The Novel Ultrasound Irradiation Device

NEXT
PREV
特徴・独自性
  • Dr. Katsunori Nonogaki has developed the novel ultrasound irradiation device, which can improve the autonomic nervous system activity and peripheral circulation. In addition, the ultrasoud device can improve hypertension and hyperglycemia within 20 min in subjects with drug-resistant hypertension and diabetes. Our initial device was approved in Japan (226AIBZX00028000). This device will be avaliable for the treatment of 1) muscle pain, 2) the autonomic neural dysfunction and stress-related disorders, 3) hypertention, and 4) diabetes. Moreover, the device will be usefull for your healthy life and aging care.
実用化イメージ

Our aims are to export the device internationally. We seek the investment and international business partners.

[muscle dystrophy]

Induction of skeletal muscle cells from human mesenchymal stem cells and their application to muscle degeneration

NEXT
PREV
特徴・独自性
  • 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 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.

[myelin sheath]

Induction of Schwann cells from human mesenchymal stem cells and their application to spinal cord injury and demyelinating diseases

特徴・独自性
  • 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.

[myofibroblasts]

Development of anti-fibrotic therapies with a cell line from myofibroblasts of fibrotic kidneys

NEXT
PREV
特徴・独自性
  • There are serious unmet medical needs in kidney diseases. Since fibrosis is a common terminal pathology of various kidney diseases and closely related to renal failure, anti-fibrotic therapies are plausible strategies for kidney diseases. Kidney fibrosis progresses with the emergence of myofibroblasts which produce extracellular matrix. We demonstrated that myofibroblasts originate from renal interstitial fibroblasts, which produce the erythroid growth factor erythropoietin, and that the transformation is reversible. To elucidate mechanisms of kidney fibrosis, we have established a cell line derived from myofibroblasts of mouse kidneys. It has been demonstrated that epigenetic interventions restore the cells (Replic cells) to their original fibroblastic features.
実用化イメージ

Replic cells provide useful and precise strategies to identify anti-fibrotic drugs.
