What's Happening?
A new study has developed a mechanodynamic brain-on-chip (BoC) technology to study human stem cell-derived neuronal networks. This innovative approach uses microfabrication techniques to create a chip that mimics the mechanical environment of the human brain. The BoC allows for the cultivation of neurons in both 2D and 3D models, providing insights into neuronal morphology and synapse formation. The study employed immunostaining techniques to characterize neurons and synapses, using markers such as MAP2 and SMI312. The BoC technology also enables the application of mechanical stimuli to neuronal cultures, simulating conditions like stroke and hypertension.
