Treatment schedule and UCX® dosage for the chronic adjuvant induced arthritis (AIA) model. In the AIA experiment, animals were randomly allocated to 6 different treatment groups. One group of induced animals remained untreated, being referred as Control untreated. Other 2 groups of induced animals received PBS by intra articular (i.a.) or intra peritoneal (i.p.) routes, respectively, being referred as Sham groups. A total of five i.p. administrations (dose: 1.000x106 cells/injection) were performed every day, from day 13 to 17. In turn, three i.a. administrations (either low dose: 0.425x106 cells/injection; or high dose: 1.7x106 cells/injection) were performed every other day, for five days, from day 13 to 17 after arthritis induction. Arrows indicate injection days. The experiment lasted for 55 days.
