Barcodes uncover early blueprints of our cellular origins

Walter and Eliza Hall Institute
Peer-Reviewed Publication

A landmark study by WEHI scientists has shed new light on one of the most fundamental mysteries of biology: how cells divide and grow into the complex structures that make up our bodies.

The study has produced a sophisticated and leading new technology for tracking cells very early during embryo development, as they divide, migrate and specialise into the organs, tissues and systems that keep us alive.

The innovative tech, called LoxCode, provides each cell in a genetically engineered mouse with one of billions of individual DNA barcodes, allowing them to be tracked in unprecedented detail.

Heart valve developed at UC Irvine shines in early-stage preclinical testing

University of California - Irvine
Peer-Reviewed Publication

UC Irvine researchers designed and developed a minimally invasive replacement pulmonary heart valve.

Created for pediatric patients, the device can be expanded as children grow, eliminating the need for multiple surgeries.

The team successfully conducted laboratory and early-stage animal feasibility testing of the implant, crucial steps toward approval for human use.
