Differential local effects of (i.p.) and (i.a.) UCX® cell administration in the AIA model. Graphical representations of % variation analysis of (A,B) paw volume regression related to naive animals, and (C, D) paw circumference regression related to naive animals, during the time scoped by the AIA model experiment, both in (A,C) systemic and (B, D) local administration of UCX® cells and Sham controls. Data is presented as mean ± SEM (n = 8).
