摘要:
An in vitro liver organoid is provided along with methods of making and using the organoid. The liver organoid can be manipulated to have either immature or mature characteristics. Some manipulations generate a liver organoid that supports expansion and/or differentiation of hematopoietic stem cells.
摘要:
The present invention relates to the field of extracorporeal liver perfusion and, more particularly, to a method of proliferating human hepatocyte derived cells. It comprises; a) Seeding cells into a matrix forming agent; b) Pre-culturing the matrix encapsulated cells so that they form cohesive spheroids and; c) Growing them to performance competence.
摘要:
An extrudable hydrogel composition useful for making a three-dimensional organ construct includes a cross-linkable prepolymer, a post-deposition crosslinking group, optionally, an initiator that catalyzes the reaction between the prepolymer and said the crosslinking group; live cells (e.g., plant, animal, or microbial cells), optionally at least one one growth factor, and optionally water to balance. Methods of using the same and products so made are also described.
摘要:
The present invention provides biomatrix scaffolds, a tissue extract enriched for extracellular matrix components and bound growth factors, cytokines and hormones, as well as methods of making and using same.
摘要:
The present invention relates to a method of preparing cells for 3D tissue culture, which method comprises the steps of plating the cells on a suitable surface, optionally, checking for their capability to adhere to said surface, discarding the cells which have not adhered to said surface, detaching the adhered cells and transferring them into a 3D tissue culture process.
摘要:
The present invention relates to a porous matrix for tissue engineering comprising a first biodegradable and biocompatible polymer component forming a three-dimensional primary structure with primary pores, and further comprising a second biodegradable and biocompatible polymer component other than the first polymer component selected from the group consisting of collagens, laminin, fibronectin and mixtures thereof, wherein the second polymer component forms a three-dimensional secondary structure which is contained within the interior space of at least a part of the primary pores.
