Morphologic features and yields of immature MoDCs.

(A) Morphologic features of immature MoDCs harvested on day 7 of culture with or without the addition of 20 μg/mL urine-derived or recombinant β₂M. Representative fields of differential interference contrast microscopy (original magnification × 300) of more than 5 separate experiments are shown. (B) Yields of immature MoDCs (viable cell counts of big cells only) from day 7 culture with or without the addition of varying concentrations (2.5-40 μg/mL) of urine-derived (U-β₂M) or recombinant (R-β₂M) β₂M. Data are expressed as a percentage of the control. Mean ± SEM from 3 experiments are shown. *P < .05; **P < .01.
