Sample: A human RCC tissue microarray (TMA) block was constructed by the Translational Research Initiatives in Pathology (TRIP) lab at the University of Wisconsin-Madison (UW-Madison). A section of 5um thickness was cut from the TMA block containing ~600um diameter tissue TMA cores. The section was then placed on a glass slide, stained with standard hematoxylin and eosin (H&E), and mounted under a #1.5 glass coverslip. Different tissue cores were from different patients.
HE imaging: A bright field image of the entire H&E slide was collected with an Aperio CS2 Digital Pathology Scanner (Leica Biosystems) at 20x magnification. Each core of grade 1 and grade 4 was cropped to the size of 1520 pixels by 1520 pixels using Aperio ImageScope viewing software (Leica Biosystems). In total, 75 TMA cores were verified and annotated as grade 1 and 55 TMA cores as grade 4. Each core represents an individual patient.
SHG imaging: All cores in this study were imaged with a custom built forward detection SHG microscope (Bredfeldt et al., 2014a). A MIRA 900 Ti: Sapphire laser (Coherent, Santa Clara, CA) was used to deliver 780 nm light to the sample using a 40x/1.25NA water immersion objective (Nikon, Melville, NY). No SHG signal was observed for five grade 1 cores and four grade 4 cores after navigating the system to at least 3 different fields of view on each core. Hence, in total, 70 TMA cores have SHG singal and annotated as grade1, 51 TMA cores as grade 4.
