摘要： It has been discovered that increasing telomerase activity in cells surrounding a wound promotes wound healing. Replication capacity is enhanced, and the mobility of the epithelial cells can be increased by 3-fold or more. Particular aspects of the invention described in this disclosure include the use of agents that increase telomerase activity in cells at the site of the wound, promoting cells to move to the site and restore an epithelial layer and the underlying stratum.

摘要： It has been discovered that increasing telomerase activity in cells surrounding a wound has a variety of effects that enhance wound healing. Replication capacity is enhanced, and the mobility of the epithelial cells can be increased by 3-fold or more. Some aspects of the invention relate to agents that increase telomerase activity in cells at the site of the wound, promoting cells to move to the site and restore an epithelial layer and the underlying stratum. Other aspects of the invention relate to compositions comprising epithelial cells in which telomerase activity has been increased, useful as grafts for the treatment of wounds.

摘要： This disclosure provides a newly developed strategy and particular options for differentiating pluripotent stem cells into cells of the hepatocyte lineage. Many of the protocols are based on a strategy in which the cells are first differentiated into early germ layer cells, then into hepatocyte precursors, and then into mature cells. The cells obtained have morphological features and phenotypic markers characteristic of human adult hepatocytes. They also show evidence of cytochrome p450 enzyme activity, validating their utility for commercial applications such as drug screening, or use in the manufacture of medicaments and medical devices for clinical therapy.

摘要： Methods and materials for culturing primate-derived primordial stem cells are described. In one embodiment, a cell culture medium for growing primate-derived primordial stem cells in a substantially undifferentiated state is provided which includes a low osmotic pressure, low endotoxin basic medium that is effective to support the growth of primate-derived primordial stem cells. The basic medium is combined with a nutrient serum effective to support the growth of primate-derived primordial stem cells and a substrate selected from feeder cells and an extracellular matrix component derived from feeder cells. The medium further includes non-essential amino acids, an anti-oxidant, and a first growth factor selected from nucleosides and a pyruvate salt.

摘要： This disclosure provides a system for overcoming HLA mismatch between an allograft derived from stem cells, and a patient being treated for tissue regeneration. A state of specific immune tolerance is induced in the patient, by administering a population of tolerizing cells derived from the stem cells. This allows the patient to accept an allograft of differentiated cells derived from the same source. This invention is important because it allows a single line of stem cells to act as a universal donor source for tissue regeneration in any patient, regardless of tissue type.
