Detection of the Cell Proliferation Zone in Leaves by Using EdU
Authors:  Hokuto Nakayama, Kensuke Kawade, Hirokazu Tsukaya and Seisuke Kimura, date: 09/20/2015, view: 6340, Q&A: 0
Visualization of nuclei in S-phase cells in tissues is important for not only cell cycle research but also developmental research because morphogenesis is usually achieved by a combination of cell proliferation and cell expansion. Recently, DNA ...
