Manual treatment, staining, and processing of spheroids and organoids is typically labor-intensive and prone to disruption or loss of samples.
Here we report on use of our microfluidic-based Pu•MA System™ 3D to perform automated assays with single spheroids and populations of organoids followed by a metabolomic profile of spheroids with and without treatment of compounds and immunostainings. The automated pipetting steps allow high reproducibility of results and saves expensive reagents or antibodies at the same time. Different types of plate holders are available for individual assay or analysis requirements.
Spheroid Toxicity & functional assays
Single spheroids or spheroid populations can be incubated with and without compounds for several days, and then analyzed with different parameters. Collecting supernatant in combination with cell viability assays or stainings are possible for single spheroids or population of structures. Low attachment flow chips allow long-term cultivation with automated media changes and/or treatment of the cells or co-cultivation with immune cells. Assays can be measured and analyzed direct in the flow chip, due to compatibility with plate readers in 384-well format.

Single Spheroid Metabolomics
Use of Pu•MA System™3D for automated media and compound treatment along with in situ lysing of spheroids for metabolomics. The ability to lyse organoids in situ in order to capture metabolomic profiles with minimal disruption of the spheroids shows great promise for research. All reagents are loaded into flow chips and then incubation, media exchanges, cell secretion sampling and other steps are executed by the system program with a recovery rate of up to 95% without drying cells.

Immunofluorescence staining in ECM
Immunofluorescence staining (IF) is a widely used method to identify and quantify biomarker expressions and their cellular localizations. One of the challenges faced by researchers is that IF staining of delicate spheroids/organoids tend to tedious if done manual, due to loss of samples or disruption. Automated IF staining for biomarker detection is working with different types of ECM and cell types like cell lines spheroids and patient derived tumoroids growing in natural or engineered ECM.

Immuno-Oncology & Immune Cell-Co-Culture
T-cell therapy or chimeric antigen receptor T-cell therapy (CAR-T) is becoming an important approach for anti-cancer treatments. Therefore, researchers are continually discovering new targets and mechanisms to improve the understanding of the complex tumor microenvironment. The use of the Pu•MA System allows co-culturing without disturbing the organoids and collect supernatant to analyze secreted factors. It is possible, to include staining steps for imaging the co-cultures in the automated workflow.
