Cell death

Dysregulation of the cell death pathways has been attributed to several diseases and disorders such as cancer, autoimmune diseases, and neurodegenerative disorders. Determining the type of cell death is crucial for understanding the cell death mechanism and thus for the planning of therapeutic approaches and drug designing.

Different cell death modalities are characterized by their specific sequential morphological patterns.

Q-Phase detects the quantitative values of cell dry mass and morphological changes of each cell across time, thus providing a rapid and label-free method for the prediction of the provisional type of cell death.

Moreover, Q-Phase constitutes a comprehensive tool that merges both QPI and fluorescence which allows for studying the time-dependent morphological changes simultaneously with the concomitant biochemical markers.
