Platelets are known to improve the wound-repair capacity of mesenchymal stem cells (MSCs) by transferring mitochondria intercellularly. This study aimed to investigate whether direct transfer of mitochondria (pl-MT) isolated from platelets could enhance wound healing using a cell-based model. Wound repairs were assessed by 2D gap closure experiment in wound scratch assay using human dermal fibroblasts (hDFs). Results demonstrated that pl-MT were successfully internalized into hDFs. It increased cell proliferation and promoted the closure of wound gap. Importantly, pl-MT suppressed both intracellular and mitochondrial ROS production induced by hydrogen peroxide, cisplatin, and TGF-β in hDFs. Taken together, these results suggest that pl-MT transfer might be used as a potential therapeutic strategy for wound repair.

Tailoring surface characteristics is key to guiding scaffold interaction with the biological environment, promoting successful biointegration while minimizing immune responses and inflammation. In cardiac tissue engineering, polyvinylidene fluoride (PVDF) is a material of choice for its intrinsic piezoelectric properties, which can be enhanced through electrospinning, also enabling the fabrication of nanofibrous structures mimicking native tissue. However, the inherent hydrophobicity of PVDF can hinder its integration with biological tissues.

Background: Critical size bone defects represent a clinical challenge, associated with considerable morbidity, and frequently trigger the requirement of secondary procedure. To fill osseous gaps, multiple steps are required, such as proliferation and differentiation on the cellular level and the building of extracellular matrix. In addition, the osteogenic potential of cell-derived extracellular matrices (CD-ECM) is known to enhance bone healing.

Purpose: The aim of the study was to evaluate the toxicity of triclosan in the Danio rerio model and mammalian cells, as well as to assess its antimicrobial and antibiofilm activity against selected bacterial pathogens.
Methods: Triclosan toxicity was assessed in Danio rerio embryos in accordance with OECD Test Guideline 236: Fish Embryo Acute Toxicity (FET) Test. Cytotoxicity was evaluated in vitro using the MTT assay on human dermal fibroblasts (BJ) and rat cardiomyoblasts (H9c2).

Hypertrophic scarring (HTS) remains a critical challenge in burn care, often resulting in debilitating contractures, chronic pain, and significant psychosocial burden. While current treatment emphasizes structural repair, recent advances underscore the importance of addressing the biological drivers of fibrosis. This review synthesizes evolving strategies in burn scar prevention, highlighting tissue-engineered matrices, autologous cell therapies, and predictive molecular tools that shift care from reactive to regenerative.

Objective: Bronchopulmonary dysplasia (BPD), a prevalent chronic pulmonary disorder predominantly affecting preterm infants, is characterized by impaired lung development and persistent inflammatory-mediated lung injury. Dermal fibroblast-derived exosomes (DF-Exos) have been demonstrated to alleviate inflammation and promote epithelial tissue repair; however, their role in lung injury remains to be elucidated. This study aimed to evaluate the effects of DF-Exos on BPD and explore their relationship with autophagy.
