Arsenic transforms normal stem cell in to cancerous stem cell which are responsible for seedy tumor growth in their presence.

Arsenic transforms normal stem cells in to cancerous stem cells; tumor growth is enhanced by cancerous stem cells.

Researchers at National Institute of health found that normal stem cells when exposed to inorganic arsenic get transform from normal stem cells in to cancerous stem cells, when such cancerous stem cell comes in vicinity of a normal stem cell even though there is no actual contact , normal stem cell becomes cancerous rabidly and transforms surrounding normal cell in to cancerous.

The bio-molecular and chemical signals from affected stem cells to normal stem cell are responsible for transforming normal stem cell in to cancerous stem sell.

The study will be of greater value in designing and developing drugs and cellular therapy products in future for treatment of cancer.

The mechanism which is responsible for rapid spread was discovered by Dr Michael Waalkes, his colleagues at the National Toxicology Program Laboratory, National Institute of Environmental Health Sciences,(NIH).

Stem cells are basal cells in our body which has capability to differentiate themselves in to various different tissue cells and give rise to new tissue cells by which damaged tissue get repaired.
Therefore stem cells are looked by many researchers as great tool for regenerative medicine, many cancers too are treated with stem cell treatments.

Contaminations of drinking water with inorganic arsenic are main cause of worry which should be addressed by every one around world.

Further researchers will focus their research on finding if the observations are specific to arsenic or other heavy metals and inorganic carcinogens too show similar results.
