mitotic activity

Bizarre multinucleated cells may be present; however, there is no mitotic activity.

They are atypical smooth muscle tumors with low mitotic activity.

Marked nuclear atypia and any level of mitotic activity.

Their inter-lamellar cells have high rates of mitotic activity which are influenced by both hypoxia and temperature.

These tumours may have necrosis, hemorrhage, focal calcification and mitotic activity.

The presence of invasion and mitotic activity help differentiate small cancers from adrenocortical adenomas.

Cellular ependymoma - the most common subtype; usually demonstrates significant cellularity without an increase in mitotic activity.

Additionally, tretinoin stimulates mitotic activity and increased turnover of follicular epithelial cells.

There is usually no mitotic activity, and two cells populations (epithelial & myoepithelial) are present, like in benign breast glands.

There is usually minimal pleomorphism but less commonly there can be anaplasia, mitotic activity, and necrosis.

The center of the root apical meristem is occupied by a quiescent center, which has low mitotic activity.

Following birth, there is a resurgence of mitotic activity and excellent preparations can be obtained from the liver and spleen up to 5 days later.

The high mitotic activity of Burkitt lymphoma is confirmed by nearly 100% of the cells staining positive for Ki67.

Microglia undergo a burst of mitotic activity during injury; this proliferation is followed by apoptosis to reduce the cell numbers back to baseline.

It has been reported to have antiinflammatory effect, and to improve blood flow and mitotic activity in thioacetamide-traumatized rat livers.

If 5 or more mitotic figures are present in 10 high powered fields but the behavior still appears benign, may append "with significant mitotic activity".

Stretching the skin beyond normal expansion invokes several mechanotransduction pathways which increase mitotic activity and promote collagen synthesis.

The grade depends on how well the mast cells are differentiated, mitotic activity, location within the skin, invasiveness, and the presence of inflammation or necrosis.

Morphologic features suggesting malignancy (cellular pleomorphism, hyperchromatic nuclei, necrosis, high mitotic activity) can occasionally be seen.

Epidermis growth take place by mitotic activity in its deepest layer, into the basal layer, with slow outward migration and maturation of cells.

Immunohistochemical analysis, cytogenetic and molecular genetic findings, and measures of mitotic activity are increasingly used in tumor diagnosis and classification.

They may be considered benign, borderline, or malignant depending on histologic features including stromal cellularity, infiltration at the tumor's edge, and mitotic activity.

Because replication of PPV is affected by mitotic activity, the effect of the serum on the cells is also especially important.

Several microscopic features can affect the prognosis of intraocular melanoma, including cell type, mitotic activity, lymphocytic infiltration, and, possibly, fibrovascular loops.

Also, doubling time and mitotic activity are cornerstones of ES cells, as stem cells must self-renew as part of their definition.
