Building Heart Tissue That Beats: Engineered Tissue Closely Mimics Natural Heart Muscle

On it, the researchers grow actual workouts heart cells. To make sure the cells form the right structure, Khademhosseini's lab uses 3-D printing and microengineering techniques to create patterns in the gels. These patterns coax the cells to grow internet the way the researchers want them to. The result: small patches of heart muscle cells neatly lined up that beat in synchrony within the grooves click here. formed on these elastic substrates. These micropatterned elastic hydrogels can one day be used as cardiac patches. Khademhosseini's group is now moving into tests with large animals. They are also using these elastic natural hydrogels for the regeneration of other tissues such as blood vessels, skeletal muscle, heart valves and vascularized skin.
