AlOLanamr Fanning, Saturday, April 11, 1988 OPINION The Future of Agriculture It was reported by the Associated Press last week that an exper iment with genetically engineered animal heart cells indicates that science one day may learn how to replace damaged cardiac muscle with new tissue after a heart attack. The study in the Proceedings of the National Academy of Sci ences demonstrates for the first time that mammal heart cells can be genetically engineered to grow and reproduce endlessly in a test tube. Dr. William C. Claycomb of Louisiana State University Medical Center says that his lab also was able to show that geneti cally altered mouse heart cells could survive and beat like normal heart muscle cells when placed into the damaged heart of a pig. To predict what role agriculture will play in the genetic engi neering sciences of the future is beyond our ability. Who would have thought 10 years ago that dairy fanners would be willing to pay over $7,000 for a pick of transplanted embryos six month in advance of birth at the state Holstein sale. Yet, ET cattle and the process of collecting embryos from the best cows is now quite common and even financially within the reach of most dairy farmers. Then we have genetically engineered com and other grains. And we have cloned sheep and dairy cattle. Even now you can imagine that someday, maybe soon, you will call your genetic engineer and order replacement parts for your best bovine speci men the same as you would order a part for a disabled tractor or piece of farm machinery. We can wish the agriculture of the future to be the same as we know it today. But wishing will not make it so. More likely, with in the lifetime of our grandchildren, they will look back on our generation and remember antiquated things as we do when our grandpa replaced one of his teams of mules with a Farmall A tractor.
