ThinkCyte’s novel label-free in-silico Ghost Cytometry published in eLife

Tokyo, Japan. December 21, 2021

ThinkCyte Inc., a company focusing on the development of novel cell analytics and sorting platforms for applications in cell therapy, drug discovery, and clinical diagnostics, announced today the publication of their “in-silico ghost cytometry (iSGC)” technology in eLife. The study was led by Dr. Sadao Ota, associate professor at Research Center for Advanced Science and Technology at the University of Tokyo, and ThinkCyte’s co-founder and CSO.

The same team previously reported on the novel ghost cytometry (GC) technique, which utilizes proprietary optical designs combined with artificial intelligence to enable high-throughput, high-content analysis and sorting of cells, in a recent article in Science. Compared to conventional flow cytometry and microscopy techniques, GC can simultaneously capture high-content data with high speed and has the potential to revolutionize life science research and cell therapy manufacturing.

In this study, the team developed an “in silico-labeling” method, where a machine learning approach was used to identify unique optical features that matched cellular phenotypes. The iSGC platform could discern and classify cells based on target phenotypes, without the need for molecular markers or labels. The paper demonstrated several use cases of the novel iSGC technique including in induced pluripotent stem cell (iPSC) differentiation and 5-part differential of white blood cells (WBCs), which can be applied in clinical applications for stem cell therapy and hematologic diagnostics, respectively.

“Being able to analyze and sort cells in a label-free manner can significantly improve the overall process and workflow efficiencies in life science research and cell therapy manufacturing,” said Dr. Ota. “The iSGC platform can be integrated into process automation systems to avoid contamination risks and preserve precious cell samples, for example.”
