Figure 4

Accumulation of administered In-111 labeled hUTC in the stroke lesion compared to that of In-111 oxine treated animals. Images were from two representative animals in respective groups in In-111 labeled hUTC (top panel) and In-111 oxine vehicle (bottom panel). SPECT images showed higher radioactivity (A) in the lesions (ipsilateral side (dotted circle) and top panel) and the semi-quantitative analysis showed increased in the ipsilateral to contralateral ratio in animals that received In-111 labeled hUTC (n=13) or In-111 oxine vehicle (n=12) (B). * = significant differences compared to corresponding day 0, and # significant differences compared to corresponding In-111-labeled hUTC.
