BACKGROUND: Adipose tissue is an abundant source of mesenchymal stem cells, called adipose-derived stem cells, which have anti-inflammatory and trophic effects to enhance overall tissue repair. OBJECTIVE: To determine the healing effects of autologous adipose tissue graft on hypertensive leg ulcers. METHODS: Prospective pilot study in 1 French dermatology department. Ten patients with a hypertensive leg ulcer were enrolled from April 2013 to June 2015...

BACKGROUND: The intra-articular injection of mesenchymal stem cells (MSCs) into the knee has shown a potential for the treatment of generalized cartilage loss in osteoarthritis (OA). However, there have been few midterm reports with clinical and structural outcomes. PURPOSE: To assess the midterm safety and efficacy of an intra-articular injection of autologous adipose tissue-derived (AD) MSCs for knee OA at 2-year follow-up. STUDY DESIGN: Cohort study; Level of evidence, 3...

Pain associated to mechanical and chemical irritation of the eye surface is mediated by trigeminal ganglia mechano- and polymodal nociceptor neurons while cold thermoreceptors detect wetness and reflexly maintain basal tear production and blinking rate. These neurons project into two regions of the trigeminal brain stem nuclear complex: ViVc, activated by changes in the moisture of the ocular surface and VcC1, mediating sensory-discriminative aspects of ocular pain and reflex blinking. ViVc ocular neurons project to brain regions that control lacrimation and spontaneous blinking and to the sensory thalamus...

Degeneration of the intervertebral discs is a progressive cascade of cellular, compositional and structural changes that is frequently associated with low back pain. As the first signs of disc degeneration typically arise in the disc's central nucleus pulposus (NP), augmentation of the NP via hydrogel injection represents a promising strategy to treat early to mid-stage degeneration. The purpose of this study was to establish the translational feasibility of a triple interpenetrating network hydrogel composed of dextran, chitosan, and teleostean (DCT) for augmentation of the degenerative NP in a preclinical goat model...

Mast cells (MCs) are physiologically activated by binding of stem cell factor (SCF) to the extracellular domains of the Kit receptor. This binding increases the proliferation and prolongs the survival of normal mature MCs, as well as intensifies the release of mediators. In mastocytosis, somatic mutations of the coding Kit gene cause autocrine dysregulation and lead to constitutive KIT activation even in the absence of its ligand SCF. Clinical symptoms are caused by MC-mediator release and/or infiltration of MCs into tissues...

Varicella Zoster Virus (VZV) is a well-known virus that belongs to the Herpesviridae family which induces a self-limited disease except in specific cases in particular among stem cell transplant patients. This virus is not known however to trigger atypical Hemolytic Uremic Syndrome (aHUS). Here we report the case of a six-year-old boy who was hospitalized with fever and abdominal pains associated to pruritic and vesicular rash, thrombocytopenia and acute renal failure. He was diagnosed with aHUS precipitated by varicella virus...

Paroxysmal nocturnal haemoglobinuria is a non-malignant stem cell disorder due to acquired somatic mutations in cell surface anchored proteins CD55 and CD59. Both have a compliment inhibitory role and their deficiency leads to intravascular haemolysis. This paper reports a challenging case of a 25 years old male who presented with generalized weakness, exertional dyspnoea and episodic early morning haematuria. Recently, he started developing progressive abdominal distention and dull generalized abdominal pain...

A neck scar contracture can severely and negatively affect the function of mastication, phonic, or breathing and result in neck pain and issues with esthetics. The best way is of course to avoid such contracture by means of non-surgical treatment such as use of a growth factor. The basic fibroblastic growth factor is clinically well proven in decreasing scar formation and improving healing. There are numerous reconstructive methods for neck contracture, especially when the lesions are relatively limited in part of the neck...

Buerger's disease is a rare and severe disease affecting the blood vessels of the limbs. Adipose tissue-derived mesenchymal stem cells (ADSCs) have the potential to cure Buerger's disease when developed as a stem cell drug. In the present study, we conducted a prospective, nonrandomized, no placebo-controlled, phase I/II clinical trial with a 2-year follow-up questionnaire survey. A total of 17 patients were intramuscularly administered autologous ADSCs at a dose of 5 million cells/kg. The incidence of adverse events (AEs), adverse drug reaction (ADR), and serious adverse events (SAEs) was monitored...

Five shoulders in four patients affected by advanced osteonecrosis of the humeral head were treated with autologous concentrated bone marrow grafting. Bone marrow sample was aspirated from the iliac crests, concentrated by a centrifugation technique, and injected into the necrotic site. The shoulders were evaluated radiologically with X-ray scoring and clinically with measurement of range of motion and pain score (visual analogue scale, VAS). The mean follow-up period was 49.4 (range, 24-73) months. The concentration ratio of nucleated cells was calculated and the number of transplanted mesenchymal stem cells (MSC) was estimated by a colony-forming assay...

BACKGROUND: Autologous adipose-derived stromal vascular fraction (SVF), which is rich in mesenchymal stromal cells, has been reported to be effective for the treatment of trigeminal neuropathic pain and chronic migraine and tension-type headaches. It is possible that stem cell activity targets neurogenic inflammation, which is a well-documented aspect of migraine pathogenesis. METHODS: Adult patients with severe migraine-related disability as measured by the Migraine Disability Assessment (MIDAS) score who failed botulinum toxin injections and at least 3 prophylactic drugs were included in this study...

Background Gelatinous corneal dystrophy is a very rare disease in Europe and North America. Patients suffer from pain, photophobia and loss of vision, usually before the age of 20. Transplantation of limbal stem cells was proposed due to the high rate of recurrence after conventional penetrating keratoplasty. We present the results of penetrating limbokeratoplasty, a combined transplantation of cornea and limbal stem cells, in patients with gelatinous corneal dystrophy. Methods We present a series of 7 consecutive eyes with gelatinous corneal dystrophy, which were treated with penetrating limbokeratoplasty-4 eyes of 3 patients had already undergone multiple conventional corneal transplantations...

Mucositis is a complex, dose-limiting toxicity of chemotherapy or radiotherapy that leads to painful mouth ulcers, difficulty eating or swallowing, gastrointestinal distress, and reduced quality of life for patients with cancer. Mucositis is most common for those undergoing high-dose chemotherapy and hematopoietic stem cell transplantation and for those being treated for malignancies of the head and neck. Treatment and management of mucositis remain challenging. It is expected that multiple genes are involved in the formation, severity, and persistence of mucositis...

Chronic graft-versus-host disease (cGVHD) is a debilitating complication arising in around half of all patients treated with an allogeneic hematopoietic stem cell transplantation. Even though treatment of severe cGVHD has improved during recent years, it remains one of the main causes of morbidity and mortality in affected patients. Biomarkers in blood that could aid in the diagnosis and classification of cGVHD severity are needed for the development of novel treatment strategies that can alleviate symptoms and reduce the need for painful and sometimes complicated tissue biopsies...

Oral mucositis (OM) is a debilitating and serious side effect in patients undergoing hematopoietic stem cell transplantation (HSCT) and chemotherapy (CT). Laser therapy is becoming a promising treatment option in these patients, avoiding the necessity of enteral/parenteral nutrition. The aim of this study was to evaluate the efficacy of laser therapy in patients affected by oral mucositis induced by chemotherapy and HSCT. Sixteen onco-hematological pediatric patients receiving chemotherapy and hematopoietic stem cell transplantation, affected by oral mucositis, were enrolled in this study...

Stem cells have been used in novel therapeutic strategies for spinal cord injury (SCI), but the effect of stem cell transplantation on neuropathic pain after SCI is unclear. The current meta-analysis evaluates the effects of stem cell transplantation on neuropathic pain after SCI.
