Figure Lengend Snippet: (A) Experimental design to induce adipogenic differentiation of mdx FAP cell states. GM = growth medium; AIM = adipogenic induction medium; MM = maintenance medium. (B) and (C) Bar plots showing the percentage of ORO positive cells and PPAR-gamma positive cells per field. AM = adipogenic medium (AM = AIM + MM). n = 4. Statistical analysis was performed by a Two-way ANOVA. (D) Representative micrographs of (B) and (C). Cells were immunolabelled for PPAR-gamma (yellow) and nuclei were counterstained with Hoechst 33342 (blue). Lipid droplets were stained with ORO (red). (E) Experimental design applied to obtain fully differentiated adipocytes. (F) Bar plot indicating the percentage of ORO positive cells. n = 3. Statistical significance was calculated through a Student t-test. (G) Representative micrographs of (F). Lipid droplets in red (ORO staining) and nuclei in blue (Hoechst 33342). (H) Representative viSNE maps showing the expression of SCA-1 and phospho-CREB-1 assessed by mass cytometry in FAPs isolated from mdx mouse by MACS and cultured 72 hours either in GM or AIM. (I) Cluster 1 (in blue) and cluster 2 (in orange) obtained applying the FlowSOM algorithm and then mapped onto viSNE maps. (J) Plot representing the expression in arbitrary units of SCA-1 and phospho-CREB-1 identified in (J). (H) Representative viSNE maps of FAPs isolated by MACS from mdx mice and then incubated either to GM or to AIM. The upper maps show expression level of SCA-1, while the lower maps show the level of phospho-CREB-1. n = 3. (I) Representative viSNE maps showing the two clusters produced by the clustering approach. (J) Dot plot showing the expression level of SCA-1 and the level of phospho-CREB-1 (both in arbitrary units) in the metaclusters from (I). Data are presented as mean ± SEM. ** p ≤ 0.01, *** p ≤ 0.001. Scale bars 100 μm.
