PDGFRα+DPP4+ Fibroblasts‐Macrophage Crosstalk Induces Orbital Fibrosis in Treatment‐Resistant Thyroid Eye Disease via the GAS6‐AXL Pathway

Advanced Science, EarlyView.
This study elucidates macrophage‐induced orbital fibrosis in TED via the GAS6‐AXL pathway, a treatment‐resistant disorder lacking non‐surgical therapies. Using a novel patient cell‐derived orthotopic animal model of orbital fibrosis for TED, we repurpose an existing fibrosis therapy, addressing the absence of stable models and offering a potential ...

Nonlinear Optical Corneal Crosslinking, Mechanical Stiffening, and Corneal Flattening Using Amplified Femtosecond Pulses. [PDF]

, 2019
Purpose:We have shown that nonlinear optical corneal crosslinking (NLO CXL) and stiffening can be achieved in ex vivo rabbit corneas using an 80-MHz, 760-nm femtosecond (FS) laser, however the required power was beyond the American National Standard ...

Optimizing biophysical properties of cellular niches to enhance stem cell‐derived extracellular vesicle function in musculoskeletal regeneration

BMEMat, EarlyView.
Extracellular vesicles (EVs) derived from stem cells show promise for applications in regenerative medicine, but their scalability and yield remain challenges. This review explores the approaches for biophysical modulations within cell niches on EV properties, discusses the current clinical application of EVs, and provides an outlook on the existing ...
