Use of neuro-glial cell lines for transplantation therapy
Patent Number: 5869463This patent covers a type of stem cell that is isolated from fetal brain that is useful for the treatment of neurodegenerative disease.
Blood-borne mesenchymal cells
Patent Number: 6174526This patent teaches the use of circulating mesenchymal stem cells for treatment of wounds.
Blood-borne mesenchymal cells
Patent Number: 5846796This patent covers mesenchymal stem cells that are circulating in the blood. This patent is interesting since the cells covered contain the hematopoietic stem cell marker CD34, which is usually not believed to be expressed on mesenchymal stem cells. Additionally, the marker CD45, is usually a hematopoietic associated marker, but it too is...
Blood-borne mesenchymal cells
Patent Number: 5804446This patent covers a type of stem cell that circulates and is mesenchymal in nature. The cell phenotype is CD34+ and CD45+, both being markers of hematopoietic and not classical mesenchymal stem cells.
Blood-borne mesenchymal cells
Patent Number: 5654186This patent covers a special population of stem cells that circulate in peripheral blood. Although the patent uses the word "mesenchymal" to describe the cells, these may not be true mesenchymal cells since they possess hematopoietic markers such as CD34 and CD45.
Parthenogenic oocyte activation
Patent Number: 6194202This patent covers the generation of embryonic stem cells through parthenogenesis in cows. Parthenogenesis involves activating the oocyte to differentiate in absence of sperm.
Parthenogenic oocyte activation
Patent Number: 6077710This patent covers the generation of embryos through virgin birth or parthenogenesis. Essentially if an oocyte is activated through the induction of calcium flux it can generate an embryo-like structure which can be used to derive stem cells.
Parthenogenic oocyte activation
Patent Number: 5496720Parthenogenesis comes from Greece and essentially means "virgin birth". This patent teaches how to induce parthenogenesis in a bovine oocyte through induction of calcium flux. The induction of parthenogenesis leads to activation of the oocyte and can be used as a method of generating autologous stem cells for woman.
Pluripotential quiescent stem cell population
Patent Number: 5807686This patent covers an early hematopoietic stem cell that is identified by unique physical characteristics. It is interesting to see how this patent is read in light of other patents dealing with hematopoietic stem cell populations.
Liver reserve cells
Patent Number: 5559022Liver stem cells are very interesting to study, in part because of the very potent regenerative ability of the liver. In this patent a type of liver stem cell is claimed called the "liver reserve cell". These cells are characterized by ability to be stained by methylene blue and Azure A, adherence, multinucleation, ability to differentated, and specific density on percoll.
