Article Title: Small Molecule Screening with Laser Cytometry Can Be Used to Identify Pro-Survival Molecules in Human Embryonic Stem Cells
doi: 10.1371/journal.pone.0054948
Figure Lengend Snippet: Three treatments are compared to assess changes in survival of dissociated hESCs: 0.1% DMSO (negative control; A,D ), 10 µM HA-1077 (positive control; B,E ), and 10 µM AST 5588603 (representative of small molecules identified in OCT4-GFP screening assay; C,F ). A-C: Readout from the Acumen microplate cytometer. The wells treated with HA-1077 and AST 5588603 had similar numbers of GFP positive objects (quantified in G ). D-F: Alkaline phosphatase staining of cells treated as described. Pluripotent cells are stained with a red color. Wells treated with HA-1077 ( E ) contain significantly more pluripotent cells than cells treated with DMSO or any other candidate compounds. G: Quantification of GFP signal detected in ( A- C). H: Quantification of alkaline phosphatase staining in ( D-F ) by calculating what percent of the well area stained positive for alkaline phosphatase. Data shown as mean ±SD, ***: p<0.001.
Article Snippet: In all cases, data were acquired using an Acumen microplate cytometer (TTP Labtech).
