"Miniature Human Heart on a Chip Mimics Real Heart's Beat"
Researchers have developed a new 'heart-on-a-chip' model using matured human induced pluripotent stem cells (hiPSCs) that beats like a human heart, offering a more accurate way to test the safety of cancer treatments and other drugs. The chip, featuring heart and blood vessel cells on a flexible silicone material, simulates blood flow and mechanical heart movements to predict potential toxicity issues. This advancement could reduce reliance on animal models for drug testing and provide insights into heart disease development and treatment.
