  1. Notes: + = low frequency (x ≤ 25%) of cells immunopositive for Sp17; ++ = moderate frequency (25% < x ≤ 50%) of cells immunopositive for Sp17; +++ = high frequency (50% < x ≤ 75%) of cells immunopositive for Sp17; ++++ = very high frequency of cells immunopositive for Sp17 (75% < x ≤ 100%). Cyto = cytoplasmic Sp17 localization.
