Full description

Skin aging is a complex biological process that can be categorized into either extrinsic or intrinsic aging. Intrinsic aging is an inherent degenerative process caused by decreased proliferative capacity leading to cellular senescence. Extrinsic aging is caused by factors such as UV radiations, smoking and alcohol consumption.The physiological changes associated with aging of the skin are manifested in xerosis, dramatic loss of skin elasticity due to damage to collagen and elastin fibers; as well as barrier function, modification of rhytides and deficiencies in the regenerative property of the skin. All of which ultimately result in thinning of the skin, malar fat atrophy and pigmentary changes.Aging skin undergoes thinning of the epidermis that is caused by reduction of vascularity and hydration. On average, the thickness of the epidermis is reduced by about 6.4% during each decade of life.Skin aging effects can be assessed based on the skin appearance (texture and roughness, fine lines and wrinkles), structure, elasticity, hydration and barrier function. Many new non-invasive or minimally invasive bioengineering advances in recent years have enabled the quantitative analysis of skin properties during the aging processRecently, adult stem cells such as mesenchymal stem cells (MSCs) have been used in variable dermatologic conditions due to its regenerative properties such as wound healing, rejuvenation, acne scar and hair fall treatment. Different types of MSCs could be derived from different tissues as for example; bone marrow stem cells (BMSCs), adipose tissue-derived stem cells (ADSCs), and skin-derived stem cells (SDSCs)Adipose tissue derived stem cells are currently favorable compared to other types of adult stem cells as the procedure is easy, safe with minimal donor site morbidity. The process of obtaining a considerable amount of adipose tissues sufficient to use in skin regeneration is highly appealing due to its relative availability and accessibility. They secrete variable growth factors that affect surrounding environment as vascular endothelial growth factor (VEGF), platelet derived growth factor (PDGF), insulin like growth factors (IGF) and others
