Fig 5. In vitro B cell differentiation of lineage negative progenitor cells (lin-).

Fig 5

(A) Schematic for differentiation experiments. (B) Representative FACS plots of undifferentiated lin- cells and of those differentiated for 14 days; top panel—B220 and CD19 cell surface markers; bottom panel—forward scatter and Gr1 cell surface marker; undifferentiated cells were cultured in stimulation media; B cell differentiation cells were either untreated (DMSO), or treated with p38 MAPK inhibitor (SB-p38i), or ERK1/2/5 inhibitor (U0126-ERKi); the percentages of CD19, B220, or Gr1-positive cells are indicated. (C) Representative result of day 14 B cell differentiation of cells over-expressing empty vector (EV), WT, or EED MEF2C, treated with DMSO or SB-p38i; differentiation was measured by the expression of cell surface markers B220 and CD19 (left) or Gr1 (right). Two separate experiments were performed with similar results.
