Abstract
We have established trophoblast cell lines, from parthenogenesis-derived buffalo blastocysts. The buffalo trophoblast cells were cultured continuously over 200 days and 21 passages. These cells were observed by phase-contrast microscopy for their morphology and characterized by reverse transcriptase polymerase chain reaction and immunofluorescence against trophoblast-specific markers and cytoskeletal proteins. Trophoblast cells showed positive staining for CDX2, a marker of these cells at both blastocyst and cell line levels. Epithelial morphology of these cells was revealed by positive staining against cytokeratins and tubulin but not against vimentin and dolichos biflorus agglutinin. Gene expression profiles of many important placenta-specific genes were studied in the primary trophectoderm outgrowths, which were collected on days 0, 5, 9, 12 and 15 of culture and trophoblast cell line at passages 12-15. Therefore, the trophoblast cell line derived can potentially be used for in vitro studies on buffalo embryonic development.
期刊介绍：
An international journal dedicated to the rapid publication of original research in early embryology, Zygote covers interdisciplinary studies on gametogenesis through fertilization to gastrulation in animals and humans. The scope has been expanded to include clinical papers, molecular and developmental genetics. The editors will favour work describing fundamental processes in the cellular and molecular mechanisms of animal development, and, in particular, the identification of unifying principles in biology. Nonetheless, new technologies, review articles, debates and letters will become a prominent feature.
