in this syudy a continuous bovine kidney cell line derived from a primary bovine kidney cells was established for the first time in iran. the cells were originating from two-day-old normal male calf of holstein breed. the cell cultures were continuously passaged following complete proliferation of primary cells. the specific properties or characteristics of the cell were defined using cytogene...

Patients with classic fibrodysplasia ossificans progressiva, a disorder characterized by extensive extraskeletal endochondral bone formation, share a recurrent mutation (R206H) within the glycine/serine-rich domain of ACVR1/ALK2, a bone morphogenetic protein type I receptor. Through a series of in vitro assays using several mammalian cell lines and chick limb bud micromass cultures, we determin...

Ventricular dilation after myocardial infarction can cause heart failure. Increasing strength and elasticity in the infarct region might prevent ventricular dilation. Because elastin provides strength, extensibility, and resilience to tissues and maintains tissue architecture, we studied the effect of elastin expression in the infarct on scar expansion and heart function. COS-7 cells transfecte...

the aim of this study was to develop a novel multifunctional nanoparticle, which encapsulates spion and gemcitabine in plga±peg to form multifunctional drug delivery system. for this aim, super paramagnetic iron oxide nanoparticles (spions) were synthesized and encapsulated simultaneously with gemcitabine (gem) in plga±peg copolymers via w/o/w double emulsification method. optimum size and enca...

Dry age-related macular degeneration and Stargardt disease undergo a known toxic mechanism caused by carbonyl oxidative stresses (COS). This is responsible for accumulation in the retinal pigment epithelium (RPE) of A2E, main pyridinium bis-retinoid lipofuscin component. Previous studies have shown that stress cells could be reduced an alkyl-phloroglucinol-DHA conjugate (lipophenol). Here, we p...

The generation of mature and vascularized human pluripotent stem cell-derived cardiac organoids (hPSC-COs) is necessary to ensure the validity drug screening disease modeling. This study investigates effects cellular aggregate (CA) stemness self-organization on hPSC-COs elucidates mechanisms underlying organoid (CO) maturation vascularization. COs derived from 2-day-old CAs with high (H-COs) 5-...

background: the rh antigens are expressed as parts of a protein complex in the rbc membrane. this complex is a tetramer, consisting of two molecules of rhag and two molecules of rh proteins. to express rhd in rbc membrane, expression of rhag is essential. this co-expression only occurs in the erythroid lineage. k562 cell line has an erythroid lineage. materials and methods: cord blood was used ...

Background: Breast cancer is a common cause of brain metastasis. Although breast has relatively high survival rates, its rate after metastasis to the lower. Conventional two-dimensional cell culture models and animal are widely used in metastatic research, these have tremendously contributed understanding this disease. However, some limitations, such as different physiological features genetic ...
