Background: One of the key questions in biochemistry is why cell becomes aged and what are the involved factors? Why cell growth is stopped after some divisions and cells become senescent? This occurs in a greater frame in the whole body and cells dye after a while. Androgenetic alopecia (AGA) is characterized by a loss or decrease in hair follicle size, which could be related to the loss of ha...

the identification of multipotential mesenchymal stem cells (mscs) derived from adult human tissues such as bone marrow and connective tissues has provided exciting prospects for cell-based tissue engineering and regeneration. this review article focuses on the biology of mscs, their differentiation potentials in vitro and in vivo, and their application in tissue engineering. our current unders...

Background: In the present study, we hypothesized that conditioned medium (CM) derived from mesenchymal stem cells attenuates the brain oxidative stress in sepsis induced by the cecal ligation and puncture (CLP) model. Methods: This study was performed in the Department of Physiology at Tehran University of Medical Sciences from August 2018 to April 2019. Conditioned medium was collected from ...

objective(s):some evidence showed that calcitriol has an important role in regulating growth and differentiation of mesenchymal stem cells (mscs). however, the interaction between mesenchymal stem cells and macrophage is not clear yet.  the current study was done to investigate the in vitro effects of calcitriol on the interactions between bone marrow-derived mscs and rat macrophages. materials...

Background and Aims: Mesenchymal stem cells (MSCs) are a preferred cell source for the generation of hepatocyte-like cells in regenerative medicine. They can be isolated from different sources, including adipose tissues. The Raman spectroscopy approach was evaluated for quick and efficient identification of MSCs differentiation status and a broader perspective on cell differentiation. Material...

background: mesenchymal stem cells (mscs) are multipotent cells that can be collected from different sources. under specific conditions, mscs can be differentiated to tissue specific cells in vitro. human umbilical cord mesenchymal stem cells (hucmscs) can easily be harvested and cultured in in vitro conditions. production of germ cells from mesenchymal stem cells is a very interesting and prom...

stem cells from human exfoliated deciduous teeth (shed) have been introduced recently and  possess characteristics similar to  mesenchymal stem  cells (mscs). because of  their convenient accessibility and safety of harvest, shed can be a preferable source for the ever- increasing mscs’ applications. while they are new, their immunoproperties have not been adequately studied. in this study, we ...

introduction: mesenchymal stem cells (mscs) hold great promise in the field of regenerative medicine.although originally isolated from bone marrow, mscs have since been obtained from a variety of adult and neonatal tissues including the adipose tissue. stemness and multipotential features of mesenchymal stem cells (msc) has been highlighted in many studies but there are many dark aspects in exc...
