Detection of MNPSNP clusters (→) in smear samples (a, d, g), histological slices (b, e, h) via fluorescence microscopy and fresh tissue via MPM (c, f). a–c Group 0, mild to moderate, diffuse, differently sized clusters, partly grouped together in oval shape; d–f group 1, slightly less than group 0; g, h Group 42, rare to occasional, diffuse clusters.
