Covalent On‐Cell Conjugation of Biomaterials Through Oxidative Phenolic Coupling Regulates Stem Cell Fate via Intracellular Biophysical Programming

Advanced Functional Materials, EarlyView.
On‐cell covalent crosslinking of hydrogel matrix to the membrane of a single cell using droplet microfluidics enables mechanotransduction and influences stem cell fate. This newly established approach influences stem cell fate, independent of YAP/TAZ mechanotransduction and non‐covalent reversible binding ligands yet by various intracellular ...

Chiral Engineered Biomaterials: New Frontiers in Cellular Fate Regulation for Regenerative Medicine

Advanced Functional Materials, EarlyView.
Chiral engineered biomaterials can selectively influence cell behaviors in regenerative medicine. This review covers chiral engineered biomaterials in terms of their fabrication methods, cellular response mechanisms, and applications in directing stem cell differentiation and tissue function.

A Gym for Cells—Direct Laser Writing of Magnetic Multilayered Micro Actuators for Mechanical Stimulation of Cells

Advanced Functional Materials, EarlyView.
Surface‐attached multilayer micromagnet systems are fabricated by two‐photon crosslinking. The pillar‐shaped micro actuators consist of a soft and flexible surface‐attached cell‐repellent hydrogel layer at the bottom, acting as a hinge and a cell‐adhesive hydrophobic polymer filled with magnetic nanoparticles.

Unveiling Parkinson's Disease-like Changes Triggered by Spaceflight [PDF]

arXiv
A meta-analysis of spaceflight data from both mouse and human flights reveals a striking overlap with Parkinson's disease (PD). Parallels include: changes in gait, loss of dopamine, sustained changes in the basal ganglia, loss of tyrosine hydroxylase in the substantia nigra, and systemic mitochondrial dysfunction.

Diabetes risk and amino acid profiles: cross-sectional and prospective analyses of ethnicity, amino acids and diabetes in a South Asian and European cohort from the SABRE (Southall And Brent REvisited) Study. [PDF]

, 2015
Aims/hypothesis: South Asian individuals have an increased risk of diabetes compared with Europeans that is unexplained by obesity and traditional or established metabolic measures.

Sustained Release of Proteins Using Region‐Specific Tunable Degradability in Hydrogels through 3D Photopatterning and Complimentary Labile Bond Chemistry

Advanced Functional Materials, EarlyView.
A series of ultraviolet‐ and near‐infrared radiation sensitive photoactivatable hydrogels are developed that can be controlled spatiotemporally down to µm precisions using one‐ and two‐photon uncaging. The latent hydroxylamine‐, hydrazine‐, and amine uncaged moieties are used to photopattern a series of diverse proteins displaying complimentary ...
