Stem cells need to be maintained in a quiescent state when they are not needed to make new cells. This is because if stem cells were consistently proliferating then there would be a high propability of mutations, thus leading to cancer. One of the methods that stem cells maintain themselves in a non-proliferating state is through autocrine secretion of inhibitory factors. ...
Essentially, this patent covers: a) fetal and embryonic derived neurospheres; b) purified population of multipotent neural derived from juvenile or adult mammalian CNS tissue; and c) in vitro cell culture composition derived from mammalian CNS consisting of neurospheres.
Specific neurospheres include cells that resemble neuronal progenitor cells. The phenotype of...
This patent covers ways of manufacturing cells that express dopaminergic neurons for implantation. Obviously one of the uses for these cells is treatment of Parkinson's.
While others have generated dopaminergic neurons from sources such as subventricular zone precursors, olfactory epithelium, and
This patent covers the inhibition of placental growth factor as a method of treating osteoporosis. The one issued claim is restricted to inhibition of placental growth factor using an antibody or fragments of the antibody.
The inventor demonstrated inhibition of bone resorption in an animal model, as well as in vitro using anti-placental growth factor antibodies...
This patent covers a method of culturing cells, including stem cells by providing flow conditions simular to what may be found in an in vivo system. The invention aims to meet the following goals: (1) supplying a substance uniformly to the cells to be cultured; (2) establishing a uniform flow for supplying a substance; (3) eliminating a dead space; and (4) preventing release of cell...
Dendritic cells are the most potent stimulators of the immune system. Generally it is the dendritic cell that picks up antigens and makes the decision whether the immune system should "get mad" and go after the antigen, or whether the antigen represents no substantial danger and therefore should be ignored. In some cases the dendritic...
This patent covers the generation of vascular smooth muscle cells from embryonic stem cells through specific culture conditions. In one embodiment the differentiation is induced through exposure to the cytokines TGF, angiopoietin, and platelet derived growth factor BB.
In the examples section the generation of SMA positive cells from embryonic stem cells is demonstrated, as...
This patent covers specific conditions for assessing ability of hematopoietic stem cells to proliferate or become metabolically active after exposure to a test agent in vitro. Essentially the patent is useful for the screening of small molecules using high throughput systems for identification of hematopoietic stem cell modulators.
Specific hematopoietic stem cells covered in the...
It is known that stem cells migrate towards injured tissue in response to chemotactic gradients. For example the basal SDF-1 gradient made by bone marrow stromal cells is why it is possible to achieve hematopoietic reconstitution by injecting donor cells intravenously. Similarly, SDF-1 acts as a gradient to call stem cells into damaged myocardium after a...
