The elucidation of the molecular mechanisms underlying the differentiation and proliferation of human adipose tissue-derived stromal cells (hADSCs) represents a critical step in the development of hADSCs-based cellular therapies. To examine the role of the microRNA-103a-3p (miR-103a-3p) in hADSCs functions, miR-103a-3p mimics were transfected into hADSCs in order to overexpress miR-103a-3p. Ost...

BACKGROUND/AIMS Demonstrating the molecular mechanisms of human adipose tissue-derived mesenchymal stem cells (hADSCs) differentiation and proliferation could develop hADSCs-based cell therapy. METHODS The microRNA-137 (miR-137) and cell division control protein 42 homolog (CDC42) levels were regulated by oligonucleotides transfection. The adipogenic differentiation was induced for 10 days in...

PURPOSE Erectile dysfunction (ED) remains a major complication from cavernous nerve injury during radical prostatectomy. Recently, stem cell treatment for ED has been widely reported. This study was conducted to investigate the availability, differentiation into functional cells, and potential of human muscle-derived stem cells (hMDSCs) and human adipose-derived stem cells (hADSCs) for ED treat...

Human adipose-tissue-derived stromal cells (hADSCs) are abundant in adipose tissue and can differentiate into multi-lineage cell types, including adipocytes, osteoblasts, and chondrocytes. In order to define the optimal harvest site of adipose tissue harvest site, we solated hADSCs from different subcutaneous sites (upper abdomen, lower abdomen, and thigh) and compared their proliferation and p...

BACKGROUND AND AIMS hADSCs transplantation in cirrhosis models improves liver function and reduces fibrosis. In addition, Ad-huPA gene therapy diminished fibrosis and increased hepatocyte regeneration. In this study, we evaluate the combination of these therapies in an advanced liver fibrosis experimental model. METHODS hADSCs were expanded and characterized before transplantation. Ad-huPA wa...

Platelet-rich plasma (PRP) has a pool of multiple growth factors efficient at inducing the proliferation and osteogenic differentiation of human adipose-derived stem cells (hADSCs). Bone morphogenetic protein (BMP)-2 is a strong stimulator for the osteogenic differentiation of hADSCs. The purpose of this study was to verify the effect of PRP-released growth factors and microsphere-encapsulated ...

Human adipose-derived stem cells (hADSCs) are easily isolated from fat tissue without ethical concerns, but differ in purity, pluripotency, differentiation ability, and stem cell marker expression, depending on the isolation method. We isolated hADSCs from a primary fat tissue solution using: (1) conventional culture, (2) a membrane filtration method, (3) a membrane migration method where the p...

NEL-like molecule 1 (NELL1) is a potent osteogenic factor associated with craniosynostosis. Adenoviruses, the most commonly used viral vectors for gene therapy, have several disadvantages that may restrict osteogenesis. Previous studies have shown that lentiviruses can serve as ideal vectors for gene therapy for bone regeneration. In this study, two lentiviral vectors (LvNELL1 and LvBMP2) that ...

Glioblastoma multiforme (GBM) is one of the most intractable of human cancers, principally because of the highly infiltrative nature of these neoplasms. Tracking and eradicating infiltrating GBM cells and tumor microsatellites is of utmost importance for the treatment of this devastating disease, yet effective strategies remain elusive. Here we report polymeric nanoparticle-engineered human adi...

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 mesen...
