From: Activated eosinophil plays a role in promoting fibrosis in endometriotic lesion

Histological evaluation of eosinophil accumulation and associated fibrosis in endometriotic lesions. (a, b) Low-power (a) and high-power (b) views of the same region stained for major basic protein (MBP), with eosinophil-rich areas indicated by white circles. (c, d) Masson Trichrome staining of the same region shown at low power (c) and high power (d). The arrow in (d) indicates an area of blue-stained extracellular matrix accumulation. (e, f) Hematoxylin and eosin (HE) staining of the same region shown at low power (e) and high power (f).
