Inhibin-α, a member of the transforming growth factor (TGF-β) superfamily, has been involved in bone turnover during the menopausal transition via endocrine effects, and it was previously reported that inhibins may antagonize the function of BMPs. Certainly, one of the most important functions of BMPs is to induce osteogenic differentiation. BMP9 as one of the most potent BMPs to induce osteogenic differentiation has gotten more and more attentions. Nonetheless, the effects of inhibin-α on osteogenesis remain unknown...

Human hair dermal papilla (DP) cells are specialized mesenchymal cells that play a pivotal role in hair regeneration and hair cycle activation. The current study aimed to first develop three-dimensional (3D) DP spheroids (DPS) with or without a silk-gelatin (SG) microenvironment, which showed enhanced DP-specific gene expression, resulting in enhanced extracellular matrix (ECM) production compared with a monolayer culture. We tested the feasibility of using this DPS model for drug screening by using minoxidil, which is a standard drug for androgenic alopecia...

Bladder cancer (BC) is one of the most frequent urological malignancies, and its molecular mechanism still remains unclear. Recent studies have revealed that MicroRNA (miRNAs) acted as oncogenes or tumor suppressors in a variety of cancers. MiRNA-96 has been reported to play a significant role in the development and progression of many cancers. In the current study, we found that transforming growth factor (TGF)-β1 played a significant role in the progression that miR-96 conducted. And TGF-β1 could also regulate the expression of FOXQ1, which is the target gene of miR-96...

The Human Salivary Gland cell line (HSG), labelled as a submandibular ductal cell line, is commonly used as in vitro models to study radiation therapy, Sjögren's syndrome, pleomorphic adenoma, mucocele, epithelial-to-mesenchymal transition, and epigenetics. However, the American Type Culture Collection (ATCC) has recently released a list of cross-contaminated cell lines that included HSG. Despite this notice, some research labs still use HSG as a salivary cell model. Accordingly, this study examined the authenticity of HSG sampled from three different laboratories METHODS: DNA was extracted from HSG and additional salivary cell lines (NS-SV-AC, NS-SV-DC, A253, HSY), and submitted for cell line authentication with short tandem repeat (STR) analysis RESULTS: All HSG samples had STR profiles indicating > 80% match with HeLa in both the ATCC and Deutsche Sammlung von Mikroorganismen und Zellkulturen (DSMZ) databases...

Gingival tissue is reportedly a promising, easily accessible, abundant resource of mesenchymal stem cells (MSC) for use in various tissue engineering strategies. Human gingival MSC (HGMSCs) were successfully isolated from gingival tissue and characterized. To analyze in a two-dimensional form, HGMSCs were cultured with basal medium and induced with 25 µg/ml of Acalypha indica. Quantitative real-time polymerase chain reaction (qPCR) and western blot analysis showed the presence of keratinocyte-specific markers, including cytokeratin-5 and involucrin...

The aim of this study is to evaluate the ability of microRNA-183 (miR-183) to influence epithelial-mesenchymal transition (EMT) and cell proliferation, migration, invasion, and apoptosis in endometrial cancer (EC) by targeting cytoplasmic polyadenylation element binding protein 1(CPEB1). EC tissues with matched nonmalignant tissues were collected from 208 EC patients. Ishikawa and RL95-2 cells were selected for cell experiments in vitro and each kind of cells were grouped into blank, negative control (NC), miR-183 mimic, miR-183 inhibitor, CPEB1 overexpression, and miR-183 mimic + CPEB1 overexpression groups...

KEY POINTS: Chronic inflammation underlies many of the health decrements associated with obesity. Circulating progenitor cells can sense and respond to inflammatory stimuli, increasing the local inflammatory response within tissues. Here we show that 6 weeks of endurance exercise training significantly decreases inflammatory circulating progenitor cells in obese adults. These findings provide novel cellular mechanisms for the beneficial effects of exercise in obese adults. ABSTRACT: Circulating progenitor cells (CPCs) and subpopulations are normally found in the bone marrow, but can migrate to peripheral tissues to participate in local inflammation and/or remodelling...

PURPOSE: Dysregulation of miRNA profile has been associated with a broad spectrum of cellular processes underlying progression of various human malignancies. Increasing evidence suggests that specific microRNA clusters might be of clinical utility, especially in triple-negative breast carcinoma (TNBC), devoid of both predictive markers and potential therapeutic targets. Here we provide a comprehensive review of the existing data on microRNAs in TNBC, their molecular targets, a putative role in invasive progression with a particular emphasis on the epithelial-to-mesenchymal transition (EMT) and acquisition of stem-cell properties (CSC), regarded both as prerequisites for metastasis, and significance for therapy...

Cancer is a leading cause of death worldwide, and its incidence is rising with numbers expected to increase 70% in the next two decades. The fact that current mainline treatments for cancer patients are accompanied by debilitating side effects prompts a growing demand for new therapies that not only inhibit growth and proliferation of cancer cells, but also control invasion and metastasis. One class of targets gaining international attention is the aquaporins, a family of membrane-spanning water channels with diverse physiological functions and extensive tissue-specific distributions in humans...

The pathogenesis of Dupuytren's disease (DD) remains unclear although there is increasing evidence supporting the role of stem cells in this and other fibrotic conditions. This review examines the role of DD tissue-associated embryonic stem cells (ESCs) and mesenchymal stem cells (MSCs), and circulating fibrocytes and circulating MSCs, in the biology of DD. It is exciting to infer that dysfunction of an upstream ESC-like population within the affected tissue leads to the downstream development and proliferation of aberrant myofibroblasts through a putative MSC intermediate...

Large bone defects remain a tremendous clinical challenge. There is growing evidence in support of treatment strategies that direct defect repair through an endochondral route, involving a cartilage intermediate. While culture-expanded stem/progenitor cells are being evaluated for this purpose, these cells would compete with endogenous repair cells for limited oxygen and nutrients within ischaemic defects. Alternatively, it may be possible to employ extracellular vesicles (EVs) secreted by culture-expanded cells for overcoming key bottlenecks to endochondral repair, such as defect vascularization, chondrogenesis, and osseous remodelling...

Objectives: Allergic Asthma is an inflammatory disease of the lungs that is characterized by increased infiltration of leukocytes into the airways, limiting the respiratory function. Studies suggest that a defective general regulatory system against inflammation could be a significant factor in allergic asthma. It has been shown that Mesenchymal stem cells (MSCs) have a cellular immunosuppressive therapeutic potential for inflammatory disorders. We investigated whether administration of MSCs during allergen challenge would affect the underlying mechanisms in allergic airways inflammation...

Mesenchymal stem cells (MSCs) are considered as primary candidates for cell-based therapies due to their multiple effects in regenerative medicine. Pre-conditioning of MSCs under physiological conditions—such as hypoxia, three-dimensional environments, and dynamic cultivation—prior to transplantation proved to optimize their therapeutic efficiency. When cultivated as three-dimensional aggregates or spheroids, MSCs display increased angiogenic, anti-inflammatory, and immunomodulatory effects as well as improved stemness and survival rates after transplantation, and cultivation under dynamic conditions can increase their viability, proliferation, and paracrine effects, alike...

Cancer invasion and metastasis are driven by epithelial-to-mesenchymal transition (EMT), yet the exact mechanisms that account for EMT in clinical prostate cancer are not fully understood. Expression of N-cadherin is considered a hallmark of EMT in clinical prostate cancer. In this study, we determined the molecular mechanisms associated with N-cadherin expression in prostate cancer patients. We performed laser capture micro-dissection of matched N-cadherin-positive and -negative prostate cancer areas from patient samples (n=8) followed by RNA sequencing...
