The mesenchymal stem cell seeded scaffold showed cell nests
in histology and spindle shaped cell studded submucosal surface in scanning electron microscopy.
Interleukin-2 protein and CD3 [sup]+ and CD8 [sup]+ T cells were present in the cancer stroma and cancer cell nests
A fine vascular network is often seen surrounding tumor cell nests
These cell nests
were punctated by cystic spaces and cells arranged haphazardly around spaces [Figure 2].
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.
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.
Histopathological examination revealed a lobulated tumour consisting of tumour cells showing sebaceous differentiation with palisaded germinative cell nests
at the periphery fair amount of mitotic activity (maximum 7/10HPF) and cell nests
containing central eosinophilic degenerated material and focally surrounded by lymphoid cells.
The histological sections were used to measure the height of digestive cells, the length of the striated border, the nuclear area and the area of the regenerative cell nests
