Modified Hyaluronan Hydrogels Support the Maintenance of Mouse Embryonic Stem Cells and Human Induced Pluripotent Stem Cells.
Summary of "Modified Hyaluronan Hydrogels Support the Maintenance of Mouse Embryonic Stem Cells and Human Induced Pluripotent Stem Cells."
These studies provide evidence for the ability of a commercially available, defined, hyaluronan-gelatin hydrogel, HyStem-Câ„˘, to maintain both mouse embryonic stem cells (mESCs) and human induced pluripotent stem cells (hiPSCs) in culture while retaining their growth and pluripotent characteristics. Growth curve and doubling time analysis show that mESCs and hiPSCs grow at similar rates on HyStem-Câ„˘ hydrogels and mouse embryonic fibroblasts and Matrigelâ„˘, respectively. Immunocytochemistry, flow cytometry, gene expression and karyotyping reveal that both human and murine pluripotent cells retain a high level of pluripotency on the hydrogels after multiple passages. The addition of fibronectin to HyStem-Câ„˘ enabled the attachment of hiPSCs in a xeno-free, fully defined medium.

Medical and Biotech [MESH] Definitions
Stage-specific Embryonic Antigens
Cell-surface molecules that exhibit lineage-restricted patterns of expression during EMBRYONIC DEVELOPMENT. The antigens are useful markers in the identification of EMBRYONIC STEM CELLS.
Embryonal Carcinoma Stem Cells
The malignant stem cells of TERATOCARCINOMAS, which resemble pluripotent stem cells of the BLASTOCYST INNER CELL MASS. The EC cells can be grown in vitro, and experimentally induced to differentiate. They are used as a model system for studying early embryonic cell differentiation.
Induced Pluripotent Stem Cells
Cells from adult organisms that have been reprogrammed into a pluripotential state similar to that of EMBRYONIC STEM CELLS.
Cells in certain regions of an embryo that self-regulate embryonic development. These organizers have been found in dorsal and ventral poles of GASTRULA embryos, including Spemann organizer in amphibians, and Hensen node in chicken and mouse. These organizer cells communicate with each other via a network of secreted signaling proteins, such as BONE MORPHOGENETIC PROTEINS and their antagonists (chordin and noggin).
Blastocyst Inner Cell Mass
The cluster of cells inside a blastocyst. These cells give rise to the embryonic disc and eventual embryo proper. They are pluripotent EMBRYONIC STEM CELLS capable of yielding many but not all cell types in a developing organism.
Although isolation and characterization of embryonic stem cells have been successful in cattle, maintenance of bovine embryonic stem cells in culture remains difficult. In this study, we compared diff...
Endothelial cells line blood vessels and coordinate many aspects of vascular biology. More recent work has shown that endothelial cells provide a key niche in vivo for neural stem cells. In vitro, end...
PURPOSE: The aim of the present study is to compare three previously described mouse embryonic stem cell derivation methods to evaluate the influence of culture conditions, number of isolated blastome...
CD44 is a ubiquitous cell surface glycoprotein, involved in important cellular functions including cell adhesion, migration, and modulation of signals from cell surface receptors. While most of these...
Hyaluronan is a large glycosaminoglycan, which is abundant in the extracellular matrix of the developing rodent brain. In the adult brain however, levels of hyaluronan are significantly reduced. In th...
Human embryonic stem cells (hESCs) are isolated from the early human embryo and have the capability to proliferate indefinitely in culture and to develop into nearly every cell of the huma...
Hyaluronan is a man-made preparation of a protein complex that occurs naturally in joints and that is often low in people with osteoarthritis. Although hyaluronan has been used in millions...
251 consecutive patients with knee arthrosis were randomized to one of three interventions: Four weekly injections of 2 ml isotonic saline (placebo), 2 ml sodium hyaluronate (hyaluronan) o...
The primary purpose of this study is to determine if cross-linked hyaluronan gel reduces the dose of radiation delivered to the rectum and the rectal toxicity of radiotherapy for localized...
The purpose of this trial is to determine if patients who received embryonic dopamine cell implant surgery showed significantly greater improvement in their Parkinson's disease than a cont...
