New insights into limb formation
September 7th, 2009
Investigators at Burnham Institute for Medical Research (Burnham) and the University of Connecticut Health Center (U.C.H.C.) have gained new understanding of the role hyaluronic acid (HA) plays in skeletal growth, chondrocyte maturation and joint formation in developing limbs. Significantly, these discoveries were made using a novel mouse model in which the production of HA is blocked in a tissue-specific manner. The Yamaguchi laboratory genetically modified the Has2 gene, which is a critical enzyme for HA synthesis, so that the gene can be "conditionally" disrupted in mice. This is the first time a conditional Has2 knockout mouse has been created, a breakthrough that opens vast...
