Japanese common newts (Cynops pyrrhogaster) have high ability to regenerate their injured organs including neural tissues, for example, the neural retina belonging to central nervous system. We attempted to clarify the molecular mechanism underlying the formation of a neural network during newt retina regeneration, and focused on the microtubule dynamics(More)
Advances in biology have clarified the details of many phenomena and their results have been applied to many fields. However, in these fields, applications require dexterous and skillful manipulation. Hence, realizing high productivity is still difficult. To solve this problem, assisted cell manipulation and automated systems have been researched and(More)
— In this paper, we presented a design for an automated cell supply system that can be used with complex microfluidic applications requiring single cell loading such as the current nuclear transplantation method. The aim of the system is to automatically transfer mammalian donor (∼15µm) or egg (∼100µm) cells one by one from a container to a PDMS(More)
In this paper, we propose a sensor for detecting particles flowing in a micro channel fabricated with polydimethylsiloxane (PDMS) chip. A light source placed at one side of a micro channel irradiates the micro channel through plastic optical fibers (POF), and a detector placed at the opposite side of the micro channel receives light transmitted through the(More)
