Objective: Extensive research has been done to assess the efficacy of herbs for treating different disorders. Dorema ammoniacum (D. ammoniacum) is used in folk medicines for various goals. The application of herbs in medicine is accompanied by harmful effects. Chick embryo is considered a suitable model for assessing drugs toxicity. The present study aimed to evaluate the chang...

Most Lophiiformes including Lophius species are considered to spawn egg masses called an “egg veil” or ribbon” composed of numerous mucoid chambers. However, eggs have been rarely collected in the field and thus little is known about their biological features. Here we examined embryonic development litulon also effects water temperature on from veils field. Embryonic was observed late cleavage ...

Stem cells are undifferentiated that can proliferate, regenerate, develop into differentiated cells, and produce a variety of tissues. Embryonic stem adult or somatic pluripotent the three types cells. Another classification is totipotent, multipotent, unipotent cell treatment has possibility treating degenerative disorders, cancer, restoration damaged tissues, all which now have no restricted ...

background new research proposes the pluripotency of spermatogonial cells obtained from testis. these spermatogonia-derived stem cells are called embryonic stem-like cells that express embryonic stem cell markers and differentiate to the three germ layers. objectives the aim of the present study was to generate embryonic stem-like cells from neonatal mouse testis. materials and methods the test...

teratomas are tumors originated from mature or immature tissues. teratomas are made up of one embryonic layer or all three embryonic layers (endoderm, mesoderm, or ectoderm). herein we report a 41-year-old man who presented with vertigo, vomiting, and tinnitus. after physical examination, laboratory evaluation and performing computed tomography, cholesteatoma was diagnosed, however, during radi...

background: transplantation approaches are interventions currently available to apply to the devastating problem of spinal cord injury (sci). olfactory ensheathing cell (oec) and embryonic stem cell (esc) are considered to be promising therapeutic strategies . in this study, we compared the potential use of oecs and neurally pre-differentiated escs in contusion spinal cord. methods: oecs were h...

background:   objective: this study presents an economical and simple co-culture system for pluripotent stem cells generation from neonatal mouse testis   materials and methods: isolated testicular cells were cultured in dmem/f12. characteristics of the isolated cells and obtained es-like cell were immune-cytochemically confirmed by examining the presence of plzf, vimentin, oct4 and nanog prote...

Background: Apoptosis is induced by several factors and has an important role in embryonic development. Since vitrification-induced embryonic damages could be resulted from an increase in apoptosis occurrence,the aim of the present study is to investigate the effect of vitrification on induction of apoptosis in blastocysts. Materials and Methods: For this purpose 20 balb-c mice superovulated an...
