Northeastern University – Holographic Imaging Cytometry Program of Excellence
The joint program of excellence between Northeastern University and PHI began in late 2014. Since then HoloMonitor technology has rapidly established itself as a technology of choice for label-free kinetic cellular analysis. The program covers several activities including:
- Establishing a network of collaborators utilizing Holographic Imaging Cytometry.
- Developing novel applications supporting research interests of the Northeastern faculty and students.
- Presenting results at scientific meetings.
- Organizing an annual technology symposium and hands-on laboratory courses.

We rely on in vitro cellular cultures to evaluate the effects of the components of multifunctional nano-based formulations under development. We employ an incubator-adapted, label-free holographic imaging cytometer HoloMonitor M4® (Phase Holographic Imaging, Lund, Sweden) to obtain multi-day time-lapse sequences at 5- minute intervals. An automated stage allows hand-free acquisition of multiple fields of view.

Methods for producing 4D plot were developed. Images from the time course were exported to ImageJ and treated as an image stack, creating a volume rendering of the cellular motion over time of analysis. The brightness threshold was adjusted to view all cells within the imaging area or only the thicker cells, a feature that allows identification of mitosis, apoptosis, and transition between mesenchymal and amoeboid cellular morphologies

Using holomonitor M4, it was found that FA-(C6+Dox)-LP treated hela cells underwent rapid progression to apoptosis (cell suicide) after 21 hours, as evidenced by a drastic drop in cell area after loss of cell membrane integrity.

The essential part of this process is the development of un-biased quantitative analytical techniques. We are reporting a successful validation of a very high content, medium throughput system in multi-well plates, employing the newly developed holographic imaging cytometer HoloMonitor® M4 for label-free time-lapse cellular analysis.”
