| Outline of Final Research Achievements |
In this study, I aimed to analyze the pattern formation between the induction of whisker follicles and somatosensory nerves through development of organ culture methods in order to observe the formation of a key structure, called Merkel cell-neurite complex, on a dish. I first analyzed the complex between whisker follicles and trigeminal nerves using immunohistochemical techniques. I initially developed two distinct culture methods of a whisker pad and a trigeminal ganglion explant, and then combined them. After the co-cultivation of the whisker row with a trigeminal ganglion explant, a Merkel cell-neurite complex composed of Merkel cells, trigeminal nerve fibers and Schwann cells was observed. My method for the formation of a Merkel cell-neurite complex in an organ culture will contribute to understanding the regulatory mechanisms of the coordination between trigeminal nerves and whisker follicles.
