Abstract
Honeybees are among the most important pollinators in nature, and honeybee-associated products are useful in various areas, including the food industry. However, honeybees may be infected by various types of pathogens. The study of honeybee-associated diseases would greatly benefit from a successful cell culture system, but although some honeybee cell culture techniques have been introduced, these methods have not yet been fully established. Here, we describe a primary cell culture method for the honeybee, Apis mellifera. We isolated, sterilized, and seeded egg cells into non-coated cell culture dishes to generate cell aggregates. After approximately 10 d, aggregates were dissociated and seeded to cell culture dishes. Cell passages were continuously performed, with sub-culturing every 3–4 d. The cells expressed non-adherent phenotypes. Their growth increased with the passage number when they were cultured in growth medium based on L-15 insect medium but not Schneider’s insect medium. Finally, polymerase chain reaction confirmed that the cells originated from A. mellifera. Our results suggest that the culturing methods described herein are appropriate for isolating primary cells from honeybee eggs. These methods could thus facilitate the study of honeybee-associated pathogenesis, development, and toxicology.
