Research Abstract

1. Targeting vector was designed to integrate EGFP in erythropoietin(EPO) gene. EGFP-IRES-puroR gene was knocked-in into the start codon of EPO gene. This vector was electroprated into C57BL/6 derived ES cells and then EPO-EGFP ES cells were established. These ES cells were cultured in various condition such as ectoderm, mesoderm and endoderm and EGFP was evaluated by FACS.
2. EPO-EGFP ES cells were injected into mouse blastcyst and then EPO-EGFP+/-mouse was established. Section of kidney from EPO-EGFP+/-was analyzed by fluorescent microscopy. Isolated cells from EPO-EGFP+/-mouse were analyzed by FACS.
