4 `$ a6 b3 p# z    The fibroblast-colony-forming unit (CFU-F) assay was performed as previously reported with minor modifications (Wu et al. 2000; Vidal et al. 2007). Starting from a suspension
: Z6 a1 a2 ?3 h/ ]containing 103 cells/ml, ASCs were plated by serial dilution in 6-well plates (from 48 cells/cm2 to 1 cell/cm2)and cultured in control medium supplemented with 20% FBS.At day 6, the medium was changed and, at day 10, cells were fixed with 100% methanol and stained with 0.5% crystal violet (Fluka, Buchs, Switzerland). The frequency of the CFU-F was established by scoring individual colonies (consisting of at least 20-30 cells) with respect to the number of seeded cells.
