Abstract
The importance of flow shear stress (SS) on the differentiation of endothelial progenitor cells (EPCs) has been demonstrated in various studies. Cholesterol retention and microRNA regulation have been also proposed as relevant factors involved in this process, though evidence regarding their regulatory roles in the differentiation of EPCs is currently lacking. In the present study on high shear stress (HSS)-induced differentiation of EPCs, we investigated the importance of ATP-binding cassette transporter 1 (ABCA1), an important regulator in cholesterol efflux, and miR-25-5p, a potential regulator of endothelial reconstruction. We first revealed an inverse correlation between miR-25-5p and ABCA1 expression levels in EPCs under HSS treatment; their direct interaction was subsequently validated by a dual-luciferase reporter assay. Further studies using flow cytometry and quantitative polymerase chain reaction demonstrated that both miR-25-5p overexpression and ABCA1 inhibition led to elevated levels of specific markers of endothelial cells, with concomitant downregulation of smooth muscle cell markers. Finally, knockdown of ABCA1 in EPCs significantly promoted tube formation, which confirmed our conjecture. Our current results suggest that miR-25-5p might regulate the differentiation of EPCs partially through targeting ABCA1, and such a mechanism might account for HSS-induced differentiation of EPCs.

The role of 5-HT 2B receptors in mitral valvulopathy: bone marrow mobilization of endothelial progenitors. Br J Pharmacol 2017; 174:4123-4139. [PMID: 28806488 DOI: 10.1111/bph.13981] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2017] [Revised: 07/03/2017] [Accepted: 08/03/2017] [Indexed: 12/20/2022] Open
Abstract
BACKGROUND AND PURPOSE Valvular heart disease (VHD) is highly prevalent in industrialized countries. Chronic use of anorexigens, amphetamine or ergot derivatives targeting the 5-HT system is associated with VHD. Here, we investigated the contribution of 5-HT receptors in a model of valve degeneration induced by nordexfenfluramine, the main metabolite of the anorexigens, dexfenfluramine and benfluorex. EXPERIMENTAL APPROACH Nordexfenfluramine was infused chronically (28 days) in mice ((WT and transgenic Htr2B -/- , Htr2A -/- , and Htr2B/2A -/- ) to induce mitral valve lesions. Bone marrow transplantation was also carried out. Haemodynamics were measured with echocardiography; tissues and cells were analysed by histology, immunocytochemistry, flow cytometry and RT -qPCR. Samples of human prolapsed mitral valves were also analysed. KEY RESULTS Chronic treatment of mice with nordexfenfluramine activated 5-HT2B receptors and increased valve thickness and cell density in a thick extracellular matrix, mimicking early steps of mitral valve remodelling. Lesions were prevented by 5-HT2A or 5-HT2B receptor antagonists and in transgenic Htr2B -/- or Htr2A/2B -/- mice. Surprisingly, valve lesions were mainly formed by numerous non-proliferative CD34+ endothelial progenitors. These progenitors originated from bone marrow (BM) as revealed by BM transplantation. The initial steps of mitral valve remodelling involved mobilization of BM-derived CD34+ CD31+ cells by 5-HT2B receptor stimulation. Analysis of human prolapsed mitral valves showing spontaneous degenerative lesions, demonstrated the presence of non-proliferating CD34+ /CD309+ /NOS3+ endothelial progenitors expressing 5-HT2B receptors. CONCLUSIONS AND IMPLICATIONS BM-derived endothelial progenitor cells make a crucial contribution to the remodelling of mitral valve tissue. Our data describe a new and important mechanism underlying human VHD.

Deriving vascular smooth muscle cells from mesenchymal stromal cells: Evolving differentiation strategies and current understanding of their mechanisms. Biomaterials 2017; 145:9-22. [PMID: 28843066 DOI: 10.1016/j.biomaterials.2017.08.028] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2017] [Revised: 08/07/2017] [Accepted: 08/14/2017] [Indexed: 12/11/2022]
Abstract
Vascular smooth muscle cells (VSMCs) play essential roles in regulating blood vessel form and function. Regeneration of functional vascular smooth muscle tissue to repair vascular diseases is an area of intense research in tissue engineering and regenerative medicine. For functional vascular smooth muscle tissue regeneration to become a practical therapy over the next decade, the field will need to have access to VSMC sources that are effective, robust and safe. While pluripotent stem cells hold good future promise to this end, more immediate translation is expected to come from approaches that generate functional VSMCs from adult sources of multipotent adipose-derived and bone marrow-derived mesenchymal stromal cells (ASCs and BMSCs). The research to this end is extensive and is dominated by studies relating to classical biochemical signalling molecules used to induce differentiation of ASCs and BMSCs. However, prolonged use of the biochemical induction factors is costly and can cause potential endotoxin contamination in the culture. Over recent years several non-traditional differentiation approaches have been devised to mimic defined aspects of the native micro-environment in which VSMCs reside to contribute to the differentiation of VSMC-like cells from ASCs and BMSCs. In this review, the promises and limitations of several non-traditional culture approaches (e.g., co-culture, biomechanical, and biomaterial stimuli) targeting VSMC differentiation are discussed. The extensive crosstalk between the underlying signalling cascades are delineated and put into a translational context. It is expected that this review will not only provide significant insight into VSMC differentiation strategies for vascular smooth muscle tissue engineering applications, but will also highlight the fundamental importance of engineering the cellular microenvironment on multiple scales (with consideration of different combinatorial pathways) in order to direct cell differentiation fate and obtain cells of a desired and stable phenotype. These strategies may ultimately be applied to different sources of stem cells in the future for a range of biomaterial and tissue engineering disciplines.

Mast Cell Serotonin Immunoregulatory Effects Impacting on Neuronal Function: Implications for Neurodegenerative and Psychiatric Disorders. Neurotox Res 2015; 28:147-53. [PMID: 26038194 DOI: 10.1007/s12640-015-9533-0] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2015] [Revised: 05/15/2015] [Accepted: 05/15/2015] [Indexed: 01/05/2023]
Abstract
Mast cells (MCs) are derived from hemopoietic precursor cells, undergo their maturation in peripheral tissues, and play a significant role in both the innate and adaptive immune response. Cross-linking of the FcεRI on MCs initiates activation of several cytoplasmic protein tyrosine kinases which rapidly lead to phosphorylation and recruitment of adaptor molecules. These effects trigger the release of preformed mediators stored in the cytoplasmic granules, including histamine, serotonin and tryptase, as well as newly synthesized mediators, such as cytokines/chemokines, prostaglandins, leukotrienes, and growth factors. Serotonin (5-HT) is a bioactive monoamine, which has seven specific cell surface membrane bound receptors which are coupled to G-proteins, plays an important role in the central and peripheral nervous system, and is one of the key mediators in signaling between nervous and immune systems. Serotonin is not stored in all MC types but is implicated in MC adhesion, chemotaxis, tumorigenesis, and tissue regeneration through smooth muscle differentiation of stromal cells. Recent evidence indicates that serotonin has immunoregulatory actions that may be important in neuropsychiatric conditions. Chemokines, RANTES/CCL5, MCP-1/CCL2, and related molecules, constitute the C-C class of chemokine supergene family, play a role in regulating T helper-cell cytokine production and MC trafficking, and are involved in histamine and serotonin generation and MC functions. Pro-inflammatory cytokines such as interleukin-1-β and tumor necrosis factor which mediate MC response, are capable of activating p38 MAPK, and might increase serotonin generation through p38 MAPK activation. Here, we review the relationship between MCs and serotonin and its role in inflammatory diseases and neuroimmune interactions.
