Intestinal microbiota and human health

submitted by: COMED2010
The central objective of the MetaHit project is to establish associations between the genes of the human intestinal microbiota and human health and disease. The research work is focused on two disorders of increasing importance in Europe, Inflamatory Bowel Disease (IBD) and obesity. First, we need to establish an extensive reference catalog of microbial genes and genomes present in the human intestine. The second challenge is to develop tools to determine which genes and genomes of the...

Role of the Neural Crest in Vertebrate Development and Evolution - Part 2: The Role of the Neural Crest in Head Development and in Vertebrate Evolution (30:04)

submitted by: video_collector
Nicole Le Douarin shares her research on the role of the neural crest in skeletal development. The Q/C (quail/chick) marker system revealed that apart from the peripheral nervous system (PNS), the melanocytes and some endocrine tissues, the NC plays a major role in the construction of the vertebrate head. The entire facial skeleton and part of the skull (frontal, squamosal, parietal bones) are of NC origin together with the connective tissues of the face and ventral part of the neck. The...
