Epidermal cell suspensions were prepared from TGF-β1 −/− mice and littermate controls and stained for CD45 and I-A antigens (LC), CD45 and TCRγδ (DETC), and CD45 and isotype control (Leukocytes), and analyzed using multicolor flow cytometry. In some experiments, DETC were also identified as CD45+Thy-1.2+ cells (% in parentheses). Nonviable cells were excluded by live gating. Data are presented as percentages of events accumulated and represent individual determinations (*) or the mean ± SEM (**) of individual determinations.
