Cloning: Pathways to a Pluripotent Future

In this month's article, Anne McLaren describes the entanglement and sagging that connects the early stages of the biological cell theory of the 1930's with the era of newly evolving cloning science and technology. The birth of the Scottish clone sheep Dolly was announced. These possibilities are wonderful, including the possibility of new medical care, and possibly human cloning ... and ethical standards

Research on cloning technology has improved our basic understanding of human developmental biology. Observing cultivated human pluripotent stem cells can gain insight into the development of human embryos, otherwise they will not be seen. Scientists can now better determine the early human development steps. Studying signaling and genetic manipulation in early human embryos has the potential to provide answers to many developmental diseases and defects. Many human-specific signal transduction pathways have been discovered by studying human embryonic stem cells. Studying human developmental pathways further provided evidence to developmental biologists that the developmental pathway is preserved through species.

Studies of developmental pathways in model organisms provide important information on how to isolate, maintain, and differentiate human pluripotent stem cells. However, the details of the developmental pathway are different even for mammalian species. In order to fully achieve the potential of stem cells, more direct studies of human or primate developmental biology will be required.

The influence of developmental biology on pluripotent stem cell research: success and challenge

In this month's article, Anne McLaren describes the entanglement and sagging that connects the early stages of the biological cell theory of the 1930's with the era of newly evolving cloning science and technology.

In science, human cloning has its own advantages and problems, especially therapeutic cloning. One of the main advantages of using stem cells isolated from embryos is that the cells are pluripotent. This means that these cells can differentiate into all kinds of human cells other than embryonic cells. Thus, pluripotent cells have the potential to grow and produce healthy organs by replacing defective cells, or to treat any body (tissue) disease; to prevent cardiovascular disease Damaged heart tissue to do (Explorestemcells, 2010)
