Matrix Stiffness Directs Stemness Signatures in Breast Cancer

Advanced Healthcare Materials, EarlyView.
We built lab‐grown breast cancer models to study how the stiffness of the tumor's surroundings influences cancer behavior. Softer environments encouraged more stem‐like, drug‐resistant cells, while stiffer ones kept cells more differentiated. These findings show that tissue mechanics drive cancer diversity and drug resistance, offering new insights for

Gellan Gum Fluid Gel System for Controlled‐Delivery of Cytokine‐Licensed MSC‐EVs to Enhance Corneal Repair in Limbal Stem Cell Deficiency

Advanced Healthcare Materials, EarlyView.
Gellan gum fluid gel (FG) enables controlled ocular delivery of mesenchymal stromal cell (MSC)‐derived extracellular vesicles (EV). Its shear‐thinning, solid‐liquid‐solid rheology ensures prolonged ocular retention. Sustained MSC‐EV release (∼18% in 6 hrs) supports effective EV ocular delivery.

Rheology and Processing of Novatein Thermoplastic Protein

, 2010
Biopolymers have become suitable alternatives to petro-chemical polymers as they can biodegrade and are considered environmentally friendly. Novatein Thermoplastic Protein (NTP) is a newly developed plastic material using bovine bloodmeal.

The Rheology of Soil Pastes

, 1930
An apparatus is described for investigating the behavior of soil‐water and clay‐water pastes while flowing through narrow glass tubes. The nature of the curves relating rate of flow to shearing stress is discussed.

Mechanically Programmable DNA Hydrogel Microparticles for 3D Cellular Systems

Advanced Materials, EarlyView.
DNA hydrogel microparticles are designed to exhibit controllable viscoelasticity and stiffness across three orders of magnitude from 30Pa$30 \,\mathrm{Pa}$ to 6.5kPa$6.5 \,\mathrm{kPa}$. They are uptaken into fibroblast spheroids where they are actively remodeled by cellular forces depending on their mechanical properties.
