(a) Summary of the functional and dysfunctional inflammatory cells in five mice lines used in this study. Hydrogel sensors were implanted for a time period (1 min, 2 h, 24 h), explanted, and tested outside the mice against 100 µM progesterone. (b) The maximum sensitivity decreased with increasing implantation time in general. (c) For all mice lines, the kinetics of response slowed with longer implantation time
