Stem cells creating sensory interneurons



Spinal cord consist of class of neuron named as sensory interneurons, this neurons plays the lead role in communicating information between parts of body and central nervous system, through which sense of touch is been enabled. Paralyzed people are seriously affected by the lack of touch.
Scientists added a precise bone morphogenetic protein named as BMP4, and retinoic acid which is another signalling molecule, containing two type of mixture of sensory interneurons towards human embryonic stem cell i.e. sense that body is in space is a proprioception is given by DI 1 sensory interneurons on the other side DI3 sensory interneurons assist tem for feeling sense of pressure
To convincing pluripotent stem cell the scientists found duplicate mixture of sensory interneurons which established while adding similar signalling molecules, this are formed by reprogramming the mature cells (skin cells) of patients. The method of reprogramming has ability of creating any cell type with maintaining the genetic code of person through whom they are originated. The capability to generate sensory interneurons with a patient's individual reprogrammed cells holds momentous prospective for the formation of a cell-based treatment that re-establishes the sense of touch without immune suppression.
Researcher anticipating for generating single interneurons at a time, this is because, to make convenient for defining specific role of particular cell type, and allow researchers to initiate the technique of using this type of cell in clinical applications for those paralyzed people.  Although it have been not yet recognized the phenomenon of stem cell yield completely DI1 or completely DI3. Perhaps may be another signal pathway is been involved in this process.
Scientist have yet not determined specific formula for creating different type of sensory interneurons through growth factor, may be coax stem cells.
The major step is been taken towards defining the clinical ability of the cells i.e. implanting of DI1 as well as DI3 sensory interneurons into spinal cord of mice to look that the cells are assimilating into the nervous system  and becoming completely functional.

Do Stem Cells act as Anti-Cancer Vaccines?

Induced Pluripotent Stem Cells iPSC are originated from skin or blood cells that have been reprogrammed back into an embryonic like pluripotent cells that enables the increase of an unlimited source of any type of human cell needed for therapeutic purposes. iPS cells plays an important role in regenerative medicine. They can become many different types of cells and tissues that can help in damage repair due to trauma or disease. Recent study shows that the iPS cells training the immune system to attack or even prevent tumours.  Ten years ago, adult cells were genetically reprogrammed to behave like pluripotent stem cells. To produce the vaccine for cancer, the researchers turned to induced pluripotent stem cells.  The main aim of the study is to vaccinate a person with his or her own iPS cells to protect against the development of many types of cancer. The iPS cells mimic Anti-Cancer vaccine because, since the cancer cells resemble immature progenitor cells, which ar

RESEARCH AND TRANSPLANT OF STEM CELL

Regenerative Medicine is used to Replace tissues and Organs which are been damaged by disease. It also helpful for the permanent damaged organs. This can be done through the cell based therapy or by using cell products. Most of the regenerative medicine is depend upon the endogenous developmental or repair process and stem cell plays a main role in regenerative medicine. And they are integral part of the Regenerative Medicine. The ability of stem cell is currently being researched by the doctors and scientists it can cure untreatable diseases like diabetes, heart failure stem cell also important in drug testing .These are used in Joints, Muscle pain, Ligaments. Regenerative Injection Treatment are using autologous platelet or plasma or bone marrow Tissue engineer is the branch of regenerative medicine. Cells are building block of tissues and Tissues are the main function in the body .Tissue engineering and Regenerative Medicine is the regeneration of cells and tissues and b

Cancer stem cells

How Cancer Persists Stem cells are found in numerous tissues in the body, its life span is limited unlike with all other regular cells. They have the ability of dividing and renovate themselves for long time period. There unspecialized character justifies that ensuring cells convert into different cell type on time when one cell divides. Like, stem cells inside the bone marrow have ability of becoming bone. Fat and blood cells Likewise, there is believed that cancer stem cell is present in the main part of tumour, in the other hand there growth is also undefined and ability of self-renovate till they convert into new cancer cells. The major tumours treatment leaves cancer stem cell unmarked. Cancer stem cell can move undetectably even after treatment of major tumours effectively to the blood stream by the immune system to generate new tumours. This process is known as metastasis. These minor tumours become more aggressive year after and it’s really difficult to treat them.
