Fig 3. Human SPARCL1 expression is highly detectable in all human organs examined and downregulated in their respective neoplasms.

Human SPARCL1 expression (green, arrows) was determined by immunofluorescence in various healthy and neoplastic organs of human patients (healthy, neoplastic, n = 3 for all organs except oesophagus, small intestine and lung tumor with n = 2). Isotype antibody staining of consecutive sections was used as a negative control (isotype). All tissues were counterstained using DRAQ5 (blue). Scale bar = 250 μm.
