| Outline of Final Research Achievements |
I analyzed wound healing and regeneration initiation after tail amputation using Xenopus tadpoles.
1. Analysis of notochord fragments grafted under host skin suggested that wounding of notochord, skin and muscle tissue is necessary to initiate notochord regeneration.
2. I established transgenic lines harboring egfp under control of xes1 promoter/enhancer, in which wound epidermis is labeled in situ. Pharmacological analysis using the transgenic tadpoles showed that TGF-β, ROS and ERK signals are required for both es1 expression and proper wound healing.
