Stem cells is a scientific breakthrough that's revolutionizing the health care industry - Essay Example Major breakthroughs in stem cell research include developing nervous tissue and dealing with spinal cord injuries, Alzheimer’s disease, Parkinson’s disease, and stroke. In fact, stem cell research is a scientific breakthrough thats revolutionizing the health care industry. Since they are derived in the embryonic stages, these stem cells are often called as embryonic stem cells or just ES. The role played by ES in health care industry today is solely dependent on their cultures derived in laboratories. It is well known that stem cell cultures can be maintained and proliferated in the presence of bovine serum. The cultures allow blastomeres or ES cells to be subjected to differential treatment such as nuclear disintegration of cells, nuclear injection into de-nucleated blastomeres and so on to derive the desired tissue. It has been observed that by such differential treatments, the blastomeres differentiate into the tissue of the nucleus donor cells. Thus, any damaged organ of the body can be recreated through ES cultures and differentiation. The main applicability of ES cell research is the creation of fresh organ tissue that can be inserted in the damaged area in the human or animal body to replenish the organ and restore its functions. This has been successfully conducted in treating spinal cord injuries, strokes and functional diseases like Alzheimer’s and Parkinson’s. Yet there is a long way to go. For starters, the biggest limitation of stem cell therapy is that it is restricted to creation of commonly occurring and specific tissue masses and cannot be used to replace or regenerate an entire organ. Therefore, through systematic stem cell culture, the endoderm, mesoderm or ectoderm can be recreated to be replaced in damaged organs, but in no way can an entire organ like a heart be constructed through regenerated tissue sets.
