      * Example 1: If a pathologist obtains a mitotic index of two MFs per 50 HPFs on the basis of a single count, there is a 95% probability that the true MI lies between one and seven MFs per 50 HPFs. j" Example 2: If a pathologist obtains a mitotic index of five MFs per 50 HPFs based on counting HPFs, then w = 4. What region of root has the most mitotic activity? meristem. how does cytokinesis differ in plant versus animal cells? a cleavage furrow forms in animal cells, but a cell plate forms across the equation of a plant cell. Why is pinching of the cytoplasm inadequate for cytokinesis in plant cells?

    The mitotic index using toluldine blue stain is which suggest that only % of the cells in our view were undergoing mitosis and the rest are still in interphase. The percentage of cells in each stage is related to the length of time a cell spends in each stage of mitosis. The greater the percentage of cells in a stage, the longer the time. Divide the number of mitotic cells by the total number of cells you counted to calculate the mitotic index of your tissue sample. The mitotic index is the percentage of cells undergoing mitosis in your sample. The cell cycle 33 terms. Rimsha_khan6 PLUS. Biology 1 VOCAB Cell Growth & Division 27 terms.

    —Mitotic index (MI) was defined as the mitotic cell count per 10 high-power fields (HPFs), an area mm 2. Two to 6 replicate sets of 10 HPFs were counted from invasive breast carcinomas. Two to 6 replicate sets of 10 HPFs were counted from invasive breast carcinomas. The prognostic relevance of mitotic activity was analyzed in a series of patients with node-negative breast cancer treated with locoregional therapy alone, until early relapse. Mitotic activity was evaluated as the number of mitotic figures per 10 high-power fields (mitotic activity index) or per tumor cells (mitotic index).

A review of the literature on the periodicity of cell division in shoot and root apices shows that no earlier investigator considered the possible effect of the plastochrone upon the frequency of mitosis in shoot apices.

•The percentage of cells undergoing mitosis or it is defined as the ratio of no. of cells in the dividing phase. The Linked Data Service provides access to commonly found standards and vocabularies promulgated by the Library of Congress. This includes data values and the controlled vocabularies that house them.

Purpose. The mitotic index is a measure of cellular proliferation. It is defined as the percentage of cells undergoing mitosis in a given population of cells. Mitosis is the division of somatic cells into two daughter cells. Durations of the cell cycle and mitosis vary in different cell types.

An elevated mitotic index indicates more cells are dividing. Mitotic rate is highly promising, but its interpretation remains a grey area worth closer inquiry. Melanoma Staging: Implications of Histologic Sectioning Procedures. Balch et al 1 have stated that proliferation of primary melanoma as defined by the mitotic rate is a powerful and independent predictor of survival.

As a result, primary tumor. (MC). Mitotic activity index (MAI) is reported as an index (the MC/area counted).7,10 Mitotic count is determined most fre-quently in veterinary pathology, usually at magnifica-tion, but the area counted is seldom defined, and the term often reported is mitotic index.

Mitotic index is defined as the number of cells undergoing mitosis. Mitotic rate is NOT the most important factor in a prognosis. The Breslow depth of mm. is the most important. Ideally, you'd like a mitotic rate of 0. However, that's hardly the norm.

The mitotic rate is an indication of how fast the cancer cells are dividing. However, even people with higher mitotic rates don't have to have spread. Ray Proudlock, in Genetic Toxicology Testing, Calculations and Reporting of Results. The mitotic index, the number of metaphase cells scored, the number of aberrations per metaphase cell, and the percentage of cells with structural chromosomal aberration(s) should be calculated for each ent types of structural chromosomal aberrations should be listed with their numbers.

changes in the units have been made. A rising mitotic index will cause a more rapid decrease with increasing age, and the converse will occur with a falling index.

In contrast, the mitotic index, which is a useful and simple method for analysis of cell proliferation, can be easily applied to routine clinical practice.

The prognostic role of mitotic index in patient survival has been confirmed in several cancers. The mitotic index is used for tumor grading of breast and ovarian cancers [8,9]. Fluctuations in Mitotic Index in the Shoot Apex of Lonicera nitida.
