Fig. 4
In vitro MRI dose response of Nanomag-labelled MSCs encapsulated in 2.5 mg/ml collagen type 1 gel. A and B are MSCs labelled with Nanomag for 1 h and 24 hrs respectively. C and D are MSCs labelled with GET-Nanomag for 1 hr and 24 hrs respectively. For each subfigure, i is the T2eff measurement produced from the MRI image and ii is the corresponding T2eff plots. Data represents mean T2eff values ± s.d. (n = 3) with significance determined by two-way ANOVA statistical test where * is p < 0.05, ** is p < 0.01, *** is p < 0.001 and **** is p < 0.0001
