摘要:
The present invention relates to a method for diagnosing leukemia, pre-leukemia or aleukemic malignant blood diseases, a method of discriminating leukemia from pre-leukemia or aleukemic malignant blood diseases, a method of discriminating aplastic anemia from myelodysplastic syndrome, a method of diagnosing delayed engraftment of the hematopoietic stem cells after transplantation of the hematopoietic stem cells, and a method of diagnosing the graft versus host disease, each of said methods comprising quantifying stem cell growth factor (SCGF). The present invention also makes it possible to provide an agent for diagnosing leukemia, pre-leukemia or aleukemic malignant blood diseases and an agent for diagnosing delayed engraftment of the hematopoietic stem cells after transplantation of the hematopoietic stem cells or an agent for diagnosing graft versus host disease (GVHD), each containing as an active ingredient an antibody reacting with stem cell growth factor (SCGF).

摘要:
Chimeric mice were constructed by transferring human CD34+ cells (hematopoietic stem cells) into a SCID mouse. In these chimeric mice, hematopoietic stem cells persistently differentiated into immune cells. Consequently, the chimeric mice can be immunized over a long time and enable one to obtain human antibodies against arbitrary antigens containing a human self-component.

The present invention relates to multipotent stem cells derived from the interstitial tissues of skeletal muscle. The multipotent stem cell of the present invention is capable of differentiating into skeletal muscle cells, smooth muscle cells, cardiomyocytes, blood cells, vascular endothelial cells, adipocytes, osteoblasts, nervous cells, hepatocytes and pancreatic cells, and is useful for regeneration of tissues and cells and treatment for cardiac failure, hepatic insufficiency, renal insufficiency, leukemia, nerve degeneration disease, arthritis, diabetes, arteriosclerosis, and the like.
摘要:
The present invention provides an immunodeficient mouse (NOG mouse) suitable for engraftment, differentiation and proliferation of heterologous cells, and a method of producing such a mouse. This mouse is obtained by backcrossing a C.B-17-scid mouse with an NOD/Shi mouse, and further backcrossing an interleukin 2-receptor γ-chain gene-knockout mouse with the thus backcrossed mouse. It is usable for producing a human antibody and establishing a stem cell assay system, a tumor model and a virus-infection model.
摘要:
A nucleic acid-complex, containing a nucleic acid and a positively charged, water-insoluble biodegradable polymer, is disclosed. The complex has properties of sustainedly releasing a desired nucleic acid, especially DNA, to a site. The complex can be taken up by phagocytes such as macrophages and delivered to a target site, allowing the function of the nucleic acid to be exhibited in a target specific manner.

摘要:
Provided are intervertebral disk nucleus pulposus stem cells or progenitor cells that may be used for treatment of intervertebral disk disorders. An intervertebral disk nucleus pulposus cell is characterized by being isolated from the intervertebral disk nucleus pulposus of a vertebrate and is positive for at least one surface marker from among Tie2 and GD2. That is, the intervertebral disk nucleus pulposus stem cell is characterized by being at least Tie2-positive for the surface marker and) possesses a self-renewal ability as well as multipotency capable of differentiating into adipocytes, osteocytes, chondrocytes and neurons. Also provided is an intervertebral disk nucleus pulposus progenitor cell characterized by being at least Tie2-negative and GD2-positive for the surface marker and capable of differentiating into any of adipocytes, osteocytes, chondrocytes and neurons.
摘要:
This invention provides a hydrophilic membrane wherein a hydrophilic cellulose derivative of a number average molecular weight of 2000˜8000 is adsorbed irreversibly to a hydrophobic membrane of an aromatic polymer. Since an amount of leaching substances is extremely small, the membrane can be used suitably in such fields as medical applications, electronics, etc. where even a quite small quantity of leaching substances from the membranes is limited especially small.
