1 The research reported here was supported in part by a grant from the Health Research Council of the city of New York (U-1008). 2 Recipient of an NIH Postgraduate address: Cell Research Laboratory, Mt. Sinai School of Medicine of the City University of New York, New York 10029 The light microscopical studies of Ross (21) and Bodenstein (6) have shown that the salivary gland imaginal disc becomes visible during the second larval instar as a small band of cells intercalated between the gland and the duct. During the first larval instar the gland consists only of larval salivary gland cells and duct cells (6, 21).

N2 - The fine structure of first, second, and third larval instar salivary glands is described. The salivary glands of first instar larvae consist of larval cells and duct cells; however, there is an abundance of microtubules in the cells surrounding the duct junction which distinguishes them from the more proximal duct cells. Second larval instar salivary glands consist of larval salivary gland cells, duct cells, and, in addition, the cells surrounding the duct junction are filled with microtubules, and there are dividing cells surrounding the duct. Third larval instar salivary glands contain larval cells, duct cells, and imaginal disc cells which are characterized by the abundance of microtubules and ribosomes, and the presence of centrioles. It is proposed that the cells surrounding the duct junction in the first larval instar are the precursors of the imaginal disc cells.
