Microgel-based bioink for extrusion-based 3D bioprinting and its applications in tissue engineering.

Extrusion-based 3D bioprinting is being increasingly adopted as a versatile biofabrication method for making biomimetic constructs in tissue engineering. However, the lack of ideal bioinks continues to limit its broader application. Conventional hydrogel-based bioinks typically possess a densely crosslinked nanoporous structure that hinders their ability to fully support cell behavior.

Characterization, Enrichment, and Computational Modeling of Cross-Linked Actin Networks in Transformed Trabecular Meshwork Cells.

Purpose: Cross-linked actin networks (CLANs) are prevalent in the glaucomatous trabecular meshwork (TM). We previously developed the GTM3L cell line, which spontaneously forms fluorescently labeled CLANs, by transducing GTM3, a transformed glaucomatous TM cell line, with a lentivirus expressing the LifeAct-GFP fusion protein. Here, we determined if LifeAct-GFP viral copy numbers are associated with CLANs, developed approaches to increase CLAN incidence, and computationally studied the biomechanical properties of CLAN-containing GTM3L cells.

Multi-omics analysis identified the GmUGT88A1 gene, which coordinately regulates soybean resistance to cyst nematode and isoflavone content.

Soybean cyst nematode (SCN, Heterodera glycines) is a major pathogen harmful to soybean all over the world, causing huge yield loss every year. Soybean resistance to SCN is a complex quantitative trait controlled by a small number of major genes (rhg1 and Rhg4) and multiple micro-effect genes. Therefore, the continuous identification of new resistant lines and genes is needed for the sustainable development of global soybean production.

Glial cells improve Parkinson's disease by modulating neuronal function and regulating neuronal ferroptosis.

The main characteristics of Parkinson's disease (PD) are the loss of dopaminergic (DA) neurons and abnormal aggregation of cytosolic proteins. However, the exact pathogenesis of PD remains unclear, with ferroptosis emerging as one of the key factors driven by iron accumulation and lipid peroxidation. Glial cells, including microglia, astrocytes, and oligodendrocytes, serve as supportive cells in the central nervous system (CNS), but their abnormal activation can lead to DA neuron death and ferroptosis.
