Feeder-free human embryonic stem cell (hESC) culture is associated with the presence of mesenchymal-like cells appearing at the periphery of the colonies. The aim of this study was to identify this early differentiation process. Long-term feeder-free hESC cultures using matrigel and conditioned medium from mouse and from human origin revealed that the(More)
Primary leptomeningeal oligodendroglioma occurs very rarely and in only one patient a deletion of chromosome 1p has been reported. We describe a 60-year-old man with a prior history of an epileptic seizure three years earlier, who was referred because of depression and a rapid evolving cognitive impairment. Brain MRI showed a diffuse right parieto-occipital(More)
AIMS/HYPOTHESIS Upregulation of the functional beta cell mass is required to match the physiological demands of mother and fetus during pregnancy. This increase is dependent on placental lactogens (PLs) and prolactin receptors, but the mechanisms underlying these events are only partially understood. We studied the mRNA expression profile of mouse islets(More)
AIMS/HYPOTHESIS Pregnancy requires an increase in the functional beta cell mass to match metabolic needs for insulin. To understand this adaptation at the molecular level, we undertook a time course analysis of mRNA expression in mice. METHODS Total RNA extracted from C57Bl6/J mouse islets every 3 days during pregnancy was hybridised on commercially(More)
