Continuous muscle, glial, epithelial, neuronal, and hemocyte cell lines for Drosophila research
Figures

Morphology of cells.
(A–C) Glial-lineage clones. The cells have an elongated morphology with variable lengths from approximately 20 to >50 µm (red arrowheads). (D–F) Tracheal-lineage cells. Btl3 and Btl7 cells form squamous epithelial sheets. Btl8 are closely associated but do not abut each other to form a sheet. (G–J) Mesodermal-lineage cells. The cells have a bipolar morphology. Multinucleate cells are frequently found in 24BGI-F3 and 24BG1-GI clones (red arrowheads). (K, L) Neuronal-like clones. ActGSB-6 cells are mainly bipolar; however, some have asymmetric processes or thin processes (red arrowheads). ActGSI-2 are bipolar. (M) Hemocyte-like clone ActGSI-3. The cells form floating clusters that increase in cell number as they proliferate. Individual cells have a round morphology. (N) Schneider’s S2 cells. The cells are thought to be of hemocyte type and grow as single round cells in suspension. Scale bar = 10 µm.

Expression levels of ligands and receptors for major signaling pathways.
The ligand and receptor annotation for major signaling pathways was obtained from FlyPhoneDB (https://www.flyrnai.org/tools/fly_phone/web/). The expression levels of ligands and receptors are represented as a heatmap of FPKM values.

Comparison of lineage-restricted Ras cell lines with previously isolated Drosophila cell lines.
RNAseq data for the cells described in this work were compared with RNAseq datasets determined previously for 24 other Drosophila cell lines (Cherbas et al., 2011) by clustering analysis using Pearson correlation coefficient scores. A matrix of Pearson correlation scores shown. On the heatmap key (right-hand side), a value of 1 indicates complete correlation; 0 indicates no correlation; −1 indicates complete anti-correlation.

Principal component analysis (PCA) of RNAseq data from the lineage-restricted Ras cell lines.
The RNAseq datasets for all cell lines were aligned to the Drosophila genome (r6.48) using STAR. The PCA plot was generated using heatmaply. As expected, cells derived using the same GAL4 driver tend to cluster with one another.

Relative expression of transcription factors associated in the literature with specific tissue lineages in the lineage-restricted Ras cell lines.
The set of tissue-specific transcription factors were selected manually from the literature. The fold change in gene expression levels for each cell line as compared to all other cell lines derived using different drivers were calculated using DESeq2 and fold change values are visualized on the heatmap.

Analysis using the Drosophila RNAi Screening Center’s single-cell DataBase (DRscDB), all datasets used are from FCA 10x Sequencing (https://flycellatlas.org/). The in situ data were from the BDGP (https://insitu.fruitfly.org/cgi-bin/ex/insitu.pl) and the enrichment p value was calculated by a hypergeometric test.

Primary cultures and continuous lines produced from indicated genotypes.
Glial primary cultures grew well at first and could be passaged several times; however, only one continuous line was produced. This line was cloned using single-cell dilution to produce three clonal derivatives. Tracheal lines were produced readily. Cloning the parental lines was not successful with either single-cell dilution or puro selection. Mesodermal lines were produced using expression of RasV12 with 24B-Gal4 but not Mef2-Gal4. Cloning of the continuous lines was done using single-cell dilution. Neuronal. Expression of RasV12 with neuronal Gal4 drivers (elav-Gal4 or scratch-Gal4) did not give rise to continuous lines. Cloning of lines generated by broad expression of RasV12 with Act5C-GeneSwitch-Gal4 produced two clonal lines with neuronal characteristics and one with hemocyte characteristics. These were cloned using puro selection.

Analysis of marker gene expression in parental lines and clones.
Cell lines and their clonal derivatives were stained with antibodies against the indicated markers. The fraction of cells staining positive was determined. The intensity and cellular location of the signal are indicated in cases when there was variation. The clones and parental lines highlighted were analyzed by RNAseq.
