Immunophenotypic analyses in chondrogenically induced human peripheral blood aspirates upon rAAV‐mediated gene transfer. Aspirates were transduced with rAAV‐lacZ or rAAV‐hTGF‐β or left untreated (as described in Figs. 1–6), kept in chondrogenic medium for 21 days, and analyzed for the coexpression of (A) CD105/type II collagen versus CD34/type II collagen and (B) CD105/type I collagen versus CD34/type I collagen by specific coimmunostaining, as described in Materials and Methods (original magnification, ×20; all representative data). Abbreviations: hTGF‐β, human transforming growth factor‐β; rAAV, recombinant adeno‐associated viral.
