Class: Extraction/Preservation (153)
Method of detecting hematopoietic progenitor cells
Patent Number: RE39,006This patent appears to cover a new method of detecting hematopoietic stem cells, without needing to use stem cell-specific markers. The patent seems to use some light and physical properties of the cells to distinguish between stem cells and non-stem cells. The patent has one issued claim which is: "A method for detecting or counting or both detecting and counting hematopoietic...
Composition and method for preserving progenitor cells
Patent Number: 7,112,653This patent covers peptides that inhibit hematopoietic stem cell proliferation, thereby allowing protection of these cells from chemotherapy or radiotherapy. This patent may conceptually be applicable to selectively inhibiting healthy stem cells while allowing leukemic stem cells to proliferate so that chemotherapy or radiotherapy may selectively kill the proliferating leukemic cells.
Composition and method for preserving progenitor cells
Patent Number: 6084060This patent discloses lectins and portions of the lectins that are capable of protecting various types of stem cells from death or inactivation.
Method of isolating mesenchymal stem cells associated with isolated megakaryocytes by isolating megakaryocytes
Patent Number: 5965436This patent teaches that mesenchymal stem cells in the bone marrow are sometimes found in attachment to megakaryocytes. The patent teaches that it is possible to extracted megakaryocytes from the bone marrow, using antibodies such as anti-CD41, and then from the megakaryocytes to de-attach the mesenchymal stem cells.
Antibody recognizing a small subset of human hematopoietic cells
Patent Number: 7,247,718This patent covers an antibody that binds CD34 cells called MG-1. This is a useful patent for people trying to circumvent Baxter's CD34 patent or Miltenyi's CD133.
Antibody recognizing a small subset of human hematopoietic cells
Patent Number: 6838282This is a patent for a unique stem cell marker that is recognized by the antibody MG-1. There are numerous stem cell markers in existence which are used for isolation of stem cell subtypes. The value of new stem cell markers is relatively high since the field is very populated. A patent such as the present one, if MG-1 has not been commercialized, can be used to position a new biotech...
Antigen found on a small subset of human hematopoietic cells which binds to monoclonal antibody MG1
Patent Number: 6242579This patent covers an antigen that is found on some types of hematopoietic stem cells. This antigen can be used for purification of hematopoietic stem cells by magnetic or flow cytometric means.
Antibody recognizing a small subset of human hematopoietic cells
Patent Number: 6043348This patent covers a new marker of hematopoietic stem cells. This marker can be used for extraction of these stem cells, as well as for quantification. The protein marker is called "MG-1" in the specification.
In vivo selection of primitive hematopoietic cells
Patent Number: 6500421This patent teaches ways of using tranfection of hematopoietic stem cells in order to select for primitive cells in vivo. This patent is useful for treatment of a variety of hematological disorders in which stem cell transplants are indicated.
Methods and compositions for neural progenitor cells
Patent Number: 6890724This patent teaches how to extract neural precursor cells by expression of a protein called RET. RET is orphan receptor tyrosine kinase essential for enteric neurogenesis The patent has two independent claims. That are: A method for the enrichment of neural progenitor cells comprising RET protein, said method comprising: a) combining...
