| Outline of Final Research Achievements |
In the present study, to begin to understand these mechanisms, we investigated the role of Mash1-positive cells in regulating adult taste bud cell differentiation through the loss of Mash1-positive cells using the Cre-loxP system. We found that the cells expressing type III cell markers; aromatic L-amino acid decarboxylase (AADC), carbonic anhydrase 4 (CA4), glutamate decarboxylase 67 (GAD67), neural cell adhesion molecule (NCAM), and synaptosomal-associated protein 25 (SNAP25); were significantly reduced in the circumvallate taste buds after administration of tamoxifen. However gustducin and Phospholipase C beta2 (PLC beta2);markers of type II taste bud cells; were not significantly changed in the circumvallate taste buds after administration of tamoxifen. These results suggest that Mash1-positive cells could be differentiated to the type III cells, not to the type II cells in the taste bud.
