Marsupial mammals are born at a highly altricial state. Nonetheless, the neonate must be capable of considerable functional independence. Comparative studies have shown that in marsupials the morphogenesis of many structures critical to independent function are advanced relative to overall development. Many skeletal and muscular elements in the facial region show particular heterochrony. Becaus...

Unraveling the mechanisms underlying early neural differentiation of embryonic stem cells (ESCs) is crucial to developing cell-based therapies of neurodegenerative diseases. Neural fate acquisition is proposed to be controlled by a ‘default’ mechanism, for which the molecular regulation is not well understood. In this study, we investigated the functional roles of Mediator Med23 in pluripotency...

Previously, we have reported that glioblastoma (GBM) cells can be differentiated into cells showing neuronal, glial and non-neural (mesenchymal) phenotypes. Before the differentiation the GBM cells co-expressed GFAP, CD44, Beta III tubulin, MAP2, Vimentin, Nestin and SOX-2, whereas during the exposure to a neural differentiation medium the differentiation process was arrested at the early stage...

Neural stem cells (NSCs) are characterized by a capacity for self-renewal, differentiation into multiple neural lineages, all of which are considered to be promising components for neural regeneration. However, for cell-replacement therapies, it is essential to monitor the process of in vitro NSC differentiation and identify differentiated cell phenotypes. We report a real-time and label-free m...

Efficient in vitro differentiation into specific cell types is more important than ever after the breakthrough in nuclear reprogramming of somatic cells and its potential for disease modeling and drug screening. Key success factors for neuronal differentiation are the yield of desired neuronal marker expression, reproducibility, length, and cost. Three main neuronal differentiation approaches a...

The in vitro differentiation features of HPNE cells into neural cells were investigated. In this study, HPNE cells were pre-cultured in defined medium, and then induced by ITS treatment (insulin-transferrinselenium). After a transient ductal stage, HPNE cells present neural cell morphology. A series of neural markers were detected in terminally transformed HPNE cells. During HPNE transdifferent...

During embryogenesis the central and peripheral nervous systems arise from a neural precursor population, neurectoderm, formed during gastrulation. We demonstrate the differentiation of mouse embryonic stem cells to neurectoderm in culture, in a manner which recapitulates embryogenesis, with the sequential and homogeneous formation of primitive ectoderm, neural plate and neural tube. Formation ...
