Mechanically and Chemically Defined PEG Hydrogels Improve Reproducibility in Human Cardioid Development

open access: yesAdvanced Healthcare Materials, EarlyView.
Synthetic matrix metalloproteinase (MMP)‐degradable polyethylene glycol (PEG)‐based hydrogels are developed to investigate the influence of mechanical and biochemical cues on cardioid development. Matrix stiffness and cell adhesion motifs significantly regulate cardioid formation, chamber morphogenesis, contractile function, and cardioid transcriptome.

Modeling Platelet P2Y$_1$/$_{12}$ Pathway to Integrin Activation [PDF]

open access: yesarXiv
Through experimental studies, many details of the pathway of integrin $\alpha_{\rm IIb}\beta_3$ activation by ADP during the platelet aggregation process have been mapped out. ADP binds to two separate G protein coupled receptors on platelet surfaces, leading to alterations in the regulation of the small GTPase RAP1.

Investigating the inner structure of focal adhesions with single-molecule localization microscopy [PDF]

open access: yesarXiv, 2017
Cells rely on focal adhesions (FAs) to carry out a variety of important tasks, including motion, environmental sensing, and adhesion to the extracellular matrix. Although attaining a fundamental characterization of FAs is a compelling goal, their extensive complexity and small size, which can be below the diffraction limit, have hindered a full ...

Glucocorticoids Alter Bone Microvascular Barrier via MAPK/Connexin43 Mechanisms

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
Osteoporosis induced by Glucocorticoids (GCs) is a common complication of long‐term GC use in patients with inflammatory and autoimmune conditions, often leading to an increased fracture risk. A 3D bicellular endo‐osteo microfluidic platform is developed to explore pathogenic mechanisms underlying GCs‐induced osteoporosis, highlighting a novel MAPK ...

Avian neural crest cell attachment to laminin: involvement of divalent cation dependent and independent integrins [PDF]

open access: yes, 1991
The mechanisms of neural crest cell interaction with laminin were explored using a quantitative cell attachment assay. With increasing substratum concentrations, an increasing percentage of neural crest cells adhere to laminin.

Engineered 3D Kidney Glomerular Microtissues to Model Podocyte‐Centric Diseases for the Validation of New Drug Targets

open access: yesAdvanced Healthcare Materials, EarlyView.
The study introduces innovative 3D microtissues that replicate the glomerular filtration barrier of the kidney, offering a novel platform for understanding podocytopathies. These microtissues simulate the glomerulus's structure and dynamics, allowing for the modeling of podocyte injuries and drug testing.

TPMS‐Gyroid Scaffold‐Mediated Up‐Regulation of ITGB1 for Enhanced Cell Adhesion and Immune‐Modulatory Osteogenesis

open access: yesAdvanced Healthcare Materials, EarlyView.
A) SLM generates biomimetic bone scaffolds with consistent porosity but varying TPMS‐Gyroid unit cell designs (TG15, TG20, TG25, TG30). B) By enhancing the expression of ITGB1, TPMS‐Gyroid scaffolds can facilitate osteogenic differentiation in BMSCs and promote M2 polarization in macrophages.
