Description_x000D_ Application_x000D_ HyStem® cell culture scaffold kit has been successfully used to expand human embryonic stem cells (H9s), umbilical cord blood CD23+ stem cells, hepatic stem cells and hepatic progenitor cells._x000D_ Features and Benefits_x000D_ 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._x000D_ • 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._x000D_ • 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_x000D_ • 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._x000D_ With Hystem, researchers can tailor the incorporation of ECM proteins, cell attachment factors, and growth factors as well as the elasticity of the hydrogel and cell incorporation (encapsulations or top plating) to create the specific 3D environment required by their cells._x000D_ Hystem is recommended for both in vivo and in vitro experimentation._x000D_ Hystem offers a minimal number of cell attachment sites. If desired, researchers may incorporate attachment factors of their choice._x000D_ Legal Information_x000D_ Hystem is a registered trademark of BIOTIME, INC
