Positivity for GATA3 and TTF-1 (SPT24), and negativity for monoclonal PAX8 expand the biomarker profile of the solid
cell nests of the thyroid gland [published online ahead of print January 8, 2018].
(b) Invasive atypical squamous
cell nests in the cyst walls (black arrow) (HE; original magnification: x1 (b)).
The AE1/3 and CK7 patterns of immunoreactivity were similar with staining of the center of some basaloid tumor
cell nests in a mixed membranous and cytoplasmic pattern of positivity (Figure 4).
It has also been reported that infiltration of CD1a-positive DC within tumor
cell nests and peritumoral area correlates with decreased tumor thickness and the radial growth phase of melanomas, respectively [16].
Histological examination revealed scattered physaliphorous
cell nests with a lobular growth pattern.
The novel abdominal appendage in male sepsid flies (Diptera: Sepsidae) has a complex evolutionary history of primary gain, loss, and regain which we explore using fluorescent microscopy to compare the size, volume, and number of cells in the histoblast
cell nests that produce the appendage during pupation across six genera including an ancestral outgroup which describe evolutionary history of the appendage.
The mesenchymal stem cell seeded scaffold showed
cell nests in histology and spindle shaped cell studded submucosal surface in scanning electron microscopy.
(3) These cells then undergo proliferation and form
cell nests. In most cases, the proliferation is not maintained and the
cell nests gradually reduce in size and number.
The architecture of the tumour varied from well-defined tumour
cell nests to haphazardly distributed spindle cells.
