Lab-Grown Heart Cells That Actually Beat

You’re looking at tiny beating hearts, grown entirely in a lab. 

Marie, also known as @labskillsacademy, walks us through how scientists turn cells into induced pluripotent stem cells, also known as iPSCs, and guide them into becoming cardiomyocytes: heart cells that beat in rhythm just like yours. They’re not full hearts, but they do contract on their own making them a powerful tool for studying how real human cells respond to drugs and genetic changes, all in a dish.
