Platelet-derived mitochondria transfer facilitates wound-closure by modulating ROS levels in dermal fibroblasts.
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 in vitro 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.
期刊介绍：
Platelets is an international, peer-reviewed journal covering all aspects of platelet- and megakaryocyte-related research.
Platelets provides the opportunity for contributors and readers across scientific disciplines to engage with new information about blood platelets. The journal’s Methods section aims to improve standardization between laboratories and to help researchers replicate difficult methods.
Research areas include:
Platelet function
Biochemistry
Signal transduction
Pharmacology and therapeutics
Interaction with other cells in the blood vessel wall
The contribution of platelets and platelet-derived products to health and disease
The journal publishes original articles, fast-track articles, review articles, systematic reviews, methods papers, short communications, case reports, opinion articles, commentaries, gene of the issue, and letters to the editor.
Platelets operates a single-blind peer review policy. Authors can choose to publish gold open access in this journal.
