Article Title: Epigenetic control of myogenic identity of human muscle stem cells in Duchenne muscular dystrophy

doi: 10.1016/j.isci.2024.111350

Figure Lengend Snippet: In vitro behavior of DMD-MuSCs (A–C) CD56 pos MuSCs isolated from healthy control (HC) and Duchenne (DMD) muscles were analyzed for their capacity to implement in vitro myogenesis. (A) Proliferation was assessed in growth medium (GM) as the number of EdU pos cells (red). (B) Differentiation was quantified after 5 days in differentiation medium (DM) as the number of myogenin pos cells (green) among desmin pos cells (red). (C) Fusion index was quantified in differentiated cells grown at high density, as the number of nuclei in desmin expressing myotubes (red) related to the total number of nuclei. Hoechst labels nuclei (blue). Bar: 100 μm. (D) Expression of CD56 was evaluated by flow cytometry during the culture of initially pure CD56 pos HC- and DMD-MuSCs in growth medium. (E) Calculation of the loss of CD56 per cell division from (D). (F) Experimental procedure of the clonal culture of Myf5-transduced CD56 pos MuSCs. (G) Immunostaining of clones for CD56 (red), GFP(Myf5) (green) and TCF7L2 (cyan). Hoechst labels nuclei (blue). Red arrowheads show myogenic CD56 pos Myf5 pos cells, blue arrowheads show fibrogenic TCF7L2 pos cells and yellow arrowheads show cells harboring both myogenic and fibrogenic markers. Bar: 50 μm. (H) Quantification of cells according to the immunostaining shown in (G). Each shape symbol represents one clone. Results are means ± SEM of 3–9 samples in (A–E) and of 6 clones issued from 3 HC donors and of 5 clones issued from 3 DMD donors in (H). ns: non significant, ∗ p < 0.05 using unpaired (A–E) or paired (H) t test.
