Advanced microscope finds cancer cells that matter

Scientist Miao-Ping Chien and her team have designed and built a completely new type of microscope. In doing so, Chien hopes to boost research into rare cancer cells. ‘We can image tens of thousands of individual cells at once.’

Dr. Miao-Ping Chien

You could call Miao-Ping Chien the personification of multidisciplinarity. She studied molecular genetics, did PhD research in chemistry and then immersed herself in medical engineering. This career path was no accident. “I always say: every scientist should be multidisciplinary.”

In 2017 Chien came to Erasmus MC, with the idea for a new technique to image rare cancer cells in the back of her mind. ‘I noticed what was missing in cancer research and had the knowledge and capabilities to fill that gap.’ In three years, her initial idea has started to grow into a start-up company. Under the name of UFO Biosciences, Chien markets a so-called high throughput single cell screening microscope. A device that she and her team designed and built herself, thanks to their knowledge of various fields.

Desktop computer

The new microscope is about the size of an old-fashioned desktop computer. ‘It’s actually a combination of a lot of lenses, mirrors, lasers and filters’, Chien explains. By cleverly combining these parts, the device solves a dilemma. Scientists want to study individual cells in great detail. This can be done with a normal microscope by extremely enlarging the image. But if you want to image many cells at once, you have to zoom out again and you lose sight of the individual cells. It was therefore impossible to image many cells at the same time with a high resolution.

Cancer researchers

The new microscope can image as many as tens of thousands of individual cells simultaneously without losing resolution. And it doesn’t stop there. ‘We can monitor the behavior of individual cells, isolate single cells, extract and read the DNA or RNA. We call that sequencing’, says Chien. This is especially helpful for cancer researchers, she thinks. ‘A tumor is not a homogeneous mass, it contains several types of cells. Some are the aggressive ones: they cause metastasis or are resistant to treatment. We are looking for those rare cells. If we can figure out why they are acting so maliciously, we can develop new drugs that target them.’

In the beginning Chien did many things herself, but that has now changed. ‘The biggest challenge was to find the right people. I now have a fantastic team of people who understand technology, image processing and cancer biology. I am also grateful for the support of my department head, the Oncode Institute and Technology Transfer Office at Erasmus MC. They helped me with the business plan so that I can continue to focus on science.’

Service

Chien and her team have now built two high throughput single cell screening microscopes, funded by the Josephine Nefkens Stichting (JNS) program, Erasmus MC and Oncode Institute. From 2021, they will offer their devices and expertise as a service to fellow scientists, from Erasmus MC and far beyond. ‘Scientists can send their samples to us. Our team will do the imaging, isolation and sequencing’, she explains.

More efficient cancer therapies possible: better for patient, healthcare costs, and environment

Internist and oncologist Stefan Sleijfer and hospital pharmacist Roelof van Leeuwen of Erasmus MC Cancer Institute are working closely together to make cancer therapies more effective. This is not only good for patients, but also for public coffers and for the environment. These efforts save the department of Internal Oncology about EUR 7 million per year.
