Methods of recruiting fibroblasts by administering G-CSF

Patent Number: 7,531,510
Recruitment of various progenitor cells into injured tissue is a well known phenomena.  For example, after infarct, mobilization of bone marrow stem cells into the injured myocardium has been reported.  The current patent uses G-CSF, a cytokine that stimulates hematopoiesis and causes mobilizationInventors: Fukuda; Keiichi (Shinjuk-ku, JP), Fujita; Jun (Shinjuku-ku, JP)

Neuronal progenitors from feeder-free human embryonic stem cell culture

Patent Number: 7,531,354
This patent covers methods of generating neural progenitor cells from embryonic stem cells in absence of feeder cells.  Other patents exist that cover feeder-free technology, or technologies using non-mouse feeder cells.  The current patent covers the generation of the neural progenitors by:a. contacting adherent primate...

Clusterin-mediated inhibition of apoptosis via stromal bone marrow cell delivery to a cardiac site

Patent Number: 7,524,490
 Many diseases are associated with either too much apoptosis (eg ALS, Parkinson's, Liver failure, etc) or too little apoptosis (cancer).  The current patent covers a method to suppress apoptosis in mammalian cells.The method consists of transfecting an isolated population bone marrow derived stromal cells (either autologous or allogeneic) with a nucleic acid encoding the clusterin...

Blood and cell analysis using an imaging flow cytometer

Patent Number: 7,522,758
This patent covers methods of diagnosing diseases based on flow cytometric profile.  Although the majority of the invention is directed towards chronic lymphocytic leukemia (CLL), the first claim is rather broad:"A method for detecting a disease condition from images collected from a population of cells, comprising the steps of: (a) spectrally dispersing light from the population of...

Implantable cell/tissue-based biosensing device

Patent Number: 7,519,409
The current patent covers a device useful for detecting chemicals in a patient, with the device being implantable.  Practically the device claimed is used for implantation into the heart and provides information via electrical signals as to the chemical environment based on changes to the "biosensing" cells.  In its first claim, the patent covers "a biosensor device for...

Method of isolating human neuroepithelial precursor cells from human fetal tissue

Patent Number: 7,517,521
This patent covers methods of using a type of fetal stem cell in experimental systems or in humans.  It seems to be a clever claiming strategy.  Essentially the patent claims a method for transplanting an isolated population of human neuroepithelial precursor cells into an animal comprising: (a) isolating human neuroepithelial precursor cells from human fetal tissue by a method which...

Feeder independent extended culture of embryonic stem cells

Patent Number: 7,514,260
This patent covers methods of expanding embryonic stem cells without inducing their differentiation.  It specifically teaches feeder-free systems so that exogenous cells do not need to be used.It gets away without needing a feeder by providing 2 cytokines:noggin, and a fibroblast growth factor family member, as well as various nutrients.The first independent claim is: "A method...
