Animals
C57BL/6NJcl and 129X1/SvJJmsSlc mice were purchased from CLEA Japan and Japan SLC, respectively. A transgenic mouse line harboring GFP under an Oct4 promoter (GOF-Tg; Ohbo et al., 2003) was provided by RIKEN BioResource Center (BRC) to CDB, and has been maintained in homozygous state under C57BL/6 background in CDB animal facility. A transgenic mouse line harboring GFP under a CAG promoter (CAG-GFP Tg; Okabe et al., 1997) was provided to CDB by Masaru Okabe at Osaka University, and has been maintained in homozygous state under C57BL/6 background in CDB animal facility. Animals were housed in environmentally controlled rooms, and animal experiments were conducted under the institutional guidelines for Animal and Recombinant DNA Experiments that are consistent with ARRIVE guidelines. The experiments were approved by Institutional Animal Care and Use Committee of RIKEN Kobe Branch (Permit No., AH26-01).
