Homeodomain-containing transcription factors are essential for a variety of
processes in vertebrate development, including organogenesis. They have be
en shown to regulate cell proliferation, pattern segmental identity and det
ermine cell fate decisions during embryogenesis. During nephrogenesis, home
obox genes play an important role at multiple developmental stages, from th
e early events in intermediate mesoderm to terminal differentiation of glom
erular and tubular epithelia. Increasingly sophisticated genetic approaches
will probably reveal additional functions for this class of transcription
factors in the developing kidney and lead to the identification of critical
downstream target genes. Curr Opin Nephrol Hypertens 9:37-42. (C) 2000 Lip
