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.

Manufacture of Soft‐Hard Implants from Electrospun Filaments Embedded in 3D Printed Structures

Macromolecular Bioscience, Volume 22, Issue 12, December 2022., 2022
The surgical repair of rotator cuff tendon tears can fail due to use of suture anchors that do not promote healing of the native tissues. A simple manufacturing approach is presented here that combines electrospun filaments and 3D printing to achieve biphasic scaffolds using biocompatible materials: a soft polydioxanone cuff embedded in a porous ...

Mechanism of spindle pole organization and instability in human oocytes

Science, 2022
Human oocytes are prone to assembling meiotic spindles with unstable poles, which can favor aneuploidy in human eggs. The underlying causes of spindle instability are unknown.
