Researchers Create First Human Heart Cells That Can Be Paced With Light
the heart cells contract in concert with the light. the first time engineered human heart cells that can be paced with light using a technology called optogenetics. light-based pacemakers and genetically matched tissue patches that replace muscle damaged by a heart attack. inject these engineered light-sensitive cells into the faulty heart and pace them remotely with light, possibly even from outside of the heart.researchers are often seeking to measure electric response in the heart.  It might lead to new insights for various neuronal, musculoskeletal, pancreatic and cardiac disorders, including depression, schizophrenia, cerebral palsy, paralysis, diabetes, pain syndromes and cardiac arrhythmias
