FORT COLLINS--Professor Chris Polge, the world-class scientist who pioneered methods for cryopreservation, the technique of preserving live cells so they can be reused, is in Fort Collins through Wednesday.
      Polge's innovative discovery of techniques for cryopreservation of living cells, sperm and embryos prompted the development of the science of cryobiology and worldwide use of frozen sperm and embryos for genetic improvement of livestock.
      Reporters are invited to attend Polge's lecture on the 50-year history of cryopreservation. The 30-minute talk begins at 4:15 p.m. on Wednesday in the seminar room of the Animal Reproduction and Biological Sciences Laboratory on the Foothills Research Campus of Colorado State University.
      Polge also is available for interviews from 12:30 p.m-3 p.m. Wednesday. To schedule an interview, call 970/484-7500.
