Objective: Human amniotic membranes have been shown to be effective for healing diabetic foot ulcers clinically and to regulate stem cell activity in vitro and in vivo; however, diabetic stem cells may be impaired as a sequela of the disease. In this study, dehydrated human amnion/chorion membrane (dHACM) allografts (EpiFix®; MiMedx Group) were evaluated for their ability to regulate diabetic s...

In recent years, Platelet Rich Plasma (PRP) and Adipose-Derived Stem Cells (ADSCs) have been used separately for many clinical applications, especially skin rejuvenation. A combined injection of PRP and ADSCs could therefore be used to treat skin wrinkles. However, there are controversies and reports with conflicting results regarding the efficacy of this treatment. The authors aimed to determi...

Mesenchymal stem cell (MSC)-based cell therapy is a promising avenue for osteoarthritis (OA) treatment. In the present study, we evaluated the efficacy of intra-articular injections of culture-expanded allogenic adipose tissue-derived stem cells (ADSCs) for the treatment of anterior cruciate ligament transection (ACLT) induced rat OA model. The paracrine effects of major histocompatibility comp...

RATIONALE Transplantation of stem cells into damaged hearts has had modest success as a treatment for ischemic heart disease. One of the limitations is the poor stem cell survival in the diseased microenvironment. Prolyl hydroxylase domain protein 2 (PHD2) is a cellular oxygen sensor that regulates 2 key transcription factors involved in cell survival and inflammation: hypoxia-inducible factor ...

Previous studies have shown the beneficial effects of adipose-derived stem cells (ADSCs) transplantation in stroke. However, the molecular mechanism by which transplanted ADSCs promote nerve healing is not yet elucidated. In order to make clear the molecular mechanism for the neuroprotective effects of ADSCs and investigate roles of the BDNF-TrkB signaling in neuroprotection of ADSCs, we, there...

BACKGROUND/PURPOSE Previous studies suggested that mesenchymal stem cells may ameliorate fibrogenesis through the inhibition of hepatic stellate cells (HSCs) activation. This study aimed to investigate whether adipose derived mesenchymal stem cells (ADSCs) could modulate the activation of HSCs and contribute to the recovery of liver fibrogenesis. METHODS ADSCs and HSCs were isolated from Spra...

We have recently characterized a stem cell population isolated from the rodent amniotic membrane termed amnion-derived stem cells (ADSCs). In vitro ADSCs differentiate into cell types representing all three embryonic layers, including neural cells. In this study we evaluated the neuroectodermal potential of ADSCs in vivo after in utero transplantation into the developing rat brain. A clonal lin...

Osteoarthritis (OA) is one of the most common debilitating disorders among the elderly population. At present, there is no definite cure for the underlying causes of OA. However, adipose tissue-derived stem cells (ADSCs) in the form of stromal vascular fraction (SVF) may offer an alternative at this time. ADSCs are one type of mesenchymal stem cells that have been utilized and have demonstrated...

BACKGROUND Adipose-derived stem cells (ADSCs) are a population of pluripotent cells, which have characteristics similar to bone marrow-derived mesenchymal stem cells. Whereas ADSCs have potential applications for the repair and regeneration of various damaged tissues, few studies have dealt with the effect of ADSCs on fibroblasts, which play a key role in skin biology. OBJECTIVE In this study...

A robust method for inducing bone formation from adipose-derived stromal cells (ADSCs) has not been established. Moreover, the efficacy of strong osteogenic inducers including BMP-2 for ADSC-mediated bone engineering remains controversial. Meanwhile, the buccal fat pad (BFP), which is found in the oral cavity as an adipose-encapsulated mass, has been shown to have potential as a new accessible ...
