Review of Differentiation and Proliferation of Primordial Germ Cells in Culture
Primordial germ cells (PGCs) are highly specialized cell population that arises from the epiblast in vivo. There are three critical steps in the life cycle of these cells: 1-Specification 2-migration and proliferation 3-prenatal and postnatal sex specific development. Specification of germ cells in epiblast occurs due to signals secreted from extraembryonic tissues. Primordial germ cells are re...
متن کاملایجاد یک روش نوین آزمایشگاهی الایزا توبی (ToBi Assay) برای تعیین پوتنسی واکسن بومی توکسوییدی کزاز درایران
Background: One of the major uses of large number of laboratory animals in manufacturing the vaccines is the quality control testing of vaccines, particularly potency testing of vaccines containing the tetanus toxoids by either lethal challenge or serum neutralization tests. Recently, because of various difficulties to obtain quality laboratory animals and in adequate environmental conditions, ...
متن کاملP-120: Meiotic Spindle Visualization and Zona Pellucida Birefringence in Relation to Morphology of In Vivo and In Vitro Matured Human Oocytes of In Vivo and In Vitro Matured Human Oocytesof In Vivo and In Vitro Matured Human Oocytes
Background: The meiotic spindle plays an important role in the oocyte during chromosome alignment and separation at meiosis. The zona pellucid (ZP) is a dynamic matrix composed of filaments with the properties that might reflect the history of oocyte cytoplasmic maturation. Since, spindle and ZP in living oocytes are highly birefringent, their structures can be viewed noninvasively by using a P...
متن کاملA Feasible Solution to Distinguish the Transformer Winding Deformation from Insulation Characteristic Impacts on FRA Spectrum
Frequency Response Analysis (FRA) is popular technique which has been used since the last decade as a diagnostic method for transformers. However, accurate interpretation of FRA measurements is still challenging. Recent studies reveal that apart from winding deformation, FRA data can also be influenced by moisture variation in transformer paper insulation. Hence, a specific transformer’s model ...
متن کاملNovel Approach of Differential Staining to Detect Necrotic Cells in Preimplantation Embryos
Background This novel approach describes a rapid and simple method for identification of necrotic vs. viable cells within a mammalian blastocyst. MaterialsAndMethods Hatched bovine blastocysts produced in vitro were first incubated for 30 min in pre-equilibrated culture medium containing propidium iodide (PI; 300μg/ml) and bisbenzimide (Hoechst: H33342; 5μg/ml) fluorescent dyes. Embryos were th...
