M. Rezaul Karim¹, Keita Endo², Adrian W Moore³, Hiroaki Taniguchi¹

¹Laboratory for Genetic Code, Graduate School of Life and Medical Sciences, Doshisha University, ²Laboratory for Circuit Mechanisms of Sensory Perception, RIKEN Brain Science Institute, ³Disease Mechanism Research Core, RIKEN Brain Science Institute

Herein we describe the process of whole mount immunostaining of Drosophila antennae, which enables us to better understand the molecular mechanisms involved in the diversification of olfactory receptor neurons (ORN)s.

Herein we describe a procedure to capture live images of Drosophila gastrulation. This has enabled us to better understand the apical constriction involved in early development and further analyze mechanisms governing cellular movements during tissue structure modification.

Biochemistry

A Protein Preparation Method for the High-throughput Identification of Proteins Interacting with a Nuclear Cofactor Using LC-MS/MS Analysis

Megumi Tsuchiya^*1, M. Rezaul Karim^*2, Taro Matsumoto³, Hidesato Ogawa¹, Hiroaki Taniguchi^3,4,5

We have established a method for the purification of coregulatory interaction proteins using the LC-MS/MS system.

Biochemistry

Manipulating Living Cells to Construct Stable 3D Cellular Assembly Without Artificial Scaffold

Takehiro Yamazaki^*1, Hiroaki Taniguchi^*2, Shoto Tsuji¹, Shiho Sato¹, Takahiro Kenmotsu¹, Kenichi Yoshikawa¹, Koichiro Sadakane¹

¹Faculty of Life and Medical Sciences, Doshisha University, ²The Institute of Genetics and Animal Breeding, Polish Academy of Sciences

We demonstrate a novel method for constructing a single-cell-based 3-dimensional (3D) assembly without an artificial scaffold.

Neurogenesis Using P19 Embryonal Carcinoma Cells

Paweł Leszczyński¹, Magdalena Śmiech¹, Aamir S. Teeli¹, Aleksandra Zołocińska², Anna Słysz², Zygmunt Pojda², Mariusz Pierzchała³, Hiroaki Taniguchi¹

¹Department of Experimental Embryology, Institute of Genetics and Animal Breeding, Polish Academy of Sciences, ²Department of Regenerative Medicine, Maria Skłodowska-Curie Institute - Oncology Center, ³Department of Genomics and Biodiversities, Institute of Genetics and Animal Breeding, Polish Academy of Sciences

The P19 mouse embryonic carcinoma cell line (P19 cell line) is widely used for studying the molecular mechanism of neurogenesis with great simplification compared to in vivo analysis. Here, we present a protocol for retinoic acid-induced neurogenesis in the P19 cell line.
