| Outline of Final Research Achievements |
Heparin affinity growth factor group is expected as one of therapeutic targets for neurodegenerative diseases typified by hepatocyte growth factor (HGF), but there are many problems to be solved to realize clinical application. In this study, we aim to develop an adult neurogenesis control method by targeting heparan sulfate proteoglycan (HSPG) in the extracellular matrix and optimizing GF activity localization and "signal crosstalk" with other heparin affinity growth factors. Modification of sugar chain was considered important for preparation of heparin affinity growth factor / heparan sulfate chain typified by FGF - 2 which controls adult neurogenesis. We proceeded with disaccharide analysis using samples of the adventitial neurogenic region, the subventricular zone and the hippocampus, and showed characteristics of sugar chain modification such as sulfation.
