• Study used Predictive Oncology’s vast biobank of cryopreserved live cell tumor specimens for the production and testing of primary patient tumor spheroids
• Results presented at the 2025 Society for Laboratory Automation and Screening (SLAS)

PITTSBURGH, Feb. 10, 2025 (GLOBE NEWSWIRE) -- Predictive Oncology Inc. (NASDAQ: POAI), a leader in AI-driven drug discovery and biologics, today announced that positive results from an ongoing study in collaboration with Switzerland-based Tecan, Ltd. were recently presented at the 2025 Society for Laboratory Automation and Screening (SLAS) International Conference & Exhibition, which was held January 25-29, 2025, in San Diego, CA.

Cancer research increasingly relies on patient-derived tumor models (PDTMs), such as patient-derived tumor spheroids (PDTS), to develop personalized therapies as they offer a more physiologically relevant system, preserving the morphology, cellular complexity, and microenvironment of corresponding tissues. A key challenge of utilizing PDTS is the accessibility and scalability of primary tumor cells. The use of cryopreserved dissociated tumor cells (DTCs) which are single cell suspensions dissociated from solid tumors addresses this limitation, and offers a robust method to store and culture viable DTCs for research.

Optimized growth conditions and drug treatment protocols were established for tumor models derived from cryopreserved DTCs of different cancer types. 3D models are closer to in vivo physiological conditions than 2D models, and as expected, differences in response to drug dosing are observed.

“The capability to obtain a tumor specimen and monitor its growth and drug response as it transitions from a 2D cell culture to cryopreservation and then to a 3D cell culture significantly enhances the relevance and availability of our samples for high-throughput drug discovery, personalized medicine, and biomarker discovery,” said Dr. Arlette Uihlein, Senior Vice President of Translational Medicine and Drug Discovery and Medical Director at Predictive Oncology. “The breast, colon and ovary samples used to generate primary patient spheroids were selected from the Predictive Oncology biobank. All samples were chosen based on known drug response data indicating responsiveness to the clinically relevant compounds used in this study.”

The high throughput screening [HTS] market is projected to reach $69.5 billion by 2032, reflecting a CAGR of 12.18%, according to SNS Insider research. There is a growing adoption of 3D cell cultures and organoids, which provide more physiologically relevant models for screening, enhancing the predictive power of HTS assays.

A major obstacle to the use of patient-derived tumor spheroids in research and drug development is the limited accessibility and scalability of primary tumor cells. This challenge is mitigated by the utilization of cryopreserved dissociated tumor cells (DTCs), which represent a scalable resource for experiments with viable primary tumor material.

“This process requires precise monitoring and characterization, including multiple imaging techniques and viability assessments to evaluate tumor growth and drug response. The studies presented in this poster summarize recent developments in the use of the POAI biobank for optimizing the use of DTCs, by multiplexing label-free artificial intelligence based automated analysis of tumor spheroids over time with real-time drug dose response,” said Eric Lutsch, Application Scientist at Tecan, Austria. “The spheroids were evaluated using the Tecan SparkCyto instrument and 3D^AI software capabilities.”
