Fig. 6. Individual variation of cell differentiation in the cranial neural crest cultures treated with FGF2, FGF2+BMP2 and FGF2+TGFß1 based on double immunostaining with antibodies against COL II and SMA. Each color bar represents an average fraction of a particular cell type in ten individual primary cultures. Error bars represent average deviation for the sample for each of the cell types. Color bars indicate different types of cells: red, chondrocytes; orange, smooth muscle cells; green, pigment cells.
