SC_11-1088_sm_supplFigure1.pdf89KSupplementary figure 1. (A) Lin−:α7 −:CD34−:Sca1+:YFP+ cells purified from the cephalic depot were cultured in chondrogenic medium and osteogenic medium. MEFs were used as positive control. Analysis of chondrogenic (upper panel) and osteogenic (lowe panel) gene expression was performed using a custom-designed Taqman Gene Signature array (Applied Biosystems).
SC_11-1088_sm_supplFigure2.pdf98KSupplementary figure 2. (A) Flow cytometry analysis of the equivalence between Lin−:α7 −:Sca1+ and Lin−:α7 −:PDGFRα+ cells in the cephalic fat and masseter of PDGFRα::H2B-eGFP mice.
SC_11-1088_sm_supplFigure3.pdf67KSupplementary figure 3. (A) Analysis of plasma insulin and glucose in WT and A-ZIP/F-1 mice, four weeks after injection of 1.75 x105 NC-FAPs or 5x104 M-FAPs. The Sham group received vehicle only. Results are shown as mean ± SEM for each group (n=4)., p, 0.05.
SC_11-1088_sm_supplFigure4.pdf261KSupplementary figure 4. (A) Lineage composition of the FAP population in the TA of WNT1-Cre/R26-YFP mice at day 3 post NTX damage. Percentages of NC-FAPs are indicated in the histograms. (B) Quantification of the total FAP populations in both the masseter and TA at day 3 post NTX injection shown as percentage of parent population (Lin- cells). Results are shown as mean ± SEM for each group (n=5). , p, 0.05. (C) Imunofluorescence staining for YFP and PDGFRα was used to study masseter infiltration following NTX damage in WNT1-Cre/R26-YFP mice. Representative images of TAs from non-damaged (D0) and day 3 post-NTX injection (D3) mice are shown. Higher magnifications are depicted on the right.
