Regenerative capacity of mammals is limited and can rarely regenerate a specific organ or tissue fully. Due to these limitations, regenerative medicine seeks efficient and safe cell sources for regeneration of damaged tissues and organs or treatment for incurable diseases. Human embryonic stem cells (HESCs) hold two important properties called self renewal and pluripotency. However, the use of ...

background mesenchymal stem cells (mscs) are ideal candidates for treatment of diseases. amniotic membranes are an inexpensive source of mscs (am-msc) without any donor site morbidity in cell therapy. adipose tissue derived stem cells (ascs) are also suitable cells for cell therapy. there is discrepancy in cd271 expression among mscs from different sources. in this study, the characteristics of...

Stem cell-based cellular therapy is a promising tool for the treatment of pathological conditions with underlying severe tissue damage or malfunction like in chronic cardiovascular, musculoskeletal, inflammatory conditions. One biggest technical challenges use natural stem cells, however, prevention their premature senescence during therapeutical manipulations. Culturing cells under hypoxic bel...

a common pathological process that occurred after brain injury is gliosis. gliosis involves the activation of glial cells to proliferate and become hypertrophic to occupy the injured brain areas. in order to form a defense system against the invasion of micro-organisms and cytotoxins into surrounding tissue, glial cells including astrocytes and microglia undergo reactive response to injury. neu...

traumatic brain injury (tbi) is physical damage to the brain structure which has a high global rate of mortality and morbidity. tbi can cause intense inflammatory response due to accumulation of leukocytes in cerebral matrix and activation of microglia. microglia can differentiate into m1 macrophages or m2 macrophages following the changes in biochemical properties of brain tissue. m1 sub type ...

Traumatic brain injury (TBI) is physical damage to the brain structure which has a high global rate of mortality and morbidity. TBI can cause intense inflammatory response due to accumulation of leukocytes in cerebral matrix and activation of microglia. Microglia can differentiate into M1 macrophages or M2 macrophages following the changes in biochemical properties of brain tissue. M1 sub type ...

Spinal cord injury (SCI) is a debilitating disease which leads to progressive functional damages. Because of limited axonal regeneration in the central nervous system, there is no or little recovery expected in the patients. Different cellular and molecular approaches were investigated in SCI animal models. Cellular transplantation of stem cells can potentially replace damaged tissue and provid...

background : cancer stem cells are a subgroup of tumor cells that have the capability for self-renewal and differentiation and are characterized by multiple markers. several studies have been conducted to identify these cells in colorectal cancer, including stem cell marker cd24. this study has evaluatedtheassociation of cd24 expression with clinicopathologic features and survival in an immunoh...

background: mesenchymal stem cells (mscs) with their potential to differentiate into mesodermal and non-mesodermal lineages have several immunomodulatory characteris-tics. these properties make them promising tools in cell and gene therapy. objective: to evaluate the potential therapeutic applications of autologous msc in improving clinical manifestations of ms patients. methods: ten patients w...
