Microtissues® Inc. announced today the signing of a Supply and Distribution Agreement with Sigma-Aldrich® Corporation (Nasdaq: SIAL) for the worldwide sales and marketing of the 3D Petri Dish®, a new technology for the culture of living cells in three dimensions (3D). Invented at Brown University, the 3D Petri Dish® maximizes cell-to-cell interactions critical for replicating the function of natural tissues and organs. Shown in numerous peer reviewed papers to work with over fifty different cell types, including cell lines, primary cells and stem cells, the 3D Petri Dish® has applications in cancer research, drug discovery, toxicity testing and regenerative medicine.

“Researchers are rapidly recognizing the importance of 3D cell culture and its ability to reliably mimic in vivo function” said Brian Morgan, Director of Business Development, Microtissues® Inc. “The 3D Petri Dish® creates a natural 3D environment without artificial scaffolds and we’re excited that this distribution agreement will bring our unique and innovative line of products to the worldwide research community.”

Unlike the conventional plastic Petri dish where cells are grown as a thin layer on the surface of the dish, the 3D Petri Dish® forms 3D aggregates of cells. Spheroid size is controlled by the number of cells seeded and hundreds of uniform sized spheroids are formed in a single pipetting step. Spheroids are formed in a well ordered array in a stable platform suitable for long term culture. All spheroids are positioned on the same optical plane making them easy to image (phase contrast, fluorescent). Spheroid size is controlled by the number of cells seeded and a mixture of cells forms mixed spheroids, suitable for investigating tumor-stroma interactions. Spheroids can be grown from single cells, applicable to the study of cancer stem cells. For histology, Western blots and RT-PCR, spheroids are harvested by simply inverting the 3D Petri Dish®. No need to dissolve or digest the gel. The 3D Petri Dish® is a new fundamental tool for the world wide industry of life sciences research.
