objective: we evaluated structural and functional changes of fresh and frozen-thawed adult mouse spermatogonial stem cells following auto-transplantation into gamma-irradiated testes. materials and methods: in this experimental research, the right testes from adult mice (n=25) were collected, then sertoli and spermatogonial cells were isolated using two-step enzymatic digestion, lectin immobili...
Stem cells are a good alternative for regenerative medicine because of their characteristics such as self-renewal and differentiation potential. They are classified into different types of stem cells including embryonic stem cells, induced pluripotent stem cells, multipotent stem cells, and ultimately uni-potent stem cells. Mesenchymal stem cells extracted from adult tissues. Due to the lack of...
هم کشتی سلول های بنیادی با یکدیگر دریچه های جدیدی را فرا روی محققین علم سلول درمانی گشوده است. با این روش میتوان سبب بهبود شرایط کشت و تمایز بهتر سلول های بنیادی شد. فاکتورهای رشد عصبی (neurotrophic factors,ntfs)، مولکول هایی هستند که نقش های بسیار حیاتی در بقا، تکثیر و تمایز سلول های بنیادی دارند. هدف از این تحقیق ارزیابی بیان فاکتورهای نوروتروفیک (gdnf، bdnf، cntf،nt3) و سرعت تکثی...
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...
Despite the significant advances in regenerative medicine, wound healing has remained a challenging clinical problem. Skin is the largest human organ with many vital functions; therefore, any damage to its normal structure should be treated as soon as possible. Easy access to skin stem cells has created a lot of excitement in therapeutic applications. “Cell therapy” is considered a novel method...
background the mammary gland in humans is a dynamic organ that undergoes significant developmental changes during pregnancy, lactation, and involution. stem cells derived from human breast milk possess the adult stem cell-like characteristics such as self-renewal, proliferative and differentiate potential. this source of stem cells avoids invasive procedures and the ethical controversy of embr...

The possibility to reprogram somatic human cells will greatly and deeply change genetic approach and allow the development of new tools to study genetics diseases. Indeed, our ability to study human genetic diseases suffers from the lack of valid in vitro models. The latter should (i) be originating from human primary cells, (ii) be able to self-renew for a long time and (iii) be able to differ...
Background Degenerative retinal diseases, including age related macular degeneration, glaucoma, and hereditary retinal dystrophies are major causes of blindness. The principal defect in these diseases is cell loss which is amenable to both cell based neuroprotective and neuroregenerative therapies. To briefly review the lines of research and potential candidates for cell based therapies among ...
