title: Reprogramming and DNA synthesis in Galleria mellonella larval epidermal cells.
abstract: Epidermal cells from ligated day-3 last instar larvae of Galleria mellonella secrete a larval cuticle if exposed to ecdysone immediately following ligation; whereas, they deposit a pupal cuticle if exposed to ecdysone three to four days after ligation. During the period of reprogramming the genome in the diploid cells of the wax moth larvae no DNA synthesis occurs. This is direct proof that DNA synthesis is not required for reprogramming in the epidermis of Galleria during larval-pupal transformation.
