HOSTED BY OSA/SPIE Student Chapter at UCLA

Abstract:  Regenerative medicine deals with the process of replacing, engineering or regeneration human or animal cells, tissues or organs to restore or establish normal function. Before the invention of human Induced Pluripotent Stem Cells (iPS cells), embryonic stem cells (ES cells) were mainly used as a start point of research works in regenerative medicine. The ES cells are derived from the inner cell mass of a blastocyst, an early-stage preimplantation embryo. On the other hand, iPS cells can be induced from any human cells such as skin, iPS cleared ethical issues of regenerative medicine using ES cells. In results iPS cells accelerated research activities in regenerative medicine. The researchers often meet unintended cells among intended cells, here unintended cells are not the cells researchers want to get in their research. This is because there is not the perfect text book in regenerative medicine, yet. If the intended cells are floating cells, flow cytometry machine can remove the unintended cells and can move researchers to the next step. However, when the intended cells are adhesive cells, flow cytometry machine cannot remove the unintended cells.

Pinpoint Photonics, Inc. provides purification methods of cells by laser illumination which can be applied to adhesive cells. At the seminar the pain of researches in regenerative medicine will be explained and cell purification instrument is shown with experimental results.

Biography:   Koichiro Kishima is CEO of Pinpoint Photonics, Inc located in Kanagawa prefecture in Japan. Pinpoint Photonics, Inc is a company of imaging and laser technology which was established by him in 2018. He received BS and MS degrees in Mechanical engineering from Tokyo Institute of Technology in 1986 and 1988, respectively, and a PhD degree in Electrical Engineering from Tokyo Institute of Technology in 2012. He worked at Sony Corporation for 30 years. At Sony he was belonged to corporate research laboratories. He invented and patented a method of periodically polled domain structure of Lithium Niobate (PPLN). By the first demonstration of near field optical disc recording system, he was awarded Fujio Frontier Award from the Institute of Image Information and Television Engineering in 2001. He has 15 English journal papers and 70 US patents. From 2002 to 2003, he was a visiting researcher at Prof. Bahram Jalali laboratory in UCLA. At UCLA his research work was in the Silicon Photonics and the result was open on Applied Physics Letters Vol. 83, 4909 (2003).
