Table 2 Immunostaining of HAS1, HAS3 and HAS2 in human ovary and its tumors

From: Expression of Hyaluronan Synthases (HAS1–3) and Hyaluronidases (HYAL1–2) in Serous Ovarian Carcinomas: Inverse Correlation between HYAL1 and Hyaluronan Content

  HAS1 staining intensity* HAS3 staining intensity* HAS2 staining intensity

  1. Benign = serous cystadenoma, Borderline = serous borderline tumor
  2. Grade 1–3 = serous epithelial cystadenocarcinoma
