Clonality of AFS cells and differentiated cells derived from was verified by retroviral marking. (a) RT-PCR analysis of mRNAs for lineages indicated using a retrovirally marked second round subclone of AFS cells. U: Control undifferentiated cells. D: cells maintained under conditions to promote osteogenic (8 d), myogenic (8 d), adipogenic (16 d), endothelial (8 d), hepatic (45 d), neurogenic (8 d) differentiation. (b) Southern blot analysis of inserted GFP retroviral DNA in differentiated cells from (a); arrow indicates 4-kbp junction fragment in BamH1 digested DNA from undifferentiated cells of a GFP positive subclone of AFS cells (lane 1) and the second round subclone (lane 2) used for transcript analysis after differentiation under adipogenic (lane 3), endothelial (lane 4), hepatic (lane 5), osteogenic (lane 6), myogenic (lane 7), and neurogenic (lane 8) conditions.
