Cell-based assays for cell cycle status have become critical for oncology research. For example, potential anti-cancer therapeu­tics rely on arresting mitosis in cancerous cells to prevent uncon­trolled proliferation.
In some forms of cancer, progression through mitosis can be stopped by merely disrupting the mitotic spindle. In others, the feedback is missing and cells proceed through mitosis without proper chromosome segregation and accumulate mutations. Cell­based assays provide an efcient method for modeling the effects of drugs on the cell cycle and quantitating the accumulation of cells in mitosis. The Leica MM Mitotic Index module for the Leica MM AF software is designed for the quantitative discrimination of mitotic and interphase cells.
cic marker, such as immunouorescence staining for Histone 3 S10 phosphorylation. Two different wavelengths are acquired and the images are analyzed with the Leica MM Mitotic module.
The module utilizes Adaptive Background Correction adapting the cell detection algorithm to the local intensity ranges between and within cells to provide the most robust segmentation available. This technique enables probe detection even with highly variable background uorescence within a single image.
The simple interface minimizes setup efforts and at the same time enables users to customize the settings and measurements to ob­tain the best possible results specic to the type of cells used in the experiments.

Easy Configuration for analysis
Customization through journaling
Multiple probe acquisition
CHO-K1 cells treated with Nocodazole for 18 hours before staining with anti-phospho-His­tone H3 (Ser28). Top: control, bottom: 50 ng/ml Nocodazole.
Image analysis
The Leica MM Mitotic Index module identifies mitotic cells (green) and interphase cells (red).
1. Select the nuclear stain image
2. Specify the cell size range
3. Set the intensity above local background
4. Select the mitotic nuclear stain image
5. Set the intensity above local background
6. Optionally choose the reporting parameters
Interactive data display
Once the analysis is run, the Cellular Results table allows you to interactively view individual cells’ data. Clicking one or multiple cells in the image highlights the data for the selected cell(s) in the table.
Journals are sophisticated and powerful macros that record and perform a series of tasks without the need for a programming language. The mod­ules can be incorporated into a Leica MM AF journal to increase the customization and auto­mation of your analysis.
Multi-parameter analysis
The application module generates a number of eld or cell-by-cell parameters, including:
• Count of mitotic and non-mitotic nuclei
• Percentage of mitotic and non-mitotic nuclei
• Total and mean nuclei area of mitotic and non­mitotic cells
• Wavelength-specic integrated and average intensities of mitotic and non-mitotic nuclei
Powerful data export capabilities
All measurements can be directly exported to a text le or Microsoft® Excel® for further analy­sis.
