introduction: the p19 line of embryonal carcinoma cells develops into neurons, astroglia and fibroblasts after aggregation and exposure to retinoic acid (ra). dehydroepiandroesteron (dhea) is a neurosteroid, can increase proliferation of human neural stem cell (nsc) and positively regulated the number of neurons produced. this study was initiated to assess the effect of dhea on neural progenito...

Stem cells are undifferentiated cells with the ability to divide and differentiate into distinct cell types. The source of these cells is from embryos and adults, that each cell has its own specific characteristics. For nearly decades, experimental studies have been conducted to use these types of cells to treat various diseases. Parkinson's disease is one of the most common neurodegenerative d...

Objective(s):Estrogen is a sexual hormone that has prominent effects on reproductive and non-reproductive tissues. The aim of this study is to evaluate the effects of estrogen on the proliferation and neural differentiation of human adipose derived stem cells (ADSCs) during neurogenic differentiation. Materials and Methods: Isolated human ADSCs were trans-differentiated in neural induction med...

Arm grooves of star-fish have mesenchymal stem cells derived from adipose tissue cell. Widespread studies have shown that stem cells derived from adipose-derived mesenchymal stem cell from bone marrow have many similarities in terms of the ability to differentiate into a variety of tissues. Most of the animals live in warm and shallow waters and the waters of this feature is that it is low in d...

هدف: دمیلیناسیون آکسونها در cns بزرگسالان جوان، مشخصه برجسته ms می باشد. دستگاه بینایی در بیش از 70 درصد بیماران متأثر می گردد. تا کنون درمان کاملی برای ms وجود نداشته است. رمیلیناسیون خودبخودی در ms روی می دهد، اگر چه ناکامل است. سلولهای بنیادی عصبی در مغز بزرگسالان ظرفیت فیزیولوژیک قابل توجهی را فراهم نموده اند. امکان مشارکت این ظرفیت بالقوه در پاسخ به القا آسیب دمیلینه کننده تجربی در ناحیه ک...

Adult neurogenesis is a process of producing nerve cells from their progenitor that occurs in some areas in the brain such as the hypothalamus. Low activity in this area plays a role in neural degeneration and diseases such as multiple sclerosis, epilepsy and depression. MS is a neurodegenerative disease with a permanent disability that the main reason for it is axonal degeneration and neuronal...

Background: Pregnenolone as a precursor of steroid hormones, can be effect on inflammatory condition to maintain immune homeostasis. The previous study shows that pregnenolone levels are reduced in neuro inflammatory disease, which emphasizes its role in neuroprotection and nerve regeneration and its anti-inflammatory role  So the aim of this study try to investigated effect of pregnenolone on ...

Adult neurogenesis, a concept emergent in the late 1990s, is the generation of new neurons in the adult brain. This process occurs thank to cells who have this proliferative feature, named as Neural Stem Cells (NSCs). Neural Stem Cells (NSCs) are primary progenitors who can generate the two neural types (neurons and glia). Classically it was assumed that NSCs are only present in the embryo, but...

Background and Objective: One of the approaches for treatment of demylination diseases is cell therapy. Stem cells have been used as a source for generating oligodendrocyte. In a previous communication, the oligodendrocyte-like cells (OLCs) were generated from bone marrow stromal cells (BMSCs) using preinducers (dimethyl sulfoxide and retinoic acid) and induction protocol (PDGF, bFGF, heregulin...
