Figure 4. CD133−CD55− common progenitors contributed to perivascular cells but not vasculature in vivo.

(A–C) iCys scanning of KC graft sections derived from GFP labeled CD133−CD55− progenitor. The sections were stained with antibodies against CD31(A), αSMA (B) or CD140a (C). Arrows indicate locations of donor-derived green cells. (D) Representative FACS analysis of CD140a expression in GFP+ graft cells.
