Biologists build the first standardized toolkit for measuring how lab-grown heart tissue actually contracts

Researchers created an open-source pipeline that measures 16 different properties of engineered cardiac tissue — how it deforms, how synchronized it is, whether it contracts uniformly. Until now, every lab measured these things differently, making it impossible to compare results across experiments or institutions.

Heart tissue engineering has been a measurement Wild West. Each lab developed its own metrics, making reproducibility impossible and preventing the field from building cumulative knowledge about what makes engineered tissue work. This toolkit standardizes that measurement across institutions. What matters next is whether other labs actually adopt it — adoption of open-source standards in biotech is historically slow, even when they're clearly better.
