Establishment of two cell lines from embryonic tissue of the tobacco hornworm,Manduca sexta (L.)

Abstract
Two cell lines were derived from primary cultures of embryonic tissue of the tobacco hornworm,Manduca sexta (L.). The cell lines were maintained on hemolymph-free synthetic insect medium. Cytogenetic and immunological identification of the lines were carried out. Techniques for obtaining the line and medium, subculturing and freezing procedures for long-term storage, and the morphological and growth characteristics are described.
