Customizable and free of animal components, Hystem hydrogel cell culture scaffolds provide a complex, three dimensional environment in which cells are able to proliferate, much as they would in vivo. Customizable - each distinct cell type in a multicellular organism has its own unique microenvironment. Hystem offers the flexibility to tailor the environments of cultured cells to mimic their in vivo counterparts and optimize proliferation and differentiation. Animal Component Free - As a synthetic Hyaluronic acid-based matrix, Hystem offers complete control of the cellular environment. All components are well-characterized, consistent, and derived from non-animal sources. Biologically accurate - Rich in hyaluronic acid, the Hystem hydrogel closely mimics the complex three dimensional cellular environments found in life, providing an optimal environment for culturing your cells.

3dGRO® Human Colon Organoid Expansion Medium is a complete ready-to-use serum-free medium for the expansion and long-term culture of human colonic organoids. The medium has been validated for use with 3dGRO® Human iPSC Derived Colon Organoids (Cat. No. SCC300). Colon organoids propagated in the medium express colon-specific markers including the posterior hindgut marker CDX2, a-carbonic anydrase II (CA-II), a-carbonic anhydrase IV (CA-IV), and goblet cell markers Mucin-2 and Mucin-5B.
