Summary

Story summary

Michigan State University (MSU) researchers developed the first human heart organoids that replicate atrial fibrillation.
The organoids, created from human stem cells, enable study of heart development, diseases, and drug responses affecting 60 million people.
Led by Aitor Aguirre at Michigan State University, the team showed inflammatory molecules caused irregular heartbeats.
The findings are published in Cell Stem Cell and address a 30-year gap in new A-fib treatments.
