Microprinted feeder cells guide embryonic stem cell fate.
We introduce a non-contact approach to microprint multiple types of feeder cells in a microarray format using immiscible aqueous solutions of two biopolymers. Droplets of cell suspension in the denser aqueous phase are printed on a substrate residing within a bath of the immersion aqueous phase. Due to their affinity to the denser phase, cells remain localized within the drops and adhere to reg...
متن کاملHuman embryonic stem cells derived without feeder cells.
BACKGROUND Human embryonic stem cells are likely to play an important role in the future of regenerative medicine. However, exposure of existing human embryonic stem-cell lines to live animal cells and serum risks contamination with pathogens that could lead to human health risks. We aimed to derive an embryonic stem-cell line without exposure to cells or serum. METHODS Frozen cleavage-stage ...
متن کاملEpigenetic control of embryonic stem cell fate
Embryonic stem (ES) cells are derived from the inner cell mass of the preimplantation embryo and are pluripotent, as they are able to differentiate into all cell types of the adult organism. Once established, the pluripotent ES cells can be maintained under defined culture conditions, but can also be induced rapidly to differentiate. Maintaining this balance of stability versus plasticity is a ...
متن کاملHuman feeder layers for human embryonic stem cells.
Human embryonic stem (hES) cells hold great promise for future use in various research areas, such as human developmental biology and cell-based therapies. Traditionally, these cells have been cultured on mouse embryonic fibroblast (MEF) feeder layers, which permit continuous growth in an undifferentiated stage. To use these unique cells in human therapy, an animal-free culture system must be u...
متن کاملEstablishment, Culture and Freezing of Human and Mouse Embryonic Stem Cells: a Protocol Guide
Studies of the biology of human embryonic stem cells (hES cells) have developed rapidly over the past nine years since the first reports of their derivation. They clearly offer enormous potential, not only for regenerative medicine, but also for drug discovery and toxicology, human developmental biology and cancer research. Realizing these potentials a better understanding of the fundamental as...
