Protein‐Polymer Dynamic Hydrogels Utilizing Native Ligand Binding for Injectable Therapeutic Delivery and 3D Printing

Advanced Healthcare Materials, EarlyView.
Dynamic nanocolloidal hydrogels were synthesized via the co‐assembly of ligand‐modified spheroidal hyperbranched poly(glycerol) (HPG) and soluble albumin nanoparticles (SANs). Co‐assembly occurred through self‐association of the HPG, as well as its interaction with SANs via native ligand binding.

An Antimicrobial, Cell‐Adhesive, and Growth Factor‐Producing Living Material Engineered From Bacillus subtilis Biofilms for Wound Healing

Advanced Healthcare Materials, EarlyView.
Bacillus subtilis is engineered to produce cell‐adhesive biofilms by functionalization of its biofilm scaffold protein TasA with a cell‐adhesion sequence. Living bacteria within the biofilm are also engineered to secrete growth factors and natively produce antimicrobial peptides (AMPs), resulting in a cell‐adhesive, antimicrobial, and growth factor ...

Effect of transglutaminase cross-linking on the in vivo digestion and absorption characteristics of collagen gel

Collagen and Leather
This work was conducted to prepare the transglutaminase (TGase) cross-linked collagen gel (CGL) by using pork skin as raw material, and to systematically investigate its digestive and absorptive properties and serum metabolism regulation in mice.

Macrophage–Fibroblast Crosstalk Governs Tumor Mechanics, as Revealed by Spatiotemporal Force Mapping in 3D Spheroids

Advanced Healthcare Materials, EarlyView.
This study shows crosstalk among tumor cells, fibroblasts, and macrophages alters the physical forces inside 3D tumor spheroids. Incorporating deformable microparticles in 3D tumor spheroids, the researchers mapped mechanical stresses spatially and with respect to tumor growth (temporally).

The Role of Viscoelasticity in Heterogeneous Glioblastoma Stem Cell Invasion in Biomimetic 3‐Dimensional Hydrogels

Advanced Healthcare Materials, EarlyView.
The role of viscoelasticity in the invasion of heterogeneous glioblastoma stem cells (GSCs) was investigated with GSCs categorized into subgroups based on molecular profile, as Reactive, Invasive, or Constructive using viscoelastic biomimetic hyaluronan‐oxime hydrogels.

Anti‐Inflammatory and Neuroactive Effects of Polymer‐Coated Iron Oxide Nanoparticles Functionalized With Interleukin 4 for Spinal Cord Injury

Advanced Healthcare Materials, EarlyView.
Polymer‐coated IONPs functionalized with IL‐4 display respective neuroactive and anti‐inflammatory actions on neural progenitor cells and macrophages/microglia in vitro. When examined chronically in a rat experimental model of spinal cord injury, rGO scaffolds carrying these nanosystems adequately integrate into the lesion, significantly reduce ...

Topically Delivered Treg‐Attracting Microparticle‐Hydrogel Composites Recruit Regulatory T Cells and Limit Cardiac Injury After Severe Ischemia

Advanced Healthcare Materials, EarlyView.
CCL22‐releasing PLGA microparticles (MP) suspended in topically applied hydrogels (HEART) establish a sustained chemokine gradient at the injured myocardium. HEART recruits CCR4+ regulatory T cells, reduces infarct size and graft fibrosis, and improves cardiac function.
