Fluidigm CyTOF Technology Used to Evaluate Stem Cell Therapy as a Potential Treatment for COVID-19 Pneumonia
SOUTH SAN FRANCISCO, Calif., April 02, 2020 (GLOBE NEWSWIRE) -- Fluidigm Corporation (Nasdaq:FLDM), an innovative biotechnology tools provider with a vision to improve life through comprehensive health insight, today announced that Fluidigm® CyTOF® technology was used in a clinical study producing preliminary evidence that mesenchymal stem cell (MSC) therapy improves outcomes in patients with COVID-19 pneumonia, providing key information about potential mechanisms of action of the treatment strategy.
Results of the study, conducted by researchers in China, have been published in .1
“We used a 36-marker CyTOF panel to generate a broad immune profile of each patient’s peripheral blood before and after transplantation,” said Wenjing Wang, PhD, Associate Professor at Beijing Hepatology Research Institute, You’an Hospital. “Mass cytometry allowed us to look at all immune populations of interest in a single tube of peripheral blood mononuclear cells, enabling us to use less sample and to simplify our workflow and analysis.”
The study, which evaluated clinical outcomes as well as changes in inflammatory and immune function for 14 days in seven patients with COVID-19 pneumonia, indicated that intravenous transplantation of MSCs was a safe and effective treatment for patients with COVID-19 pneumonia, including for those in severe condition.
Pulmonary function and symptoms of these seven patients were significantly improved within two days of MSC transplantation. Three of the patients, including one classified as severe, recovered and were discharged 10 days after treatment.
CyTOF analysis found that MSC treatment of severe cases led to disappearance in three to six days of overactivated cytokine-secreting immune cells and increases in regulatory T and dendritic cells. Importantly, there was a dramatic increase in a population of CD14+CD11c+CD11bmid regulatory dendritic cells, which may have helped to tamp down the cytokine storm associated with COVID-19 respiratory disease. Separate analysis of patient serum found significant reduction in levels of TNF-α, a potent inflammatory cytokine, while IL-10, an anti-inflammatory cytokine, increased in the MSC treatment group compared to the placebo control group.
“This level of new and valuable treatment research based on broad-based immune profiling is an important front in the COVID-19 fight,” said Chris Linthwaite, President and CEO of Fluidigm. “Fluidigm is actively engaged with many researchers in government and medical institutions who are addressing the COVID-19 pandemic from the perspectives of both immune profiling and virus detection and testing, and this study underscores the critical role that our technologies are playing in the global response to the outbreak.
“In addition to our instruments, our assays and analysis software are increasingly the focus of customers in the global research community exploring immune profiling of COVID-19 infected populations. Our Maxpar® Direct™ Immune Profiling Assay™ and Maxpar Pathsetter™ analysis software are a solution for labs seeking an easily deployed, fixed panel that can incorporate novel exploratory markers as well as standard markers,” Linthwaite said.
“We are inspired by this opportunity to provide meaningful tools in efforts to develop innovative solutions to this rapidly evolving pandemic.”
