An Open‐Source Pipeline for Calcium Imaging and All‐Optical Physiology in Human Stem Cell‐Derived Neurons

open access: yesAdvanced Science, EarlyView.
This work introduces an open‐source all‐optical platform for functional phenotyping of human stem cell‐derived neurons. The system integrates optogenetics, calcium imaging, automated acquisition, and analysis to resolve single‐cell and network activity, enabling longitudinal measurements, disease modeling, and pharmacological screening in preclinical ...

A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions

open access: yesAdvanced Science, EarlyView.
This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...

Single‐Cell Atlas of Subchondral Bone Marrow Lesions Reveals Proteostasis Dysfunction as a Druggable Mechanism for Early Osteoarthritis

open access: yesAdvanced Science, EarlyView.
This study reveals that abnormal mechanical stress downregulates the expression of HSP70 and impairs proteasome function in osteoarthritic bone cells, leading to misfolded collagen I accumulation and ER stress. When intracellular proteostasis capacity is exceeded, USP19 mediates the secretion of misfolded proteins into the extracellular space ...
