The application relates to the technical field of biology, and discloses a method for inducing a cell line of immortalized musk deer scent glands to synthesize dihydrotestosterone, wherein the cell line is obtained by transfecting a primary musk deer scent gland epithelial cell with a lentivirus carrying an SV40 Large T antigen and performing resistance screening; the cell line is in an epithelial cell form and stably expresses keratin 18, cholesterol side chain cleavage enzyme, 17 alpha-hydroxylase and 3 beta-hydroxysteroid dehydrogenase. Through lentivirus-mediated SV40 Large T antigen transfection, the primary musk deer scent gland epithelial cell breaks through the limit of replicative senescence and obtains unlimited proliferation capacity, effectively overcomes the defects that the primary cell is prone to fibrosis and rapidly loses metabolic function during in-vitro culture, provides a standardized cell model with a clear genetic background and persistent metabolic activity for biological manufacturing of dihydrotestosterone, and relieves the dependence on endangered animal live resources.
