tem cell biology has made cell-based therapies promising. While the use of human embryonic stem cells is ethically controversial, adult stem cells attracts more and more attention from clinicians and scientists. Adult mesenchymal stem cells (MSC) are derived from various tissues, including bone marrow, subcutaneous adipose tissue, cruciate ligament, muscle, and synovium,1 which are potential do...

The identification of multipotent adipose-derived stromal cells (ASC) has raised hope that tissue regeneration approaches established with bone-marrow-derived stromal cells (BMSC) can be reproduced with a cell-type that is far more accessible in large quantities. Recent detailed comparisons, however, revealed subtle functional differences between ASC and BMSC, stressing the concept of a common ...

The most efficient method to expand limbal stem cells (LSCs) in vitro for clinical transplantation is to culture single LSCs directly on growth-arrested mouse fibroblast 3T3 cells. To reduce possible xenobiotic contamination from 3T3s, primary human adipose-derived stem cells (ASCs) were examined as feeder cells to support the expansion of LSCs in vitro. To optimize the ASC-supported culture, f...

arm grooves of star-fish have mesenchymal stem cells derived from adipose tissue cell. widespread studies have shown that stem cells derived from adipose-derived mesenchymal stem cell from bone marrow have many similarities in terms of the ability to differentiate into a variety of tissues. most of the animals live in warm and shallow waters and the waters of this feature is that it is low in d...

Human adipose tissue represents an abundant, practical and appealing source of donor tissue for autologous cell replacement. Recent findings have shown that stem cells within the stromalvascular fraction of adipose tissue display a multilineage developmental potential. Adipose tissue-derived stem cells can be differentiated towards adipogenic, osteogenic, chondrogenic,myogenic and neurogenic li...

BACKGROUND Adipose tissue-derived stem cells (ASCs) have been recently isolated from human subcutaneous adipose tissue. ASCs may be useful in regenerative medicine as an alternative to bone marrow-derived stem cells. Changes in the oxygen concentration influence physiological activities, such as stem cell proliferation. However, the effects of the oxygen concentration on ASCs remain unclear. In...

background cleft palate (cp) is a common congenital defect. it makes serious difficulties for cleft-affected children. the gold standard of care is autogenous bone grafting which may cause additional problems in donor site along with disappointing results. tissue engineering is a promising solution for a widespread range of defects and disorders. it is reasonable to utilize this novel technolog...

We investigated whether low-level light irradiation prior to transplantation of adipose-derived stromal cell (ASC) spheroids in an animal skin wound model stimulated angiogenesis and tissue regeneration to improve functional recovery of skin tissue. The spheroid, composed of hASCs, was irradiated with low-level light and expressed angiogenic factors, including vascular endothelial growth factor...

The potential use of human mesenchymal stem cells for therapeutic applications implies large scale in vitro culture, increasing the probability of genetic instability and transformation. We examine here the incidence of unbalanced and balanced chromosome rearrangements in polyclonal and single cell-derived cultures of human adipose stem cells to senescence. G-banding karyotyping of the polyclon...

Adipose tissue stroma contains a population of mesenchymal stem cells (MSC) promote new blood vessel formation and stabilization. These adipose-derived stem cells (ASC) promote de novo formation of vascular structures in vitro. We investigated the angiogenic factors secreted by ASC and discovered that glial-derived neurotrophic factor (GDNF) is a key mediator for endothelial cell network format...
