Ultrastructural and immunoelectron microscopic study of three unusual plurihormonal pituitary adenomas.

abstract：UNLABELLED:The cell adhesion molecules (CAMs) CD44 standard (CD44s) and its variant 6 (CD44v6) are involved in the progression and invasion of human malignancies. However, discrepancies in the prognostic value of CD44s and CD44v6 expression need to be addressed. AIMS:To investigate the expression of CD44s and CD44v6 i...
