Social
Professional and Outreach Activities
A peptide hormone, Cubifrin, inducing gamete maturation and spawning of Japanese common sea cucumber was found from nerve tissues, and currently provided as a potent spawning-inducing reagent of Apostichopus japonicus form the TLO of Kyushu University. As a social action program of our laboratory, we have been operating workshop and guidance of the egg-laying techinique with use of Cubifrin..
