abm | Immortalized Drosophila Embryonic Cells (R3) | T0702

UAS-Ras^V12 embryos. The Ras^V12 immortalized cell lines have significantly up-regulated cell-cycle and cell-division gene expression including gene targets of the E2 promoter binding factor/retinoblastoma protein (E2F/RB) pathway. Specifically, R3 express upregulated Cyc A, tum, sti, pav, stg, and dup. The cell lines are in a proliferative undifferentiated progenitor-like state associated with increasing levels of Polycomb Group (PcG) transcripts during the immortalization process. Related to adult muscle precursors (AMPs), a stem cell-like population contributing to adult muscles and sharing properties with vertebrate satellite cells, the immortalized R3 cell line retained the capacity for myogenic differentiation when treated with the steroid hormone ecdysone. The cell line is recommended as a tool for Drosophila embryogenesis and muscle cell differentiation and proliferation.

The base medium for this cell line is Schneider's Insect Medium (TM034). To make the completed growth medium, add the following components to the base medium: heat-inactivated fetal bovine serum to a final concentration of 10%, and Penicillin/Streptomycin Solution to a final concentration of 1%.
Carbon dioxide (CO₂): 5%, Temperature: 22.0°C.
abm does not recommend to use heat-inactivated FBS for cell culture unless specified otherwise.

Quality Control:

(1) Inducing muscle cell differentiation by treating cells with ecdysone and perform immunofluorescence staining and qPCR to assess the upregulated expression of mhc and Tropomyosin (Tm).

(2) Up-regulated genes in DPCs are analyzed by DAVID (the Database for Annotation, Visualization and Integrated Discovery).
