What You Need to Know About Stem Cells

We give importance to science and research because we believe that they are crucial in our development as a nation. There is a new discovery led by Singaporean scientists. This discovery will not only benefit Singapore for it will include the whole world. There are a few Singaporean scientists who discovered a new RNA (Ribonucleic Acid) processing pathway; this is crucial in hESCs (human Embryonic Stem Cells).

Scientists from GIS (Genome Institute of Singapore) together with their equivalent from US, Canada and Hong Kong found out the critical role of a protein mediator SON in the proper functioning of hESCs. The finding was reported last September 8, 2013. You can read the details of their finding at Nature Cell Biology, an online science journal.

We should be aware of the hESCs. The first thing that we should know is the there are two types of stem cells in humans and animals-embryonic stem cells and adult stem cells. hESCs have the potential of developing into any organ type or tissue in our body. The process of developing is called pluripotency. hESCs are present in fully developing embryos for about three weeks but the hESCs produced in laboratories carry on dividing and it can last long in nutrient cultures.

The adult stem cells on the other hand are found after birth and remain active in the body throughout our lifetime. There are different types of adult stem cells. For example, there are adult stem cells that serve as a repair system which can replace cells like blood cells, bone cells and specific nerve cells. You should be aware that there is also a cancer stem cell; this cell appears to be a factor in making cancers grow. Cancer stem cells are similar to adult stem cells-they divide and produce a new stem cell. In this case, cancer stem cells can divide and produce a new cancer stem cell and a specific type of cancer cell.
