The stromal-vascular cell fraction (SVF) of adipose tissue can be an abundant source of both multipotent and pluripotent stem cells, known as adipose-derived stem cells or adipose tissue-derived stromal cells (ADSCs). The SVF also contains vascular cells, targeted progenitor cells, and preadipocytes. Stromal cells isolated from adipose tissue express common surface antigens, show the ability to adhere to plastic, and produce forms that resemble fibroblasts. They are characterized by a high proliferation potential and the ability to differentiate into cells of meso-, ecto- and endodermal origin. Although stem cells obtained from an adult organism have smaller capabilities for differentiation in comparison to embryonic and induced pluripotent stem cells (iPSs), the cost of obtaining them is significantly lower. The 40 years of research that mainly focused on the potential of bone marrow stem cells (BMSCs) revealed a number of negative factors: the painful sampling procedure, frequent complications, and small cell yield. The number of stem cells in adipose tissue is relatively large, and obtaining them is less invasive. Sampling through simple procedures such as liposuction performed under local anesthesia is less painful, ensuring patient comfort. The isolated cells are easily grown in culture, and they retain their properties over many passages. That is why adipose tissue has recently been treated as an attractive alternative source of stem cells. Essential aspects of ADSC biology and their use in regenerative medicine will be analyzed in this article.

Over the past few decades, trans-resveratrol has received widespread attention as a preventive agent for numerous diseases. Several studies have demonstrated that it has significant biological and pharmacological properties. Trans-resveratrol has been reported to possess anti-oxidant, anti-inflammatory, anticarcinogenic, antidiabetic, anti-aging, cardioprotective and neuroprotective properties, which can be relevant in chronic diseases and longevity in humans. The aim of the present study was to investigate the rate and extend of absorption, and also the safety of resveratrol following a single 500 mg oral dose. This was an open label, single dose, one period, bioavailability study in 15 healthy volunteers under fasting conditions. Blood samples were collected at predefined time points up to 24 h after resveratrol administration, and plasma concentrations of resveratrol and its conjugated (glucuronated and sulphated) metabolites were determined using a validated high performance liquid chromatography/tandem mass spectrometry method. Pharmacokinetic parameters, including Cmax, AUC0-t, AUC0-inf, Tmax, T1/2 and MRT, were determined from plasma concentration-time profiles and found to be in good agreement with previously reported data. Cmax and AUC0-inf were lower for resveratrol when compared with the values for its glucuronated and sulphated metabolites. Cmax for resveratrol, glucuronated resveratrol and sulphated resveratrol were 71.2±42.4 ng/ml, 4,083.9±1,704.4 ng/ml and 1,516.0±639.0 ng/ml, respectively, while the AUC0-inf values were 179.1±79.1 ng/ml, 39,732.4±16,145.6 ng/ml and 14,441.7±7,593.2 ng/ml, respectively. No adverse reactions associated with resveratrol were reported during the study. The plasma concentrations of resveratrol (free and conjugated) were in agreement with those mentioned in the literature, and were adequate to promote the pharmacological activities of resveratrol. In conclusion, resveratrol 500 mg tablets were well-tolerated by all participants of the study.

Facial rejuvenation is rapidly evolving sector in the field of facial aesthetics. There is a wide variety of dermal fillers and many more are in development. Over the past few years, the study of adult-derived stem cells has become a very active area of research. Adult stem cells are an attractive option for volume restoration and facial rejuvenation. Adult stem cells are isolated from adipose tissue-adipose derived stem cells and have mesodermal, ectodermal, and endodermal potentials. Adipose-derived stem cells could conceivably be an alternative to pluripotent embryonic stem cells and could play a critical role in the rapidly expanding fields of tissue engineering and regenerative medicine. This article reviews the history of soft tissue augmentation using adipose tissue grafting and the advent of using adipose-derived stem cells. The state-of-the-art stem cell isolation technique as well as anticipated future therapeutic indications are also addressed.

Glycation products accumulate during aging of slowly renewing tissue, including skin, and are suggested as an important mechanism underlying the skin aging process. Adipose-derived cells are widely used in the clinic to treat ischemic diseases and enhance wound healing. Interestingly, adipose-derived stem cells (ASCs) are also effective in anti-aging therapy, although the mechanism underlying their effects remains unknown. The purpose of the present study was to examine the anti-aging effect of ASCs in a D-galactose-induced aging animal model and to clarify the underlying mechanism.


Six-week-old nude mice were subcutaneously injected with D-gal daily for 8 weeks. Two weeks after completion of treatment, mice were randomized to receive subcutaneous injections of 106 green fluorescent protein (GFP)-expressing ASCs, aminoguanidine (AG) or phosphate-buffered saline (PBS). Control mice received no treatment. We examined tissue histology and determined the activity of senescence-associated molecular markers such as superoxide dismutase (SOD) and malondialdehyde (MDA).


Transplanted ASCs were detectable for 14 days and their GFP signal disappeared at day 28 after injection. ASCs inhibited advanced glycation end product (AGE) levels in our animal model as well as increased the SOD level and decreased the MDA level, all of which act to reverse the aging phenotype in a similar way to AG, an inhibitor of AGE formation. Furthermore, ASCs released angiogenic factors in vivo such as vascular endothelial growth factor, suggesting a skin trophic effect.


These results demonstrate that ASCs may contribute to the regeneration of skin during aging. In addition, the data shows that ASCs provide a functional benefit by glycation suppression, antioxidation, and trophic effects in a mouse model of aging.
