Fig. 2. Cloned dermal fibroblasts grown in 100:1 FCS-20:GAL-M. All cells in this field are desmin positive (A) indicating 100% conversion to a myogenic lineage. Cloned dermal fibroblasts grown in FCS-20 alone are desmin negative (B). Cloned cells are all positive for the mesenchymal cell marker vimentin both in the presence (C) and absence (D) of galectin-1. Nuclei are stained with DAPI. Bars, 50 µm.
