Notch inhibitor DAPT inhibits cell proliferation of human DDLPS cells. (A) Representative IHC staining results of N1ICD and HES1 in human adipose tissue and LPS sections (n = 4/group). Arrows point to positive cells. (B) Crystal violet staining result of DMSO or Notch inhibitor DAPT-treated human DDLPS cell line LPS246. (C) Quantification of densitometry in B. n = 3. (D) Relative expression levels of Notch target genes in LPS246 cells. n = 8. (E) Immunofluorescent images of DMSO or DAPT-treated LPS246 cells. n = 3. (F) Quantification of Ki67+ percentages of cells as in E. n = 3. Bars, 50 µm. *, P < 0.05. Bar graphs indicate mean ± SEM.
