Studies on Insect Growth Regulating Substances with Insect Cell Cultures [PDF]

open access: yesAgricultural and Biological Chemistry, 1985
The sensitivity of cultured insect cells to a moulting hormone depended on their origin. Cell proliferation of cell-line C6/36, which originated from an Aedes albopictus larva, was suppressed by high concentrations of 20-hydroxyecdysone but was greatly promoted by low concentrations.
