Introduction

　　Globally, stem cell therapy has become a primary focus in medical research. This is due to the potential it holds for the treatment of diseases such as cancer, Parkinsons disease, and diabetes. Stem cells are cells that can self-renew indefinitely and differentiate to yield specialized cells within an organism. In recent years, the commercialization of stem cell research has led to an increase in companies specializing in stem cell research. This article will focus on the primary stem cell projects that companies are currently undertaking.

　　

1. Hematopoietic stem cells (HSCs)

　　HSCs are stem cells that produce blood cells. They are currently used in transplants to treat blood cancers such as leukemia. However, HSCs also have potential in treating genetic disorders such as sickle cell anemia and thalassemia. Companies such as Pluristem Therapeutics Inc. and Celgene Corporation are currently conducting research on HSCs.

　　

2. Mesenchymal stem cells (MSCs)

　　MSCs are stem cells that are found in bone marrow and have the potential to differentiate into bone, cartilage, and fat cells. Research on MSCs has shown promise for treating conditions such as osteoarthritis and Crohns disease. Companies such as Novartis AG and Tigenix are currently researching the use of MSCs in treating these conditions.

　　

3. Neural stem cells (NSCs)

　　NSCs are stem cells that give rise to all the different types of cells in the nervous system. NSCs have been used to regenerate damaged neurons in the brain and spinal cord. Research on NSCs has shown potential for the treatment of Alzheimers disease, Parkinsons disease, and spinal cord injuries. Companies such as Neuralstem Inc. and StemCells Inc. are currently researching the use of NSCs in treating these conditions.

　　

4. Induced pluripotent stem cells (iPSCs)

　　iPSCs are stem cells that are generated from adult cells such as skin cells. They have the potential to differentiate into any type of cell in the human body. iPSCs have been used to model diseases in a dish, screen drugs, and potentially treat diseases. Companies such as Cellular Dynamics International and Fate Therapeutics are currently researching the use of iPSCs in treating various conditions such as heart disease and macular degeneration.

　　

5. Cord blood stem cells

　　Cord blood stem cells are stem cells collected from the umbilical cord after childbirth. They have the ability to differentiate into all the different types of blood cells. Cord blood stem cells have been used in transplants to treat blood cancers such as leukemia and lymphoma. Companies such as Cryo-Cell International and ViaCord are currently researching the use of cord blood stem cells in treating various conditions such as cerebral palsy and autism.

　　

Conclusion

　　In conclusion, stem cell research holds great promise for the treatment of various diseases and conditions. The commercialization of stem cell research has led to an increase in companies specializing in stem cell research. This article has highlighted the primary stem cell projects that companies are currently undertaking which include HSCs, MSCs, NSCs, iPSCs, and cord blood stem cells. The potential applications of these stem cells are vast, and we can expect continued research and development in this area.
