Priming Chondrocytes during Expansion Alters Cell Behavior and Improves Matrix Production in 3D Culture

[Osteoarthritis And Cartilage] Chondrocytes were isolated from juvenile bovine knee joints and cultured with (primed) or without (unprimed) a growth factor cocktail. Gene expression, cell morphology, cell adhesion, cytoskeletal protein distribution, and cell mechanics were assessed.

Recent Advances in Production of Sustainable and Biodegradable Polymers from Agro-Food Waste: Applications in Tissue Engineering and Regenerative Medicines

[International Journal Of Biological Macromolecules] Investigators highlight recent advances in the development of biopolymers from agro-food waste and their potential for future tissue engineering and regenerative medicine applications, including drug delivery, wound healing, tissue engineering, and more.

Extracellular Matrix-Trapped Bioinspired Lipoprotein Prolongs Tumor Retention to Potentiate Antitumor Immunity

[Advanced Materials] Researchers designed a protease-activated fibronectin (FN1) and/or tenascin C (TNC) binding peptide (FTF) and propose an ECM-trapped bioinspired lipoprotein that could be preferentially captured by the TNC and/or FN1 for tumor retention, and then be responsively dissociated from the matrix to potentiate the antitumor immunity.

Molecular Profiling of Human Substantia Nigra Identifies Diverse Neuron Types Associated with Vulnerability in Parkinson’s Disease

[Science Advances] Investigators identified cell clusters representing various neuron types, glia, endothelial cells, pericytes, fibroblasts, and T cells and investigated cell type–dependent alterations in gene expression in Parkinson's disease.

A Highly Efficient Cell Culture Method Using Oxygen-Permeable PDMS-Based Honeycomb Microwells Produces Functional Liver Organoids from Human Induced Pluripotent Stem Cell-Derived Carboxypeptidase M Liver...

[Biotechnology And Bioengineering] Investigators developed a highly efficient method for generating functional liver organoids from hiPSC-derived carboxypeptidase M liver progenitor cells, using a microwell structure, and enhanced maturation through direct oxygenation in oxygen-permeable culture plates.

Investigation of the Effects of T-2 Toxin in Chicken-Derived Three-Dimensional Hepatic Cell Cultures

[Scientific Reports] To gain more accurate understanding, the effects of T-2 toxin were investigated in the present study in chicken-derived 3D primary hepatic cell cultures. 3D spheroids were treated with three concentrations of T-2 toxin for 24 hours.
