Pax1 and Pax9 represent a subfamily of paired-box-containing genes. In vertebrates, Pax1 and Pax9 transcripts have been found specifically in mesodermal tissues and the pharyngeal endoderm. Pax1 expression in the sclerotomes has been shown to be indispensable for proper formation of the axial skeleton, but expression of Pax1 in the endoderm has not been studied in detail. We have cloned the chick homologue of the murine Pax9 gene. Our results show that transcripts of Pax1 and Pax9 are first… CONTINUE READING
