Human induced pluripotent stem cells: a review of the US patent landscape.
Summary of "Human induced pluripotent stem cells: a review of the US patent landscape."
Human induced pluripotent stem (iPS) cells and human embryonic stem cells are cells that have the ability to differentiate into a variety of cell types. Embryonic stem cells are derived from human embryos; however, by contrast, human iPS cells can be obtained from somatic cells that have undergone a process of 'reprogramming' via genetic manipulation such that they develop pluripotency. Since iPS cells are not derived from human embryos, they are a less complicated source of human pluripotent cells and are considered valuable research tools and potentially useful in therapeutic applications in regenerative medicine. Worldwide, there are only three issued patents concerning iPS cells. Therefore, the patent landscape in this field is largely undefined. This article provides an overview of the issued patents as well as the pending published patent applications in the field.

Medical and Biotech [MESH] Definitions
Embryonal Carcinoma Stem Cells
The malignant stem cells of TERATOCARCINOMAS, which resemble pluripotent stem cells of the BLASTOCYST INNER CELL MASS. The EC cells can be grown in vitro, and experimentally induced to differentiate. They are used as a model system for studying early embryonic cell differentiation.
Induced Pluripotent Stem Cells
Cells from adult organisms that have been reprogrammed into a pluripotential state similar to that of EMBRYONIC STEM CELLS.
Lymphopoiesis
Formation of LYMPHOCYTES and PLASMA CELLS from the lymphoid stem cells which develop from the pluripotent HEMATOPOIETIC STEM CELLS in the BONE MARROW. These lymphoid stem cells differentiate into T-LYMPHOCYTES; B-LYMPHOCYTES; PLASMA CELLS; or NK-cells (KILLER CELLS, NATURAL) depending on the organ or tissues (LYMPHOID TISSUE) to which they migrate.
Leukopoiesis
The process of generating white blood cells (LEUKOCYTES) from the pluripotent HEMATOPOIETIC STEM CELLS of the BONE MARROW. There are two significant pathways to generate various types of leukocytes: MYELOPOIESIS, in which leukocytes in the blood are derived from MYELOID STEM CELLS, and LYMPHOPOIESIS, in which leukocytes of the lymphatic system (LYMPHOCYTES) are generated from lymphoid stem cells.
Myelopoiesis
Formation of MYELOID CELLS from the pluripotent HEMATOPOIETIC STEM CELLS in the BONE MARROW via MYELOID STEM CELLS. Myelopoiesis generally refers to the production of leukocytes in blood, such as MONOCYTES and GRANULOCYTES. This process also produces precursor cells for MACROPHAGE and DENDRITIC CELLS found in the lymphoid tissue.
