Technical note: viability and motility of vitrified/thawed primordial germ cell isolated from common carp (Cyprinus carpio) somite embryos.
The feasibility of cryopreserving common carp (Cyprinus carpio) primordial germ cells (PGC) by vitrification of whole embryos at the 22- to 28-somite stage was investigated. Green fluorescent protein (GFP)-labeled PGC were cooled rapidly using liquid nitrogen after exposure to a pretreatment solution containing 1.5 M cryoprotectant (ethylene glycol or dimethyl sulfoxide, 30 or 50 min) and a vit...
متن کاملThe differentiation of germ cells and gonads during development of carp (Cyprinus carpio L.). A study with anti-carp sperm monoclonal antibodies.
Gonadal development, germ cell differentiation and the appearance of membrane antigenic determinants, specific for male and female germ cells during gonadogenesis, was studied in larval and juvenile carp (Cyprinus carpio L.) until 25 weeks after fertilization. Indirect immunofluorescence studies with four monoclonal antibodies raised against carp spermatozoa revealed that monoclonal antibody WC...
متن کاملReview 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 کاملThe 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 (...
متن کاملI-18: Avian Chimeras and Germ Cell Migration
Background: In avian species, the germ line stem cell population arises outside of the embryonic gonad and proceeds on a circuitous migration to the germinal epithelium. Specifically, in the avian embryo, the process of germ line stem cell migration proceeds through a series of active and passive migratory phases. The germline stem cells or primordial germ cells (PGCs) located in the epiblast o...
