Am. Vogel et T. Gerster, EXPRESSION OF A ZEBRAFISH CATHEPSIN-L GENE IN ANTERIOR MESENDODERM AND HATCHING GLAND, Development, genes and evolution, 206(7), 1997, pp. 477-479
During a differential display-based screen for developmentally regulat
ed genes in zebrafish, we have isolated a cDNA for zebrafish cathepsin
L. termed cart. The gene shows abundant expression in the anteriormos
t cells of the head process which give rise to the polster and later t
o the hatching gland. Expression of catL persists in these tissues unt
il hatching. carL thus provides a useful marker for very anterior mese
ndodermal structures in zebrafish.
