ORBi Open Repository and Bibliography
In may 2007, the ULg's Administrative Board (joined in June 2007 by the FUSAGx) decided to create an institutional repository and defined a strong institutional self-archiving policy to increase the visibility, accessibility and impact of the University's publications (Board's decision).
This decision led to the official launch, in November 2008, of the ORBi platform including both the Academic Bibliography and the Institutional Repository of the Wallonia-Europe University Academy.

A method allowing long term culture and expansion of chicken primordial germ cells - Tonus, Céline; Waroux, Olivier; Grobet, Luc
We developed an original method allowing long term culture (up to 20 month) of undifferentiated chicken PGCs, with good proliferation rates. We use a co-culture system: PGCs are cultivated in cell culture inserts, in the presence of irradiated Buffalo Rat Liver cells. According to our own experience, physical separation of PGCs and feeder cells limits the differentiation of PGCs. Our PGCs lines keep their original phenotype including their gonadal colonization ability. We also developed a novel cryopreservation method based on vitrification, in complement of a slow rate freezing.
