Researchers at the Federal University of Rio de Janeiro study scaffold-free microtissue systems for bone and cartilage repair using quantitative mechanical testing.
In this interview, Prof. Leandra Baptista discusses how microtissue stiffness, surface tension, and force response are measured to evaluate tissue strength, viability, and fusion potential. These measurements help establish mechanical benchmarks for engineered bone and cartilage constructs and guide strategies for assembling complex tissues from spheroidal building blocks.
The work highlights how microscale mechanical properties influence both tissue maturation and the ability of microtissues to fuse into larger functional constructs for regenerative medicine.
