Article Abstract
To obtain extracellular matrix (ECM) of umbilical cord multipotent mesenchymal stromal cells (UC-MSCs), six decellularization protocols were used, based on physical (freeze/thaw) and chemical (Triton-X100, CHAPS, SDS, and NP-40) methods. The quality of decellularization was assessed using phase-contrast and fluorescence microscopy, quantitative image analysis was performed as well. It was shown that protocols based on CHAPS/NH4OH and Triton X-100/NH4OH are optimal for decellularizing UC-MSC layers and provide high-quality ECM. The SDS-based protocol may be useful when certain requirements to matrix structure are specified. The presented data will be in demand for the development of biomedical products.

Introduction: The Zika virus (ZIKV) envelope (E) protein is critical for viral replication and host interactions. Although glycosylation of the E protein is known to influence viral infectivity and immune evasion, the specific functional roles of E protein glycosylation in ZIKV infectivity in mosquito cells remain unclear.
Methods: In this study, we generated a deglycosylation mutant ZIKV with a T156I substitution in the E protein and investigated its effects on viral replication and viral-host interactions in mosquito C6/36 cells.
Engineered nanofiber scaffolds prime chromatin reorganization to sensitize cells for long-term and low-dose chemical hazard detection.

Fast and early detection of low-dose chemical toxicity is a critical unmet need in toxicology and human health, as conventional 2D culture models often fail to capture subtle cellular responses induced by sub-toxic exposures. Here, we present a bioengineered three-dimensional (3D) electrospun nanofibrous scaffold composed of polycaprolactone that enhances chromatin accessibility and primes fibroblasts for improved sensitivity to low-dose chemical stimuli in a short period. The scaffold mimics the extracellular matrix, providing topographical cues that reduce cytoskeletal tension and promote nuclear deformation, thereby increasing chromatin openness.

In the cardiovascular system, elastic fibres exert a fundamental role providing the long-range elasticity required for physiological functions. Elastic fibres are complex in composition and structure containing, in addition to elastin, a wide range of matrix components, such as microfibrillar proteins, calcium-binding proteins and glycosaminoglycans. Changes in composition and/or structure can affect the biomechanics of the tissue as well as the intrinsic affinity of elastin for Ca ions.

Neurological disorders are complex conditions characterized by impairment of the nervous system, affecting motor, cognitive, and sensory functions. Current treatments meet substantial obstacles, primarily due to the difficulty of transporting drugs across the blood-brain barrier and ineffective therapy for nerve regeneration. Emerging technologies, such as electrospinning, offer innovative solutions to overcome these challenges.

This study aimed to develop an acellular dermal matrix derived from tilapia skin and evaluate its potential as a bioscaffold for skin wound repair. Structural and compositional changes before and after decellularisation were assessed through histological staining, electron microscopy and immunological analysis. The matrix exhibited low immunogenicity, preserved extracellular matrix architecture and retained key bioactive components.
