Immortalized Drosophila adult muscle progenitor-like cells that can be differentiated in vitro upon ecdysone treatment.
These cell lines were derived from Drosophila embryonic primary cultures established from Act5C > UAS-RasV12, UAS-GFP embryos in which ubiquitously-expressed Gal4 drives the expression of both RasV12 and GFP (as described in Simcox et al., 2008). Although the cultures were prepared from whole embryos, the cell lines present many characteristics of Adult Muscle Progenitor cells (often compared to vertebrate muscle stem cells, or satellite cells). First, they express a number of genes usually expressed in AMPs (e.g., twist). Second, upon addition of the steroid hormone ecdysone, the cells can be differentiated into muscle cells, expressing terminal differentiation markers (e.g., myosin heavy chain) as described in Dequeant et al., 2015 with the R1 cell line being the most efficiently differentiated cell line into muscle cells.
