Tissue sections of 30 μm thickness were analyzed at ALS, 10.3.2 and APS 18-ID-D beamlines, while 10 μm thick sections were used for high resolution measurements at APS, 2-ID-D beamline.

†

Sections aged 16 weeks old were imaged at APS 18-ID-D (BioCAT) were used for analysis. All other sections used for analysis in Fig. 4 were imaged at ALS 10.3.2.
