3D Cell Cultures

Simply incredible 3D cell cultures

PGmatrix™ is a powerful and yet easy-to-use tool for in-vitro 3D cell cultures with high-throughput screening and accurate in vivo predictions for life science research and development.

Easy to use and highly effective

PGmatrix is incredibly easy to use and allows you to get accurate results faster than ever. Unlike traditional 3D cell culture systems, PGmatrix requires no complicated steps for preparation, no pre-chilled gel solutions, and no toxic cross-linking reagents.

The PGmatrix-Spheroid system is a 3D model system mimicking extracellular matrix that produces high content physiologically formed stem cell spheroids, tumor spheroids, or organoids (~2×10⁴ spheroids/ml) with high representation of in-vivo like information at gene and RNA levels with 15-25 proliferation doubling folds and viability of 85-95%. Importantly, these spheroids can easily be harvested from the 3D model and then can also be re-encapsulated in PGmatrix-spheroids or any other PGmatrix systems for further downstream applications, such as differentiation into various somatic cells (i.e., hepatocytes or cardiomyocytes).

The PGmatrix-Spheroids system is designed to mimic the natural extracellular matrix (ECM), a 3D network matrix composed of fibrous matrix that provides structural integrity for cell survival, with a system that can be handled at room conditions and physiological conditions.

The PGmatrix-Spheroid system is an advanced 3D model for effective and highly predictive development in arenas of drug discovery, disease modeling, cell therapy and regenerative medicine, particularly for fighting COVID-19.

The PGmatrix-Spheroid system is designed for either static well plate 3D cultures, scalable motional 3D cell, spheroid manufacturing in vivo delivery, or live spheroid shipping.
