Introduction: Satellite cells are known as the main regenerative cell type in skeletal muscles. Our study established a modified digestion and preplating method for the isolation of slow or weak adherent cells for the enrichment of satellite cells. Low-survival rate of these primary stem cells prompted us to address whether cell culture medium substitution might change cell viability status. M...
Introduction: Skeletal muscles account for about 40% of the total body weight. Every year, hundreds of people lose at least part of their muscle tissue due to illness, war, and accidents. This can lead to disruption of activities such as breathing, movement, and social life. To this end, various therapeutic strategies such as medication therapy, cell therapy and tissue transplantation have been...
Increasing development of nanotechnology and the production of nanostructured materials have led to many nanoparticles enter into the environment. Iron oxide nanoparticles are one of the most widely used nanomaterial that their widespread application has been accompanied with concern. The purpose of this study was to evaluate the iron bioaccumulation and histopathology in the muscle, skin and s...
introduction: we did this study because there were a few studies about aorto-branch junction. methods: four light microscope and electron microscope study, the abdominal aorta, renal artery, and the adjoining right and left renal arteries were dissected out from 4 neonate dogs. results: based on the results, there is only one cell type in the tunica intima of endothelium in both arteries. in ab...
satellite cells (scs) are the most abundant skeletal muscle stem cells. they are widely recognized for their contributions to maintenance of muscle mass, regeneration and hypertrophy during the human life span. these cells are good candidates for cell therapy due to their self-renewal capabilities and presence in an undifferentiated form. presently, a significant gap exists between our knowledg...
Background: Type 1 diabetes is associated with decreased skeletal muscle capillary and improper regulation of angiogenesis pathways in skeletal muscle. This research intended to study the effect of resistance training and endothelial stem cell injection on βeta-actin, phosphorylated and total AKT of skeletal muscle in type 1 diabetic rats. Methods: In this experimental study, 36 male Wistar ra...
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 ...
هدف: کشت سلول های اسپرماتوگونی و تولید سلول های پر توان embryonic stem cells (es like cells) که دارای قابلیت بازسازی و تولید هرسه نوع لایه زایای جنینی می باشند، این سلول ها را به عنوان منبع کافی و جدیدی برای سلول درمانی و ترمیم در بیماریها از جمله بیماریهای نورودژنراتیو پیشنهاد می دهد. در تحقیق حاضر تمایز سلول های اسپرماتوگونی موش به سلول های شبه الیگودندروسیت و نقش آنها درمیلین سازی پس از پیون...
in this study, effects of buthus eupeus venom on chick biventer cervices nerve-muscle preparation were investigated by twitch tension method. the venom, at 1.3 ?g/ml, increased contractile responses in indirect stimulations. these effects were milder in direct muscle stimulations. it also caused significant enhancement in postjunctional sensitivity as assessed by responses to exogenous acetylch...
Sphingolipid metabolism was examined in guinea-pig airway smooth muscle cells stimulated by platelet-derived growth factor (PDGF) and 4β-phorbol 12- myristate 13-acetate (PMA), as mitogens and bradykinin (BK) as non-mitogen. Stimulation of the cells by PMA and PDGF for 60 min. at 37°C induced the following changes in sphingolipid metabolites: in cells prelabeled with PH] palmitate, a 1.2 f...
