New Stem Cell Technology may help in Treating Many Diseases
Researchers from Boston and Japan have turned normal cells from mice into stem cells. The study published in the journal Nature involved cells taken from the spleen of a mouse.
These cells were then exposed to an environment, which was low in oxygen and was acidic in nature. In this state, the cells were in a condition called pluripotent. It is a condition in which the cells had the ability to get
transformed in almost all cells.
The newly formed cells were named Stimulus-Triggered Acquisition of Pluripotency Cells (STAP cells). The STAP cells were then injected into the embryos of mice that were in the early stage of development. When the embryos grew into mice then came out to be the ones that had both their original cells as well as the STAP cells.
The most interesting part of the study was when the STAP cells were able to grow into the mouse placenta cells. This was a clear indication of the fact that STAP cells can form into different types of cells.
The research has given a hope that they will be able to replicate the technology among humans in order to replace defective tissue in a number of diseases.
Currently, human cells are turned into iPS stem cells. In this technique, ordinary cells are reprogrammed and is time consuming. But such is not the case with the new method in which the cell changes its own behaviour due to external stress.
