Endogenous Adult-Derived Telomerase-Positive Stem Cells

بررسی امکان مشارکت توان فیزیولوژیک مغز (endogenous adult neural stem cells) در ترمیم غلاف میلین عصب بینایی و کیاسمای دمیلینه شده با لیزولسیتین در موش صحرایی

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 Mesenchymal Stem Cells Derived from Embryonic Stem Cells

Mesenchymal stem cells (MSC) are useful in cell therapy and stem cell research but they have a limited lifespan in culture. Our goal was to develop a unique and limitless supply of mesenchymal stem cells derived from human embryonic stem cells, opening up new uses and enhance existing uses of these important cell types. For any application that uses large quantities of MSC, such as high through...

Telomeres and telomerase in adult stem cells and pluripotent embryonic stem cells.

Telomerase expression is silenced in most adult somatic tissues with the exception of adult stem cell (SC) compartments, which have the property of having the longest telomeres within a given tissue. Adult SC compartments suffer from telomere shortening associated with organismal aging until telomeres reach a critically short length, which is sufficient to impair SC mobilization and tissue rege...

Adult Mesenchymal Stem Cells for Tissue Engineering

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...
