Cell Signal 2021 May 7:110036. Epub 2021 May 7.

Departamento de Biología Celular y Molecular and Center for Aging and Regeneration (CARE-ChileUC), Facultad de Ciencias Biológicas, Pontificia Universidad Católica de Chile, 8331150 Santiago, Chile; Fundación Ciencia & Vida, 7780272 Santiago, Chile.

Platelet-derived growth factors (PDGFs) regulate embryonic development, tissue regeneration, and wound healing through their binding to PDGF receptors, PDGFRα and PDGFRβ. However, the role of PDGF signaling in regulating muscle development and regeneration remains elusive, and the cellular and molecular responses of myogenic cells are understudied. Here, we explore the PDGF-PDGFR gene expression changes and their involvement in skeletal muscle myogenesis and myogenic fate. Read More

Rational selection of bioactive principles for wound healing applications: Growth factors and antioxidants.

Int Wound J 2021 May 5. Epub 2021 May 5.

Tecnologico de Monterrey, Escuela de Ingeniería y Ciencias, Monterrey, Nuevo León, Mexico.

Wound healing is a complex process of communication between growth factors, reactive species of oxygen, cells, signalling pathways, and cytokines in the extracellular matrix, in which growth factors are the key regulators. In humans, the main regulators of the cellular responses in wound healing are five growth factors, namely EGF, bFGF, VEGF, and TGF-β1. On the other hand, antioxidants such as astaxanthin, beta-carotene, epigallocatechin gallate, delphinidin, and curcumin have been demonstrated to stimulate cell proliferation, migration and angiogenesis, and control inflammation, to suggest a practical approach to design new strategies to treat non-healing cutaneous conditions.

miR-506-3p regulates TGF- 1 and affects dermal fibroblast proliferation, migration and collagen formation after thermal injury.

Tissue Cell 2021 Apr 21;72:101548. Epub 2021 Apr 21.

Department of Dermatology, The First Affiliated Hospital of Hunan University of Chinese Medicine, Changsha, 410007, China.

Dermal fibroblasts are a promising candidate for cellular-based therapies for thermal wound healing because of their capacity of producing extracellular matrix (ECM), promoting wound contraction and the synthesis of type I collagen, and secreting growth factors. miRNAs (MicroRNAs) might mediate the role of TGF-β1(Transforming Growth Factor-beta 1), one of the major profibrotic cytokines, in improving thermal injury repair.

Int J Mol Sci 2021 Apr 14;22(8). Epub 2021 Apr 14.

Department of Periodontology, School of Dental Medicine, University of Bern, 3010 Bern, Switzerland.

The aim of the present study was to investigate the influence of a novel volume-stable collagen matrix (vCM) on early wound healing events including cellular migration and adhesion, protein adsorption and release, and the dynamics of the hemostatic system. For this purpose, we utilized transwell migration and crystal violet adhesion assays, ELISAs for quantification of adsorbed and released from the matrix growth factors, and qRT-PCR for quantification of gene expression in cells grown on the matrix. Our results demonstrated that primary human oral fibroblasts, periodontal ligament, and endothelial cells exhibited increased migration toward vCM compared to control cells that migrated in the absence of the matrix.

Vopr Kurortol Fizioter Lech Fiz Kult 2021 ;98(2):45-54

Skin and venereal clinic N4, St.-Petersburg, Russia.

The scope of physical methods for correcting the pathological skin scars is rapidly growing but the results of their use are often unsatisfactory. An inadequate approach to therapy without taking into account the assessment of their effectiveness leads to relapses, increased growth of scar tissue or the absence of a clinically significant effect which requires strict scientific evidence in the course of benign scientific studies.

Objective: Scientometric analysis of evidence-based studies on the use of therapeutic physical factors in the correction of post-acne scars. Read More

TGF beta -1, -2 and -3 in the modulation of fibrosis in the cornea and other organs.

Authors:
Steven E Wilson

Exp Eye Res 2021 Apr 22;207:108594. Epub 2021 Apr 22.

The Cole Eye Institute, The Cleveland Clinic, Cleveland, OH, USA. Electronic address:

The TGF beta-1, -2 and -3 isoforms are transcribed from different genes but bind to the same receptors and signal through the same canonical and non-canonical signal transduction pathways. There are numerous regulatory mechanisms controlling the action of each isoform that include the organ-specific cells producing latent TGF beta growth factors, multiple effectors that activate the isoforms, ECM-associated SLRPs and basement membrane components that modulate the activity and localization of the isoforms, other interactive cytokine-growth factor receptor systems, such as PDGF and CTGF, TGF beta receptor expression on target cells, including myofibroblast precursors, receptor binding competition, positive and negative signal transduction effectors, and transcription and translational regulatory mechanisms. While there has long been the view that TGF beta-1and TGF beta-2 are pro-fibrotic, while TGF beta-3 is anti-fibrotic, this review suggests that view is too simplistic, at least in adult tissues, since TGF beta-3 shares far more similarities in its modulation of fibrotic gene expression with TGF beta-1 and TGF beta-2, than it does differences, and often the differences are subtle.
