| Outline of Final Research Achievements |
Transcription factor Pax2 is essential for kidney development. We have generated embryonic stem (ES) cell lines that repress Pax2 expression and examined their differentiation potential by embryoid body (EB) formation. EBs were cultured with or without retinoic acid and activin A. EBs were analyzed by reverse transcription (RT)-PCR and immunocytochemical analysis. Aquaporin-1 (Aqp1) and integrin 8 were upregulated when cells were induced to form EBs. With retinoic acid and activin A, EBs overexpressed Pax2-induced Pax8, BMP4, BMP7, and Podocin. ES cells that expressed aquaporin-1 and Pax2 incresed by analysis of the FACS cell sorting. ES cell lines with inducible Pax2 expression may be useful for dissecting genetic cascades functioning in the development of various organs, including the kidney.
