activating key signaling pathways, presenting exciting possibilities in tissue engineering. Still, the ability to precisely control the assembly and differentiation of stem cells within a dynamically responsive microenvironment, crucial for effective tissue regeneration, remains unexplored.
