Dr. Lee did this research on the signaling system that is how a single signaling system which is known as nodal or Activin pathway gives the signal to stem cells. He with his fellow scientists studied how on receiving these signals, stem cells decide which type of cells they should become. This nodal pathway in actual is capable to specify the wide range of cell types. In other words, it is a challenge to the perception of many individuals that chemical signal system is specific and can control limited outcome. The research has provided itself to be a leading step in the field of stem cell therapy and medical history.
The study will benefit the scientists in understanding how they can control the future of stem cells by modifying the cell chemical environment. This technique of controlling the differentiation of stem cells will avoid the modification of genetic make –up of a cell that might make the cell cancerous. Dr. Lee said that many of the scientists have this belief that protein and the chemical signaling system possess some specific functions. However, this study demonstrates that one signal can be modified giving different instructions.
The benefits of stem cells study would be that it will further pave the way for higher research and studies in the generation of cells and tissue repairing. It can be used in the personalized medicine in which stem cells taken from a single patient are manipulated for making other cell types that match genetically to the donor. Urban Lendahl is the vice-chairman and also professor of genetics at the Karolinska Institutet in Sweden at the department of Cell and Molecular Biology. He has said that, “this study by Dr. Lee has truly given advanced findings that have added much to our knowledge regarding this field”.
