Background and Objective: In neurodegenerative disorders, oxidative stress mediated by reactive oxygen species is strongly associated with increased neuronal damages that lead to apoptosis. Pro-apoptotic and anti-apoptotic gene expressions were changed during cell differentiation that affect cell viability and differentiation. This study was conducted to determine the effects of hydrogen peroxi...

Purpose: Differentiation of mouse embryonic stem cells into Insulin secreting endocrine cells. Materials and Methods: In this study, Royan B1 mouse embryonic stem cell (derived from C57BL/6 mouse) were used. In directed differentiation method, embryonicstem cells after embryoid bodies formation were differentiated into insulin secreting cells. Nestin positive cells were obtained after culture ...

Stem cells are undifferentiated biological cells that can differentiate into more specialized cells and divide (through mitosis) to produce more stem cells (self-renew). In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. Mesenchymal stem cells (MSCs) are ...

objective(s): stem cell differentiation into different cell lineages depends upon several factors, cell cycle control elements and intracellular signaling elements, including p15ink4b and p16ink4a genes. epigenetics may be regarded as a control mechanism which is affected by these factors with respect to their promoter structure.   materials and methods: the cd34 + cord blood stem cells were pu...

introduction: embryonic stem (es) cells are pluripotent cells derived from inner cell mass of blastocyst. these cells can product any cell by spontaneous or directed differentiation. this study was started to produce neuron cells by directed differentiation of new murine es cell line in vitro. materials and methods: murine es cells (royan b1 derived from c57bl/6 strain) were used for in vitro n...

Objective(s) The use of co-culture cells as well as extra cellular matrix are among those strategies that have been employed to direct mesenchymal stem cell (MSC) bone differentiation in culture. In this regard, there is no study considering the effects of Matrigel on mesenchymal stem cell (MSC) in vitro bone differentiation. This was the subject of the present study. Materials and Methods ...

Several signaling pathways and transcription factors control the cell fate in its in vitro development and differentiation. The orchestrated use of these factors results in cell specification. In coculture methods, many of these factors secrete from host cells but control the process. Today, transcription factors required for retinal progenitor cells are well known, but the generation of these ...

Background: Hair follicle stem cells (HFSCs) located in the bulge area has shown to be highly proliferative and could differentiate into neurons, glia, smooth muscle cell, and melanocytes in vitro. Simvastatin is an HMG-CoA reductase inhibitor that exerts pleiotropic effects beyond simple low-density lipoprotein lowering and has a similar impact on the differentiation of bone marrow stromal cel...
