A: Training session to calculate the mitotic index.

A characteristic of tumoral tissues is that cells in tumors are doing mitosis very often.

As a consequence, when we observe a tumoral tissue, we can detect these mitosis, and use this as a diagnostic procedure.

The mitotic index is a measurement of the ratio of cells that are doing mitosis.

In this exercice, you will practice to recognize the mitosis steps from microscopy images and to determine the mitotic index from tissue samples to stablish if it is or not a tumoral tissue.
