Self‐Healing Hydrogel‐Enabled Modular Assembly of Bilayered Skin Construct for Hair Follicle Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Self‐healing assembly of two cell‐laden hydrogel layers creates a biomimetic skin construct that restores both dermal and epidermal functions, resulting in accelerated wound healing and enhanced hair follicle regeneration in a full‐thickness skin wound model. ABSTRACT Alopecia remains a pervasive clinical challenge, largely owing to the limited ability

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

open access: yesAdvanced 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 ...

Neopterin, β2-Microglobulin and Carbohydrate Antigen CA-19-9 in Sporadic Adult Amyotrophic Lateral Sclerosis

open access: yesPteridines, 1993
In 38 patients diagnosed as adult sporadic amyotrophic lateral sclerosis (ALS), and negative for relevant anti -ganglioside, anti-borrelia or anti-Boma disease virus antibodies, we determined serum concentrations of neopterin, ~rmicroglobulin ...

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

open access: yesAdvanced 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.

Development of an indirect and a dot ELISA to detect antibodies to porcine pseudorabies virus in Argentina [PDF]

open access: yes, 2023
Indirect and dot enzyme linked immunosorbent assays (ELISAs) were developed to detect antibodies to pseudorabies virus (PRV) in serum samples of 321 pigs. The Argentine CL 15 PRV strain was used as the source of virus.

Atom‐Efficient Cerium‐Based Molecular Cages as Biocompatible Reactive Oxygen Scavengers

open access: yesAdvanced Healthcare Materials, EarlyView.
Discrete mixed‐valent cerium molecular cages organize accessible redox centers within confined coordination environments and scavenge superoxide, hydrogen peroxide, and hydroxyl radicals. Encapsulation of the lead cage in an ROS‐responsive DTP nanoplatform enables lesion‐associated delivery, attenuates macrophage oxidative stress and inflammation, and ...

Bioprinted Stiffness‑Tunable Pancreatic Microniches to Decode Early Tumor Initiation Mechanisms

open access: yesAdvanced Healthcare Materials, EarlyView.
Stiffness‐tunable GelMA microniches generated by microvalve bioprinting preserve wild‐type acinar identity while revealing a nonlinear, Kras‐dependent response to matrix mechanics. Intermediate stiffness promotes acinar‐to‐ductal metaplasia and proliferation, defining a permissive mechanical window.

A 3D‐Printed Model of Human Lactation

open access: yesAdvanced Healthcare Materials, EarlyView.
Breastfeeding supports infant and maternal health, yet in vitro models that mimic human lactation remain scarce. Here, light‐based 3D printing creates high‐resolution, alveoli‐inspired microwells that guide breast cells into polarized microtissues. The printed scaffolds embed slow‐release prolactin microcrystals to deliver hormonal cues, enabling human

A Novel 3D Model Co‐Culturing Breast Cancer Cells in Direct Contact with Patient‐Derived Mature Adipocytes Demonstrates Cell‐Type Specific Alterations in Phenotype and Chemosensitivity

open access: yesAdvanced Healthcare Materials, EarlyView.
A novel 3D GelMA co‐culture model enabled sustained direct contact between patient‐derived mature adipocytes and breast cancer cells, revealing subtype‐specific interactions. MDA‐MB‐231 co‐culture caused adipocyte perilipin‐1 loss and reduced chemotherapy responsiveness, while MCF7 cells showed partial epithelial‐mesenchymal transition; both cell lines
