**Figure 1. miR-34a expression in CD44 populations.** Access the [full size image][1] and [R script][2] used to generate this figure. Illustrates (**A**) the percent expression of let-7b or miR-34a (normalized to miR-103) relative to CD44- cells as well as (**B**) relative expression levels of let-7b or miR-34a (normalized to miR-103) are presented for CD44+ and CD44- populations. Expression levels were made relative to let-7b in CD44- cells which were assigned a value of 1. This is the same experiment as part A, which is from one biological repeat. Additional details for this experiment can be found at https://osf.io/tkn6c/. **Figure 1 - figure supplement 1. Flow cytometry gating strategy and controls.** Access the [full size image][1] and [.svg file][2] used to generate this figure. This figure includes (**A**) Representative density plots of gating strategy to identify CD44+ and CD44- populations from LAPC4 cells purified from xenograft tumors and (**B**) Single parameter histogram for CD44 using human peripheral blood mononuclear cells (PBMC) previously gated on single cell population.
