- We have developed a methodology for identifying general ignition and combustion characteristics of gaseous and liquid fuels including bio and synthetic fuels. It enables identification of ignition and combustion characteristics of new fuels prior to application for practical combustion devices. The reactor system consists of a small diameter channel which has a temperature gradient from room temperature to the auto ignition temperature and thus reaction characteristics in different temperature levels can be easily investigated. Such a measurement had required research level skills and special devices such as rapid compression machine or shock tube which is costly in general, however, the micro flow reactor with temperature gradient enables reaction analysis easily.

- Effective drug delivery to central nervous system is promising as a new therapeutic strategy against various central nervous system disorders. However, it represents a challenge because systemic delivery is always hindered by blood brain barrier, and local delivery cannot be effective because of the restricted distribution. Recently, local drug delivery system that can achieve robust distribution of the infusates by maintaining a pressure gradient at the tip of the infusion catheter during infusion has developed. Although this method is promising, there still exist several problems as loss of infusates by backflow through catheter tract or inconsistent distribution. We recently developed a method to deliver agents with this method under MRI guidance, and now performing clinical trial to treat recurrent gliomas.

Focal central nervous system disorders such as tumor, epilepsy, and parkinson's disease can be the target for application of this technique. Developments of the new catheters and pre-infusional similation systems are on their way. We are searching for effective collaborative research in this field.

- To properly understand the functions of biomolecules, it is essential to observe them under physiological conditions where the interactions with other biomolecules are preserved. Therefore, we are developing new functional molecules using both organic chemistry and protein science approaches, and working on the visualization and optical control of biomolecules and their functions. Especially, we have developed fluorescent probes that quantitate the concentration of biomolecules or ions in subcellular regions such as organelles and caged compounds and photoswitches that optically manipulate the biomolecular functions.

- 概要
The recent spate of extreme weather events is threatening to reduce crop seed and fruit production. We have identified a catalog of genes that respond under low and high temperature stress, and will construct a system that enables production under temperature stress through genome editing and other methods.
- 従来技術との比較
In addition to conventionally used genetic recombination methods, genome editing technology has made it possible to modify genes that can be used for practical purposes.

- Crops are important for food, environment recovery, energy production, and amenity activity for human being. For improvement of crop seed production, the breeding of crops having environmental stress, is important. Especially the developmental stage from pollination to fertilization is quite weak for these environmental stresses. Thus, by breeding of reproductive trait, we will establish the high productivity and quality of crop seeds. From our research, we found several stress-tolerant genes. We already started the research by both basic and applied level.

For application, we evaluated by taking prize for application in 2001. And our basic data has been published in international Journal, "Nature" and "Science". If anyone is interested in these genes, we hope to conduct to collaborative research for establishing the useful breeding lines.

- Bone marrow stromal cells have great advantages since they are already applied to patients either by auto- or allo-transplantations, can be harvested in large numbers (10 million cells within several weeks) as adherent cells from bone marrow aspirates, and are with low risk of tumorigenesis. We have established a system to induce neural precursor cells from human bone marrow stromal cells by introducing cells with Notch intracellular domain gene plasmid followed by culturing in neurosphere method. This induction system successfully generates neural precursors which were effective for stroke (J. Neuropathol. Exp. Neurol. , 2005; J Cereb Blood Flow Metab, 2009). They could be further developed into dopamine producing neurons by treating them with cytokines including GDNF (J. Clin. Invest, 2004). The efficiency and safety of induced dopamine neurons were confirmed by rat and monkey model of Parkinson's disease. Importantly, long-term survival of auto-transplanted induced dopamine neurons were verified by 11C-CFT PET scan (J. Clin. Invest, 2013).

- Bone marrow stromal cells have great advantages since they are already applied to patients either by auto- or allo-transplantations, can be harvested in large numbers (10 million cells within several weeks) as adherent cells from bone marrow aspirates, and are with low risk of tumorigenesis. Furthermore, marrow bank is available. Likewise, mesenchymal cells harvested from umbilical cord are also easily accessible from cord bank and are a good source of mesenchymal stem cells. We have established a system to induce functional Schwann cells (peripheral glia) from human bone marrow stromal cells and umbilical cord mesenchymal cells by treating cells with a series of reagents and cytokines. This induction system successfully generates Schwann cells with very high efficiency (~97%). They were confirmed to elicit neural regeneration in peripheral nerve damages and spinal cord injury (Eur, J. Neurosci, 2001; J. Neurosurg, 2004, J. Neuropathol. Exp. Neurol, 2005, Biochem Biophys Res Commun, 2007; Tissue Eng., 2011). The efficiency and safety of induced Schwann cells were demonstrated in monkey by 1 year follow up (Exp. Neurol., 2010). Importantly, induced cells not only elicited neural regeneration in both peripheral and central nervous system, but also contributed to functional recovery by restoring myelin and saltatory conduction. Therefore, these cells are expected to be effective to demyelinating diseases as well. We hope to collaborate with companies and research groups who are willing to utilize our system.

We have established a system to induce skeletal muscle cells from human bone marrow stromal cells by treating cells with cytokines followed by Notch intracellular domain gene plasmid introduction. This induction system successfully generates skeletal muscle lineage cells comprised of muscle stem cells, namely, satellite cells, as well as myoblasts and myotubes. Transplantation of satellite cells and myoblasts were effective for muscle regeneration (Science, 2005). Importantly, induced satellite cells integrated into satellite cell location and continuously contributed to muscle regeneration. Our research team is now pursuing the safety and efficiency of these induced cells by using canine muscle degeneration models. We hope to collaborate with companies and research groups who are willing to utilize our system.

- Anemia is a very prevalent disease. Nevertheless, an effective therapy is yet to be discovered. Erythropoietin is effective only for those with renal dysfunction. We have found that inhibition of an enzyme for epigenetic regulation results in a prominent increase of erythropoiesis, pointing to a new target for anemia therapy. We have also generated a new, cell-based assay system for the enzymatic activity and carried out small molecule screening.
- Collaboration with industry partners
- We are seeking a collaboration to accelerate the development of new anemia drugs based on these findings. Together we will advance the development of the candidate molecules currently identified as well as conduct further screening of larger chemical space for better candidates and/or for drug repositioning.

- The cold spray (CS) technique is known as a new technique not only for coating but also for thick depositions. It has many advantages, i.e. dense coating, high deposition rate, low oxidation, and no phase transformation. We have been carrying out establishment of innovative preparing and coating techniques using the CS, and maintenance of reliability and safety of the cold sprayed repairing parts and coatings. Moreover, in order to evaluate the compatibility between a substrate material and particles based on an adhesion mechanism and scientific basis, various adhesion conditions are examined a micro / nano-structure observation and a molecular simulation.
