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 .
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.
