[ 1 ] - Effect of Sambucus ebulus extract on neural stem cell prolifration under oxidative stress condition
Background and Aim: Recently, several studies have indicated that the central nervous system has the capacity for endogenous repair. But, the proliferation capacity of endogenous neural stem cells (NSCs) isn’t sufficient for the treatment of neurodegenerative diseases. So, it sounds that stimulation of endogenous NSC proliferation is essential for neuroregeneration. The aim of this study ...
[ 3 ] - An Efficient Protocol for Embryonic Carcinoma Cells P19 Differentiation to Cardiomyocytes Using Oxytocin as Inducer
Background: The capability of embryonic carcinoma cells P19 in differentiation to Cardiomyocyte was examined through inducing effects of Oxytocin (OT) and 5-Azacytidin (5Az) individually and compared with each other in laboratory condition. Materials and Methods: P19 Embryoid Bodies (EBs) was formed through hanging drops method. Then, EBs were treated with (5Az) or (OT) and the EB medium (Ct...
[ 4 ] - Spermatogonia stem cells: A new pluripotent source for repairment in regenerative medicine
Recently new reports have proved the pluripotency of spermatogonial stem cells (SSCs) derived from male gonad. This pluripotent stem cells resembled Embryonic stem cells recognized as Embryonic Stem like cells (ES like cells). ES like cells forms sharp edge colonies that are immunopositive to pluripotency markers and have differentiation capacity to Ectodermal, Mesodermal and Endodermal layers....
[ 5 ] - Expression of Spermatogonial and Pluripotency Markers in Spermatogonial Stem Cells after Treatment with Different Culture Factors
Background: As condition and component of culture determine fate map of spermatogonial stem cells (SSCs), the aim of this study was to evaluate of growth factors GDNF, LIF and RA on proliferation and differentiation of SSC. Materials and Methods: SSCs were cultured in two groups: The first group GDNF and LIF and the second group RA. The number of clumps and colony formation was monitored dur...
[ 6 ] - تاثیر گنادوتروپین جفتی انسانی بر اثرات تخریبی ناندرولون دکانوات بر روی پارامترهای اسپرم موش صحرایی بالغ
زمینه و هدف: ناندرولون دکانوات از مهم‌ترین داروهای آنابولیک آندروژنیک استروئید(AAS) است. از طرفی هورمون گنادوتروپین جفتی انسان(hCG) موجب تحریک ترشح تستوسترون و افزایش تولید آندروژن می‌گردد. بنابراین هدف از این مطالعه بررسی تغییرات ناشی از تاثیرات این هورمون بر اثرات تخریبی دارویی ASSدر بافت‌ها و سلول‌های دستگاه تناسلی نر موش صحرایی بود. روش بررسی: در این مطالعه تجربی، موش‌های صحرایی نر به پنج...
[ 7 ] - تأثیر DMSO در القای تمایز کاردیومیوسیت ها از سلول های کارسینومای جنینی P19در شرایط آزمایشگاهی
مقدمه: در مطالعه حاضر توانایی تمایز سلول های کارسینومای جنینی P19در غلظت های مختلف DMSO به کاردیومیوسیت ها مورد ارزیابی قرار گرفت. مواد و روش ها: جهت تمایز سلول های P19، اجسام شبه جنینی(Embryoid Bodies,EBs) به روش قطرات آویزان طی 2 روز تشکیل شدند. سپسEBs به مدت 18 روز تحت القائات غلظت های مختلف DMSO 1/0 درصد، 5/0 درصد، 1 درصد، 5/1 درصد، 2 درصد قرار گرفتند. طی تمایز تعداد ضربان در دقیقه هر سه ر...
[ 8 ] - محافظت نورون های دوپامینرژیکی به وسیله جینکولاید در بیماری پارکینسون مدل 6-هیدروکسی دوپامین
Background and purpose: Parkinson's disease (PD) is a prevalent movement disorder in elderly with progressive motor complications due to antioxidant defense system deficiency and accumulation of degraded proteins in dopaminergic neurons of midbrain. Ginkgolide is biologically active terpenic lactones as a polyphenol, with potent antioxidant and anti-inflammatory properties. The present study ai...
[ 10 ] - The effect of BMP4 on mouse embryonic stem cell proliferation and differentiation into primordial germ cells
Background and Aim: Artificial gamete production from stem cells is a novel strategy for treatment of infertility. Among various stem cell sources, embryonic stem cells (ESC) can be considered as an appropriate source for in vitro formation of germ cells. In this study we evaluated the effect of BMP4 on proliferation and differentiation of mouse embryonic stem cells into primordial germ cells (...
[ 11 ] - Cardiogel as an Instructive Microenvironment for in vitro Differentiation of Bone Marrow- Derived Mesenchymal Stem Cells into Cardiomyocytes
Background: Stem cell therapy has been developed as an effective treatment method for the heart failure. Also, extracellular matrix has shown the positive effects in stem cell differentiation and myocardial tissue organization. Cardiogel is a native cardiac extracellular matrix (ECM) derived from cardiac fibroblasts. In the present study the role of cardiogel is examin...
[ 12 ] - Nerve Growth Factor and the Trans-differentiation of Human Dental Pulp Stem Cells Into Cholinergic-like Neurons
Introduction: Cell therapy has been widely considered as a therapeutic approach for neurodegenerative diseases and nervous system damage. Cholinergic neurons as one of the most important neurons that play a significant role in controlling emotions, mobility, and autonomic systems. In this study, human dental pulp stem cells (hDPSCs) were differentiated into the cholinergic neurons by β-mercapto...
[ 13 ] - PuraMatrix hydrogel enhances the expression of motor neuron progenitor marker and improves adhesion and proliferation of motor neuron-like cells
Objective(s): Cell therapy has provided clinical applications to the treatment of motor neuron diseases. The current obstacle in stem cell therapy is to direct differentiation of stem cells into neurons in the neurodegenerative disorders. Biomaterial scaffolds can improve cell differentiation and are widely used in translational medicine and tissue engineering. The aim...
[ 14 ] - An Efficient In Vitro Culture System To Amplify Spermatogonia Stem Cell Markers
Background: Proliferation of spermatogonial stem cells (SSCs) can be a treatment for infertile men. Here, we design an efficient method based on culturing in the presence of Sertoli cells to improve the expression level of some specific spermatogonia stem cell genes during two weeks post culture. Materials and Methods: Cells were derived from neonatal (2-6 days old) mice testes and were cultur...
[ 15 ] - A Novel in vitro Co-culture Systems on Differentiation of Embryonic Stem Cells into Oocyte-like Cells in an in vivo Manner
Background:Differentiation of Embryonic Stem Cells into Oocyte-like cells in vitro is challenging. Successful derivation of oocyte from stem cells can provide an alternative source for curing ovogenesis problems.
