Learn how a new imaging center in South Korea is working to overcome existing experimental limitations with hopes to improve quality of life for cancer patients

SelectScience talks with Eunsoo Lee, Director of Research Support at Ewha Womans University Fluorescence Core Imaging Center, about its work on the observation and regulation of the microenvironment of cancer cells as it seeks to fine-tune tissue-specific methods. Here, Lee highlights the teams focus on designing and supporting experiments that require cooperative research and reveals a key technology underpinning its work.

Our center is still new, having opened just last month. It provides a variety of imaging systems to support the observation of cellular activity/the proteins and morphology of tissue samples. There is a research scientist in charge of each device to offer analytical services. I work on designing and supporting research experiments that require joint/cooperative research.

We are currently involved in research about the regulation of the microenvironment of cancer cells, as well as studying the regulation of reactive oxygen species (ROS) by organelles to determine the role and mechanisms of ROS. My personal research is to investigate the effects of tissue-specific extracellular matrix proteins on cell differentiation.

We are developing new experimental methods to control the microenvironment or control the levels of ROS freely, with the goal of further subdividing and fine-tuning them into organelle- and tissue-specific methods. For cell differentiation experiments using extracellular matrix proteins, we have developed a new method to secure tissue-specific extracellular matrix proteins and are looking to determine whether culturing stem cells in these proteins cause them to differentiate into the respective tissues cells. In this way, we try to overcome the existing experimental limitations by developing new techniques optimized for our research.

We frequently use both the LUNA-FL Dual Fluorescence Cell Counter and X-CLARITY Tissue Clearing System from Logos Biosystems - we keep the LUNA-FL where we culture our stem cells, and it is used for the qualitative and quantitative analysis of cells at each passage.

When studying the differentiation of stem cells according to their location in the brain, we have to isolate six regions of the brain and extract stem cells from each region. When using the traditional method to count cells, it is not only time consuming, but cell quality also slowly deteriorates over time. Using the LUNA-FL makes it possible to get stem cell counts from all six regions quickly while checking cell quality at the same time. Because of this, we can use a similar standard of cells every time, making our experiments more reliable.

Yes, Logos Biosystems products are generally designed with customers in mind and have the advantage of being very easy to use and fast. When it comes to the LUNA-FL, it is especially convenient that, after it counts the cells, there is a dilution calculator for subsequent experiments, and live/dead ratios that need to be recorded can be reviewed directly on the LUNA-FL. Lastly, I think most consumers would choose a product with an attractive design when considering similarly priced devices.

Early next year, Logos Biosystems will launch the newest member of the LUNA family, designed to build on the success of its predecessors: the LUNA-FX7 Automated Cell Counter.

As my research is mainly focused on using tissue scaffolds to study recellularization and tissue-specific cell differentiation, I am hopeful about this ultimately leading to the development of implants that can be used for patients. The development of tailored, purpose-specific functional scaffolds would be a huge contribution to improving patient quality of life in the field of regenerative medicine.
