Epigenetic Dysregulation in Mesenchymal Stem Cell Aging and Spontaneous Differentiation
BACKGROUND Mesenchymal stem cells (MSCs) hold great promise for the treatment of difficult diseases. As MSCs represent a rare cell population, ex vivo expansion of MSCs is indispensable to obtain sufficient amounts of cells for therapies and tissue engineering. However, spontaneous differentiation and aging of MSCs occur during expansion and the molecular mechanisms involved have been poorly un...
متن کاملAdult stem cell and mesenchymal progenitor theories of aging
Advances in medical science and technology allow people live longer lives, which results in age-related problems. Humans cannot avoid the various aged-related alterations of aging; in other words, humans cannot remain young at molecular and cellular levels. In 1956, Harman proposed the "free radical theory of aging" to explain the molecular mechanisms of aging. Telomere length, and accumulation...
متن کاملIntestinal inflammation and stem cell homeostasis in aging Drosophila melanogaster
As a barrier epithelium, the intestinal epithelium has to coordinate physiological functions like digestion and nutrient resorption with the control of commensal bacteria and the prevention of pathogenic infections. It can therefore mount powerful innate immune and inflammatory responses, while, at the same time, maintaining tissue homeostasis through regenerative processes. How these different...
متن کاملAging of mesenchymal stem cells.
The role of adult mesenchymal stem cells (MSC) in tissue maintenance and regeneration has received significant attention of late. Questions arise to what extent these cells are either subject to, or causes of aging; whether age-related changes in these cells are due to intrinsic factors or induced by the somatic environment. This review collates and examines recent data in support of these diff...
متن کاملMesenchymal Stem Cell Purification from the Articular Cartilage Cell Culture
Objective Articular cartilage as an avascular skeletal tissue possesses limited capacity to heal. On the other hand, it is believed that the regeneration capacity of each tissue is largely related to its stem cell contents. Little is known about the presence of mesenchymal stem cells in articular cartilage tissue. This subject is investigated in the present study. Materials and Methods Artic...
