Chemokines as Therapeutic Targets in Cardiovascular Disease.

Arterioscler Thromb Vasc Biol 2019 Feb 14:ATVBAHA118312037. Epub 2019 Feb 14.

Institute for Cardiovascular Prevention (IPEK), LMU Munich, Germany (C.W., R.R.K.).

With the incidence and impact of atherosclerotic cardiovascular disease and its clinical manifestations still rising, therapeutic options that target the causal mechanisms of this disorder are highly desired. Since the CANTOS trial has demonstrated that lowering inflammation can be beneficial, focusing on mechanisms underlying inflammation, for example, leukocyte recruitment, is feasible. Being key orchestrators of leukocyte trafficking, chemokines have not lost their attractiveness as therapeutic targets, despite the difficult road to drug approval thus far. Read More

Novel Hemicraniectomy Technique for Malignant Middle Cerebral Artery Infarction: Technical Note.

Oper Neurosurg (Hagerstown) 2019 Jan 11. Epub 2019 Jan 11.

Department of Neurosurgery, Baylor Scott & White Health, Scott and White Medical Center, Temple, Texas.

Background And Importance: Decompressive hemicraniectomy (DH) is the mainstay of treatment for malignant middle cerebral artery infarction (MMI). Although this operation significantly reduces mortality and improves functional outcomes, the conventional technique involves a reverse question mark incision starting anterior to the tragus that can injure the scalp's major blood supply, the superficial temporal artery (STA), which increases the risk of postoperative complications.

Clinical Presentation: We developed a modified DH technique to reduce surgical morbidity associated with injury to the STA, accommodate a large bone window for effective decompression, and improve operative speed. 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.

Hypoxia-elicited mesenchymal stem cell-derived exosomes facilitates cardiac repair through miR-125b-mediated prevention of cell death in myocardial infarction.

Theranostics 2018 29;8(22):6163-6177. Epub 2018 Nov 29.

Department of Geriatric Medicine, Xiangya Hospital, Central South University, Changsha, China 410008.

Exosomes (Exo) secreted from hypoxia-conditioned bone marrow mesenchymal stem cells (BM-MSCs) were found to be protective for ischemic disease. However, the role of exosomal miRNA in the protective effect of hypoxia-conditioned BM-MSCs-derived Exo (Hypo-Exo) remains largely uncharacterized and the poor specificity of tissue targeting of Exo limits their clinical applications. Therefore, the objective of this study was to examine the effect of miRNA in Hypo-Exo on the repair of ischemic myocardium and its underlying mechanisms. Read More

Cerebral fat embolism syndrome in sickle cell disease without evidence of shunt.

eNeurologicalSci 2019 Mar 22;14:19-20. Epub 2018 Nov 22.

Pennsylvania Hospital, 800 Spruce Street, Philadelphia, PA 19107, USA.

Fat embolism syndrome (FES) is a known complication of sickle cell disease (SCD) that occurs secondary to vaso-occlusive crises, bone marrow infarction, and the subsequent release of fat globules into the venous circulation. Although neurologic involvement is common, the pathophysiology of cerebral fat emboli remains controversial. While fat microemboli can enter the arterial circulation through right-to-left shunts, the systemic release of free fatty acids may also cause indirect endothelial damage and disruption of the blood-brain-barrier.

Anti-depressive effect of Shuangxinfang on rats with acute myocardial infarction: Promoting bone marrow mesenchymal stem cells mobilization and alleviating inflammatory response.

Biomed Pharmacother 2018 Dec 12;111:19-30. Epub 2018 Dec 12.

The Third Affiliate Hospital of Beijing University of Chinese Medicine, Beijing 100029, China. Electronic address:

Bone marrow mesenchymal stem cells (BM-MSCs) are recruited to injured site for cardiac self-repairing in acute myocardial infarction (AMI), but the spontaneous mobilization of BM-MSCs is insufficient for self-repairing. Inflammation initiated by necrosis cardiomyocytes induced cardiac remodeling and depression. Given the anti-inflammatory effects of BM-MSCs and the inextricably relationship among inflammation, ventricular remodeling and depression following AMI, methods focused on enhancing BM-MSCs mobilization are promising.

Mineralocorticoid receptor deficiency improves the therapeutic effects of mesenchymal stem cells for myocardial infarction via enhanced cell survival.

J Cell Mol Med 2019 Feb 13;23(2):1246-1256. Epub 2018 Dec 13.

Shanghai Institute of Cardiovascular Disease, Zhongshan Hospital, Fudan University, Shanghai, People's Republic of China.

The poor survival of stem cells seriously limits their therapeutic efficacy for myocardial infarction (MI). Mineralocorticoid receptor (MR) activation plays an important role in the pathogenesis of multiple cardiovascular diseases. Here, we examined whether MR silencing in bone marrow derived mesenchymal stem cells (MSCs) could improve MSCs' survival and enhance their cardioprotective effects in MI. Read More

Vasculature Remodeling in a Rat Model of Cerebral Ischemia. The Fate of the BrdU-Labeled Cells Prior to Stroke.

Front Neurol 2018 27;9:1014. Epub 2018 Nov 27.

Center of Clinical and Experimental Medicine, University of Medicine and Pharmacy of Craiova, Craiova, Romania.

Despite the clinical significance of post-stroke angiogenesis, a detailed phenotypic analysis of pre-stroke vascular remodeling and post-stroke angiogenesis had not yet been done in a model of focal ischemia. In this study, using BrdU-labeling of proliferating cells and immunofluorescence of pre- and post-stroke rats, we found that, (i) BrdU administered before stroke was incorporated preferentially into the nuclei of endothelial cells lining the lumen of existing blood vessels and newly born neurons in the dentate gyrus but not in the subventricular zone or proliferating microglia, (ii) BrdU injection prior to stroke led to the patchy distribution of the newly incorporated endothelial cells into existing blood vessels of the adult rat brain, (iii) BrdU injection prior to stroke specifically labeled neuronal precursors cells in a region of soft tissue beyond the inhibitory scar, which seems to be permissive to regenerative events, (iv) BrdU injection after stroke led to labeling of endothelial cells crossing or detaching from the disintegrating blood vessels and their incorporation into new blood vessels in the stroke region, scar tissue and the region beyond, (v) BrdU injection after stroke led to specific incorporation of BrdU-positive nuclei into the "pinwheel" architecture of the ventricular epithelium, (vi) blood vessels in remote areas relative to the infarct core and in the contralateral non-lesioned cortex, showed co-labeled BrdU/RECA endothelial cells shortly after the BrdU injection, which strongly suggests a bone marrow origin of the endothelial cells. In the damaged cortex, a BrdU/prolyl 4-hydroxylase beta double labeling in the close proximity to collagen IV-labeled basement membrane, suggests that, in addition to bone marrow derived endothelial cells, the disintegrating vascular wall itself could also be a source of proliferating endothelial cells, (vii) By day 28 after stroke, new blood vessels were observed in the perilesional area and the scar tissue region, which is generally considered to be resistant to regenerative events.

Triggering receptor expressed on myeloid cells-2 expression in the brain is required for maximal phagocytic activity and improved neurological outcomes following experimental stroke.

J Cereb Blood Flow Metab 2018 Dec 7:271678X18817282. Epub 2018 Dec 7.

1 Department of Neurology, University of California, San Francisco and the San Francisco Veterans Affairs Medical Center, San Francisco, CA, USA.

Triggering receptor expressed on myeloid cells-2 (TREM2) is an innate immune receptor that promotes phagocytosis by myeloid cells such as microglia and macrophages. We previously showed that TREM2 deficiency worsened outcomes from experimental stroke and impeded phagocytosis. However, myeloid cells participating in stroke pathology include both brain resident microglia and circulating macrophages. Read More

Infusion of third-party mesenchymal stromal cells after kidney transplantation: a phase I-II, open-label, clinical study.

Kidney Int 2018 Dec 6. Epub 2018 Dec 6.

Laboratory of Cell and Gene Therapy (LTCG), CHU of Liège, University of Liège (CHU ULiège), Liège, Belgium; GIGA, I3-Hematology, University of Liège (ULiège), Liège, Belgium; Division of Hematology, CHU of Liège, University of Liège (CHU ULiège), Liège, Belgium.

Mesenchymal stromal cells (MSCs) exhibit anti-inflammatory and immune-regulatory properties, and preclinical studies suggest a potential benefit in solid organ transplantation. We report on the 1-year follow-up of an open-label phase I-II trial of a single infusion of third-party MSC post-kidney transplantation, in addition to standard immunosuppression. Ten kidney transplant recipients from deceased donors received third-party bone marrow MSCs (∼2 × 10/kg) on day 3 ± 2 post-transplant and were compared to 10 concurrent controls. Read More

PECAM/eGFP transgenic mice for monitoring of angiogenesis in health and disease.

Sci Rep 2018 Dec 4;8(1):17582. Epub 2018 Dec 4.

Institute of Physiology I, Life&Brain Center, Medical Faculty, University of Bonn, Bonn, Germany.

For the monitoring of vascular growth as well as adaptive or therapeutic (re)vascularization endothelial-specific reporter mouse models are valuable tools. However, currently available mouse models have limitations, because not all endothelial cells express the reporter in all developmental stages. We have generated PECAM/eGFP embryonic stem (ES) cell and mouse lines where the reporter gene labels PECAM endothelial cells and vessels with high specificity. Read More

Muse Cells Are Endogenous Reparative Stem Cells.

Adv Exp Med Biol 2018 ;1103:43-68

Department of Stem Cell Biology and Histology, Tohoku University Graduate School of Medicine, Sendai, Japan.

The dynamics and actions of Muse cells at a time of physical crisis are unique and highly remarkable compared with other stem cell types. When the living body is in a steady state, low levels of Muse cells are mobilized to the peripheral blood, possibly from the bone marrow, and supplied to the connective tissue of nearly every organ. Under conditions of serious tissue damage, such as acute myocardial infarction and stroke, Muse cells are highly mobilized to the peripheral blood, drastically increasing their numbers in the peripheral blood within 24 h after the onset of tissue injury.
