3D Mechanical Confinement Directs Muscle Stem Cell Fate and Function

Advanced Biology, EarlyView.
This study reveals that the physical environment surrounding muscle stem cells (MuSCs) plays a crucial role in their function. Using a 3D hydrogel system, it shows that increased confinement preserves MuSC stemness by limiting activation, proliferation, and differentiation.

Elasticity of Diametrically Compressed Microfabricated Woodpile Lattices

Advanced Engineering Materials, EarlyView.
Modulus–porosity relationship is derived for woodpile lattices with struts under diametrical compression. The formula presented here that Young's modulus is proportional to the square of the volume fraction E˜ρ2$E \sim \left(\rho\right)^{2}$ is shown to be consistent with computations and laboratory experiments on 3D‐printed samples.
