INTRODUCTION An important aspect of any biotechnological processes is the culture of animal cells in artificial media. These animal cells in culture are used in recombinant DNA technology‚ genetic manipulations and in a variety of industrial processes. Now-a -days it has become possible to use the cell and tissue culture in the areas of research which have a potential for economic value and commercialization. The animal cell cultures are being extensively used in production of vaccines‚ monoclonal antibodies

After reading the “‘Bubble baby’ stem cell” paper I have come to the conclusion that stem cell research is an excellent thing. The reason why I think that is if we never do research and create a cure for “Bubble baby disease” then we will continue to lose babies. But‚ if we risk a few lives of babies for research in the long run it will save millions if not billions of lives. In this essay I will give three reasons on why I think stem cell research is a great thing. “Bubble baby disease.” In my
