D: Germinal layer
membranes in endobag after extraction
The characteristic laminated membrane (L) and germinal layer
(G) are illustrated; a scolex (S) is noted in the center of the field.
The cysts removed during surgery were confirmed to be of hydatid cyst aetiology by histopathological evidence of germinal layer
and by demonstration of scolices and hooklets in the aspirated HCF.
Daughter cyst formation may develop from the inner germinal layer
in the cyst cavity or exogenously.
Immunohistochemical examination with a monoclonal antibody against echinococcal cytoskeleton protein EM10 (8) showed staining of the germinal layer
and protoscolices of E.
Morphological analysis of Testicular tissue: We also studied the morphology of the cross sectional structure of testicles of normal follicles with intact germinal layer
and leydig cell and the results showed complete destruction of leydig cells partially damaged germinal layer
and destruction of sperms leading to empty spaces in the lumen of follicle of testicles in which 30% destruction of follicle was observed in the group at 30 day after the administration of K2Cr2O7 and 35% destruction of follicle was observed in the group at 30th day after administration the MgSO4 (Fig.
It has parasite-derived layers: an inner nucleated germinal layer
and an outer acellular laminated layer surrounded by a host-derived fibrous capsule.
Sections were stained with haematoxylin and eosin method which revealed eosinophilic laminated cyst wall with the germinal layer
having the scolices some attached to it and some lying free in the lumen (Figure 2A, B).
The cyst wall had an outer laminated hya-line membrane and inner germinal layer
containing nuclei in an eosionophilic protoplasmic mass.
Calcareous corpuscles are abundant in the germinal layer
and in the protoscolices of E.
Histopathological examination demonstrated a germinal layer
, lamellated ecto cyst with fibrous outer layer (Fig.
Tumors with tissue from only one germinal layer
in the orbit, i.
Daughter cysts are seen as cystic structures attached to the germinal layer
that are hypointense relative to the intracystic fluid on T1W images and hyperintense on T2W images.
The innermost germinal layer
gives rise to the scolices.
Mature teratomas are designated grade 0, displaying mature and well-differentiated tissues belonging to all three germinal layers
