In Vivo Two-photon Imaging of Cortical Neurons in Neonatal Mice Hidenobu Mizuno1,2,3, Shingo Nakazawa2,3, Takuji Iwasato2,3 1International Research Center for Medical Sciences (IRCMS), Kumamoto University, 2Division of Neurogenetics, National Institute of Genetics, 3Department of Genetics, SOKENDAI (The Graduate University for Advanced Studies) We present an in vivo two-photon imaging protocol for imaging the cerebral cortex of neonatal mice. This method is suitable for analyzing the developmental dynamics of cortical neurons, the molecular mechanisms that control the neuronal dynamics, and the changes in neuronal dynamics in disease models.
Perfusable Vascular Network with a Tissue Model in a Microfluidic Device Yuji Nashimoto1, Yukako Teraoka1, Ramin Banan Sadeghian1, Akiko Nakamasu2, Yuichiro Arima3, Sanshiro Hanada3, Hidetoshi Kotera1, Koichi Nishiyama3, Takashi Miura2, Ryuji Yokokawa1 1Department of Micro Engineering, Kyoto University, 2Graduate School of Medical Sciences, Kyushu University, 3International Research Center for Medical Sciences (IRCMS), Kumamoto University The protocol describes how to engineer a perfusable vascular network in a spheroid. The spheroid's surrounding microenvironment is devised to induce angiogenesis and connect the spheroid to the microchannels in a microfluidic device. The method allows the perfusion of the spheroid, which is a long-awaited technique in three-dimensional cultures.
