Embryonic germ cells, method for making same, and using the cells to produce a chimeric porcine
Patent Number: 6194635This patent teaches how to generate embryonic germ cells. These cells may be used for transgenic and knockout experiments, as well as for generation of stem cells with unique properties.
Unactivated oocytes as cytoplast recipients of quiescent cell nuclei while maintaining correct ploidy
Patent Number: 6525243This patent teaches ways of improving efficacy of cloning through nuclear transfer into oocytes that are in specific stages of proliferation. The use of cloning for generation of autologous embryonic stem cells offers incredible potential for regenerative medicine.
Unactivated oocytes as cytoplast recipients of quiescent and non-quiescent cell nuclei, while maintaining correct ploidy
Patent Number: 6252133This patent covers a method of increasing efficacy of the cloning process. Cloning may be used as a source for the generation of stem cells of the embryonic type.
Neuronal progenitor cells and uses thereof
Patent Number: 6251669This patent covers a type of neural stem cell. In one embodiment the stem cells can be differentiated into gamma aminobutyric acid (GABA) expressing neurons.
Neuronal progenitor cells and uses thereof
Patent Number: 5753505This patent provides a new type of neural stem cell that can be used for screening or therapeutic purposes.
Method of isolating bile duct progenitor cells
Patent Number: 5861313This patent covers a type of stem cell that is isolated from the bile duct that can be induced to differentiate into various types of pancreatic cells including islets.
Human oligodendroglial progenitor cell line
Patent Number: 5830651This patent covers a neural stem cell line that can differentiate into neurons, oligodendrocytes, and glial cells. This cell line can be used for drug discovery since it provides a uniform cellular population. These cells may be purchased by the public from ATCC.
Liver parenchymal cells having clonal growth ability, method for obtaining same, method for subculturing same, and subculturing system of primary hepatocytes
Patent Number: 6004810This patent covers a type of liver stem cell that is useful for the treatment of various hepatic diseases. It will be interesting to compare this patent to the other ones in this directory that cover liver stem cells.
Method of preparing an undifferentiated cell
Patent Number: 7,410,773This patent is either way ahead of its time, or there are some problems in its commercialization. The patent covers a method of "dedifferentiating" mature cells in order to an immature phenotype or to increase the ability of the cells to act like stem cells.
The first claim of the patent covers a means of augmenting the number of cells expressing a stem cell...
Primate embryonic stem cells
Patent Number: 6200806This is one of the patents that cover embryonic stem cells. These patents are under much controversy since they cover the composition of matter for all embryonic stem cells.
