AIMS: To describe the historical changes from antiquity until present in the presentation and treatment of male urinary incontinence. METHODS: A literature review of PubMed articles in English pertaining to male incontinence was performed. RESULTS: Male urinary incontinence was first mentioned in Egyptian manuscripts in 1500 B.C. In 1564, Ambroise Pare designed portable urinals for incontinent males. Wilhem Hildanus created the first condom catheter with pig bladder in the 1600s and was also credited with fashioning the first penile clamp...

In order to support the clinical application of human adipose-derived mesenchymal stem cell (haMSC) therapy for knee osteoarthritis (KOA), we examined the efficacy of cell persistence and biodistribution of haMSCs in animal models. We demonstrated a method to label the cell membrane of haMSCs with lipophilic fluorescent dye. Subsequently, intra-articular injection of the labeled cells in rats with surgically induced KOA was monitored dynamically by an in vivo imaging system. We employed the lipophilic carbocyanines DiD (DilC18 (5)), a far-red fluorescent Dil (dialkylcarbocyanines) analog, which utilized a red laser to avoid excitation of the natural green autofluorescence from surrounding tissues...

The possibility of using adipose tissue-derived stromal cells (ATSC) as alternatives to bone marrow-derived stromal cells (BMSC) for bone repair has garnered interest due to the accessibility, high cell yield, and rapid in vitro expansion of ATSC. For clinical relevance, their bone forming potential in comparison to BMSC must be proven. Distinct differences between ATSC and BMSC have been observed in vitro and comparison of osteogenic potential in vivo is not clear to date. The aim of the current study was to compare the osteogenesis of human xenofree-expanded ATSC and BMSC in vitro and in an ectopic nude mouse model of bone formation...

BACKGROUND AIMS: Retinal progenitor cells (RPCs) are a promising cell therapy treatment for retinal degenerative diseases. However, problems with limited proliferation ability and differentiation preference toward glia rather than neurons restrict the clinical application of these RPCs. The extracellular matrix (ECM) has been recognized to provide an appropriate microenvironment to support stem cell adhesion and direct cell behaviors, such as self-renewal and differentiation. METHODS: In this study, decellularized matrix of adipose-derived mesenchymal stromal cells (DMA) was manufactured using a chemical agent method (0...

Acute kidney injury (AKI) predisposes patients to an increased risk into progressive chronic kidney disease (CKD), however effective treatments are still elusive. This study aimed to investigate the therapeutic efficacy of human adipose-derived MSCs (hAD-MSCs) in the prevention of AKI-CKD transition, and illuminate the role of Sox9, a vital transcription factor in the development of kidney, in this process. C57BL/6 mice were subjected to unilateral renal ischemia/reperfusion (I/R) with or without hAD-MSC treatment...

Adult stromal mesenchymal stem cells (MSCs) have been postulated as responsible for cell renewal in highly and continuously regenerative tissues such as the endometrium. MSCs have been identified in the endometrium of many species including humans, rodents, pets and some farm animals, but not in horses. The objective of this work was to isolate such cells from the endometrium of mares and to compare their main biological attributes with horse adipose-derived MSCs. Here we successfully isolated and characterized endometrial MSCs (eMSCs) from mares...

Research using animal models gives human trials hope for recovery in many fields of regenerative medicine, although they are sometimes poor predictors for human experiences. Our goal was to investigate whether rat chondrocytes, differentiated from adipose-derived stem cells, could be transplanted using a new, easily shaped, bioactive glass scaffold, and to show the immunohistochemical results. Intraperitoneal and retroperitoneal adipose tissue was extracted from 6 male Wistar albino type rats. The fatty tissue samples were fragmented and incubated...

OBJECTIVE: Cinnamaldehyde (CA) is a food compound that has previously been observed to be protective against obesity and hyperglycemia in mouse models. In this study, we aimed to elucidate the mechanisms behind this protective effect by assessing the cell-autonomous response of primary adipocytes to CA treatment. METHODS: Primary murine adipocytes were treated with CA and thermogenic and metabolic responses were assessed after both acute and chronic treatments. Human adipose stem cells were differentiated and treated with CA to assess whether the CA-mediated signaling is conserved in humans...

In living tissue, cells exist in three-dimensional (3D) microenvironments with intricate cell-cell interactions. To model these cellular environments, numerous techniques for generating cell spheroids have been proposed and improved. However, previously reported methods still have limitations in uniformity, reproducibility, scalability, through-put, etc. Here, we present a centrifugal microfluidic-based spheroid (CMS) formation method for generating both co-culture and mono-culture 3D spheroids in a highly controlled manner...

Age-related macular degeneration (AMD) is associated with the dysfunction and death of the retinal pigment epithelium (RPE). Recently, there has been increasing interest in stem cell-derived RPE cells for cell replacement therapies, such as those for AMD. The present study investigated whether RPE-conditioned medium (RPECM) could promote the differentiation of human adipose tissue-derived mesenchymal stromal cells (hADSCs) into RPE cells, and enhance the proliferation and migration of these cells. Reverse-transcription quantitative polymerase chain reaction analysis demonstrated that RPECM induced hADSCs to differentiate into cells expressing RPE markers, including retinoid isomerohydrolase (RPE65), cytokeratin (CK8) and Bestrophin, which were identified to be significantly upregulated by ~10-fold, 3...

Scar formation is an intractable medical problem that appears after skin wounds have healed. Recent research has shown that exosomes secreted by human adipose mesenchymal stem cells (ASC-Exos) can benefit wound healing. To further explore the therapeutic potential of ASC-Exos, we investigated their effects on mitigating scar formation, and the underlying mechanisms of these effects. We found that intravenous injection of ASC-Exos decreased the size of scars and increased the ratio of collagen III to collagen I in murine incisional wounds...

Background: In previous papers, we demonstrated that the treatment of human photoaged skin with stromal-vascular fraction-enriched fat or expanded adipose-derived stem cells showed a decrease of elastosis and the appearance of new oxytalan elastic fibers in dermis and an increase in the vascular network. The utilization of fat plus platelet-rich plasma (PRP) led to an increase in the vascular permeability and reactivity of the nervous component. Objectives: The purpose of this study was to analyze the histologic and ultrastructural changes of human skin after the injection of only PRP in the retroauricular area that was not exposed to sun and did not present the photoaging process, in comparison with our previous results...

Environment-mediated drug resistance (EMDR) serves an important role in tumor chemotherapy resistance. Adipose‑derived mesenchymal stem cells (ADSC) are an important component of the tumor microenvironment. However, the role of ADSC in EMDR remains unclear. Therefore, in order to clarify whether ADSCs contribute to the cisplatin‑mediated apoptosis in epithelial ovarian cancer (EOC), the present study isolated ADSCs from the omentum of women with benign disease and collected the ADSC culture medium as conditioned medium...

BACKGROUND: Stem cells from adipose tissue offer a novel therapy for patients with damaged tissue. Stromal vascular fraction (SVF) injected into patients may reduce inflammation, promote healing, and repair damaged/scarred tissue. SVF can be isolated from fat (adipose) tissue in an outpatient procedure. The SVF population includes mesenchymal stem cells (MSCs), pericytes, endothelial/progenitor cells, fibroblasts and growth factors where the adipocyte (fat cell) population has been removed...

Isolated chondral defects have a limited capacity to heal and predispose to the development of osteoarthritis. Current surgical management can be unpredictable in outcome. Improved understanding of the action of mesenchymal stem cells (MSCs) has seen renewed interest in their role in cartilage repair. A 26-year-old athlete presented with a post-traumatic, isolated patella chondral defect. The patient underwent an arthroscopy with removal of a chondral loose body. After failure to symptomatically improve 12 months following surgery, the patient received intra-articular autologous adipose-derived mesenchymal stem cell (ADMSC) therapy...

Muscle regeneration is performed by resident muscle stem cells called satellite cells (SC). However they are multipotent, being able to adopt adipogenic and osteogenic fate under the correct stimuli. Since SC behavior can be regulated by the extra-cellular matrix, we examined the robustness of the myogenic programme of SC on their native substrate-the surface of a myofiber. We show that the native substrate supports myogenic differentiation judged by the expression of members of the Myogenic Determination Factor (MRF) family...

Brown adipocytes dissipate energy as heat and hence have an important therapeutic capacity for obesity. Development of brown-like adipocytes (also called beige) is also another attractive target for obesity treatment. Here, we investigated the effect of farnesol, an isoprenoid, on adipogenesis in adipocytes and on the browning of white adipose tissue (WAT) as well as on the weight gain of high-fat diet (HFD)-induced obese mice. Farnesol inhibited adipogenesis and the related key regulators including peroxisome proliferator-activated receptor γ (PPARγ) and CCAAT/enhancer binding protein α through the up-regulation of AMP-activated protein kinase in 3T3-L1 murine adipocytes and human adipose tissue-derived mesenchymal stem cells (hAMSCs)...

A more accurate understanding of the molecular mechanisms and signaling pathways underpinning human mesenchymal stem cell (MSC) plasticity and differentiation properties is pivotal for accomplishing solid and diligent translation of MSC-based experimental therapeutics and clinical trials to broad clinical practice. In addition, this knowledge enables selection of MSC subpopulations with increased differentiation potential and/or use of exogenous factors to boost this potential. Here, we report that CD105 (ENG) is a predictive biomarker of osteogenic potential in two types of MSCs: stem cells from human exfoliated deciduous teeth (SHED) and human adipose-derived stem cells (hASC)...

Considering that spleen plays an important role in the occurrence and development of diabetes, we aimed to investigate the role of the spleen in the treatment of type 2 diabetes (T2D) with adipose tissue-derived stem cells (ADSCs). We established a T2D/splenectomy (SPX) rat model using high-fat diet/streptozotocin (STZ) administration with SPX, then assessed the therapeutic effects of ADSCs, and explored the possible mechanism. A single ADSCs infusion was found to ameliorate hyperglycemia and insulin resistance in diabetic rats, accompanied by a considerable number of ADSCs homing to the spleens in T2D rats...

In current study we aimed to coat the PLLA scaffold with zinc (Zn) silicate mineral nanoparticles. Then, using equine adipose-derived stem cells (ASCs) we intended to compare the osteogenic induction potency of Zn silicate mineral-coated PLLA scaffold with uncoated PLLA scaffold and tissue culture plastic (TCPS). Adipose tissues were collected from 3 horses, and isolation of ASCs was achieved by enzymatic digestion. PLLA scaffold was successfully prepared using a phase separation method and coated with Zn silicate mineral nanoparticles...
