This invention discloses a drug-resistant Ewing sarcoma cell line, named human Ewing sarcoma cell ES 003, which was deposited at the China Center for Type Culture Collection on March 10, 2026, with accession number CCTCC NO: C202642. The cell line exhibits doxorubicin resistance; specifically, doxorubicin has an IC50 of [missing information - likely referring to an IC50 value] against the human Ewing sarcoma cell ES 003. 50 Above 5μM.

The application belongs to the technical field of plant cultivation and particularly relates to a Blumea riparia growth medium, a tissue culture medium, a tissue culture method and application. The Blumea riparia growth medium takes MS medium as a basic medium and further comprises 0.2-0.3 mg / L NAA, 0.08-0.16 mg / L DA-6, 10 mg / L vitamin C, 20 mg / L myo-inositol, 30 g / L sucrose and 6 g / L agar. DA-6 and NAA are jointly applied to improve the rooting efficiency, root length and plant height of Blumea riparia. The Blumea riparia germplasm with high content of levorotatory borneol is used as an explant to carry out tissue culture and seedling raising, the Blumea riparia tissue culture seedling has high content of levorotatory borneol, and Blumea riparia stable genetic good seedlings can be produced.
