53Department of Applied Biology“Self-recycling” and its application in hair science Self-recycling is said to refer to the use of the tissues and biological substances in your body as raw materials and their transformation into useful processed goods. In my lab, we use hair and nail clippings that are generated as waste in daily life as a first step. We are currently pursuing development projects in the area of hair care, and several companies have started to make use of our findings.Professor Fujii's areas of research include self-recycling, the development of biomaterials, protein engineering, and biopolymers. He is a member of the Japanese Cosmetic Science Society, the Society of Fiber Science and Technology Japan, the Japanese Biochemical Society, the Society of Polymer Science Japan, and the Pharmaceutical Society of Japan. His areas of expertise include biochemistry, neuroscience, protein science, and history.This is an imagined conversation between students 50 years in the future.Student A: Fifty years ago, when you had your hair cut at a salon or barber shop, they threw the cut hair away!Student B: No, really? What a waste! It is such a valuable resource. In the past, they didn't have the technology to process and reuse it.Outlook for researchGraduates are employed by such organizations as Shiseido, LION, Menicon, Asahi Kasei, Unicharm, Otsuka Pharmaceutical, Hisamitsu, Toray Industries, Toyobo, Seiko Epson, Murata Manufacturing, Dokkyo Medical University, Shinshu University, and Nagano Prefecture.Outlook for students after graduationA study group aims to achieve a score of 700 on the TOEIC test.We announced and promoted keratin lm at Cosmetics Japan, an international cosmetics trade show held at Tokyo Big Sight.Toshihiro FujiiProfessorDepartment of Applied BiologyUsing micromanipulation to study the mechanism of fertilization and preserve, regenerate, and utilize genetic resourcesMy lab studies physiological aspects of early events during fertilization in mammals as well as technical innovations involving the preservation and utilization of genetic resources. My students and I have published more than 100 research papers so far describing our research into haploid gametes (spermatozoa and oocytes) and diploid embryos from various mammalian species, including mice, rats, rabbits, cats, horses, buffalo, cattle, whales, and humans.Professor Hochi took his current position in 2008 after working as a researcher (1986 to 1992) at Snow Brand Milk Products Co. Ltd., as a visiting assistant professor (1992 to 1995) and visiting associate professor (1995 to 1996) at Obihiro University of Agriculture and Veterinary Medicine, and as an assistant professor (1996 to 1999) and associate professor (1999 to 2008) in the Faculty of Textile Science and Technology at Shinshu University. He is engaged in research on reproductive physiology, cryobiology, and developmental engineering in small experimental rodents, large domestic animals, and humans.Advanced reproductive technologies such as intracytoplasmic sperm injection and somatic cell nuclear transplantation made it possible to bring the mammoth back to life. Furthermore, we have recently established pluripotent stem cell lines in laboratory rats. If these ES or iPS cells could be dierentiated into functional gametes, the process would be the ultimate treatment for infertility.Outlook for researchGraduates are employed by pharmaceutical and food-related companies as well as national and local organizations (as public ocials). In what has become a recent trend, some skilled graduates work at human infertility clinics as potential embryologists.Outlook for students after graduationIntracytoplasmic injection of shhook-shaped rat sperm heads was dicult to achieve, but several clues helped us expand its application to freeze-dried spermatozoa.Micromanipulation enables us to handle not only oocytes with diameters of 100 to 120 μm, but also much smaller sperm cells.A microtubule network can be assembled from a centrosome of spermatozoon immediately after fertilization.Shinichi HochiProfessor
