Biological modulation of corneal epithelial wound healing.

Arq Bras Oftalmol 2019 Jan-Feb;82(1):78-84

Centro Avançado de Superfície Ocular, Departamento de Oftalmologia e Ciências Visuais, Universidade Federal de São Paulo, São Paulo, SP, Brasil.

The transparency and maintenance of corneal epithelial integrity are essential for its optical properties and, to preserve these characteristics, the epithelium undergoes continuous renewal. This renewal depends on the control of cell proliferation and differentiation mediated by mitogenic factors responsible for increasing mitoses and stimulating cellular migration. Cell-cell communication plays a pivotal role in epithelial healing process, and several cytokines and growth factors are involved in this process. Read More

Conditioned media serived from mesenchymal stem cell cultures: The next generation for regenerative medicine.

J Tissue Eng Regen Med 2019 Jan 15. Epub 2019 Jan 15.

Department of Restorative Dentistry, Faculty of Dentistry, University of Malaya, Kuala Lumpur, Malaysia.

Recent studies suggest that the main driving force behind the therapeutic activity observed in mesenchymal stem cells (MSCs) are the paracrine factors secreted by these cells. These biomolecules also trigger anti-apoptotic events to prevent further degeneration of the diseased organ through paracrine signalling mechanisms. In comparison to the normal physiological conditions, an increased paracrine gradient is observed within the peripheral system of diseased organs which enhances the migration of tissue specific MSCs towards the site of infection or injury to promote healing.

Molecular mechanisms in the pathogenesis of N-nitrosodimethylamine induced hepatic fibrosis.

Cell Death Dis 2019 Jan 8;10(1):18. Epub 2019 Jan 8.

Department of Hepatology, Kanazawa Medical University, Uchinada, Ishikawa, 920-0293, Japan.

Hepatic fibrosis is marked by excessive synthesis and deposition of connective tissue proteins, especially interstitial collagens in the extracellular matrix of the liver. It is a result of an abnormal wound healing in response to chronic liver injury from various causes such as ethanol, viruses, toxins, drugs, or cholestasis. The chronic stimuli involved in the initiation of fibrosis leads to oxidative stress and generation of reactive oxygen species that serve as mediators of molecular events involved in the pathogenesis of hepatic fibrosis.

Extracellular Vesicles Released by Human Induced-Pluripotent Stem Cell-Derived Cardiomyocytes Promote Angiogenesis.

Front Physiol 2018 14;9:1794. Epub 2018 Dec 14.

Dorothy M. Davis Heart & Lung Research Institute, The Ohio State University Wexner Medical Center, Columbus, OH, United States.

Although cell survival post-transplantation is very low, emerging evidence using stem cell therapy for myocardial repair points toward a primary role of paracrine signaling mechanisms as the basis for improved cardiac function, decreased fibrosis, and increased angiogenesis. Recent studies have demonstrated that extracellular vesicles (EVs) such as exosomes secreted by stem cells stimulate angiogenesis, provide cytoprotection, and modulate apoptosis. However, the angiogenic potential of EVs secreted from human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CM), a terminally differentiated cell type, has not been elucidated yet.

Fibrin nanoparticles coupled with keratinocyte growth factor enhance dermal wound healing rate.

ACS Appl Mater Interfaces 2019 Jan 3. Epub 2019 Jan 3.

Expediting the wound healing process is critical for patients chronically ill from non-healing wounds and diseases such as hemophilia or diabetes or who have suffered trauma including easily infected open wounds. FDA-approved external tissue sealants include the topical application of fibrin gels, which can be 500 times denser than natural fibrin clots. With lower clot porosity and higher polymerization rates than physiologically formed fibrin clots, the commercial gels quickly stop blood loss, but impede the later clot degradation kinetics and thus retard tissue-healing rates.

Pericyte Secretome.

Adv Exp Med Biol 2018 ;1109:139-163

Translational Neurology Group, Department of Clinical Sciences and Wallenberg Center for Molecular Medicine, Department of Neurology, Lund University, Lund, Sweden.

The role of pericytes seems to extend beyond their known function in angiogenesis, fibrosis and wound healing, blood-brain barrier maintenance, and blood flow regulation. More and more data are currently accumulating indicating that pericytes, uniquely positioned at the interface between blood and parenchyma, secrete a large plethora of different molecules in response to microenvironmental changes. Their secretome is tissue-specific and stimulus-specific and includes pro- and anti-inflammatory factors, growth factors, and extracellular matrix as well as microvesicles suggesting the important role of pericytes in the regulation of immune response and immune evasion of tumors.

Mesenchymal stromal cells derived exosomes as tools for chronic wound healing therapy.

Rom J Morphol Embryol 2018 ;59(3):655-662

Laboratory of Mesenchymal Stromal Progenitor Cells Therapy, Department of Regenerative Medicine, "Nicolae Simionescu" Institute of Cellular Biology and Pathology, Bucharest, Romania;

In modern society, the healing of chronic wounds is still a major cause of discomfort for the patients and a financial burden for the care system. Current approaches use either organic tissue-engineered skin substitutes or stem cells based therapy. It has been shown that mesenchymal stem cells (MSCs) are able to improve the wound healing process by secreting factors with anti-inflammatory, anti-fibrotic and pro-angiogenic activities either as soluble molecules (growth factors, cytokines) or encapsulated within membrane vesicles (microparticles, exosomes).

Characterization of thoracal fat depots - expression of adipokines and remodeling factors and impact of adipocyte conditioned media in fibroblast scratch assays.

Clin Hemorheol Microcirc 2018 ;70(3):267-280

Department of Cardiac Surgery, Faculty of Medicine Carl Gustav Carus, Technische Universität Dresden, Herzzentrum Dresden, Germany.

Adipose tissue is not only a connective tissue but also an endocrine organ secreting adipokines like Leptin and Adiponectin, lipokines such as palmitoileic acid and extracellular vesicles. These factors and the expression of matrix remodeling enzymes impact surrounding tissues via paracrine effects. The expression of selected secretion factors and the effect of adipocyte conditioned media from four thoracal adipose tissue origins - subcutaneous, perivascular, pericardial and epicardial adipose tissues - in a fibroblast proliferation/wound healing scratch assay model were investigated.

Modified VEGF-A mRNA induces sustained multifaceted microvascular response and accelerates diabetic wound healing.

Sci Rep 2018 Nov 30;8(1):17509. Epub 2018 Nov 30.

Department of Biomedical Engineering, University of Virginia, Charlottesville, VA, 22908, United States.

Capable of mediating efficient transfection and protein production without eliciting innate immune responses, chemically modified mRNA holds great potential to produce paracrine factors at a physiologically beneficial level, in a spatiotemporally controlled manner, and with low toxicity. Although highly promising in cardiovascular medicine and wound healing, effects of this emerging therapeutic on the microvasculature and its bioactivity in disease settings remain poorly understood. Here, we longitudinally and comprehensively characterize microvascular responses to AZD8601, a modified mRNA encoding vascular endothelial growth factor A (VEGF-A), in vivo. Read More

The Focus and Target: Angiogenesis in Refractory Wound Healing.

Int J Low Extrem Wounds 2018 Dec 3;17(4):301-303. Epub 2018 Dec 3.

1 College of Life Sciences, PLA General Hospital, PLA Medical College, Beijing, People's Republic of China.

In recent years, wound repair, especially chronic and refractory wounds, is still a growing worldwide health problem that concerns the physical and mental health of patients and the productivity of society as a whole. In many developed countries and developing countries, such as China, rapid economic growth, negative lifestyle changes (such as increased dietary fat intake and reduced physical activity), and increasingly serious aging problems have led to more and more refractory wounds caused by chronic diseases, such as diabetes and microvascular diseases. There is a clear and orderly stage in the process of wound healing, and the malfunction of any step will lead to poor healing effect. Read More

R-Ras regulates vascular permeability, but not overall healing in skin wounds.

Exp Dermatol 2018 Nov 29. Epub 2018 Nov 29.

Faculty of Medicine and Life Sciences, University of Tampere, Tampere, Finland.

Wounds close by keratinocytes migrating from the edge of the wound and re-epithelializing the epidermis. It has been proposed that the major stimuli for wound closure are blood-derived growth factors, chemokines and cytokines. The small GTPase R-Ras, a known integrin activator, also regulates vascular permeability during angiogenesis, and blood vessels lacking R-Ras leak plasma proteins constantly. Read More
