Fig. 4.
Confocal fluorescence images of endometrial spiral arteries labeled with antibodies against NTPDase3 (a, e) and CD31 (b) or SMA (f). Nuclei were labeled with To-Pro®-3 (c, g). Merge images showed colocalization between NTPDase3 and SMA (h) but not between NTPDase3 and CD31 (d). Scale bars 20 μm (a–d) and 10 μm (e–h)
