Image: ©2001 MacMillan Publishers Ltd.  PLURIPOTENT-CELL PIPELINE: To obtain embryonic germ cells, researchers culture primordial germ cells (PGCs) dissected from the genital ridge. If left in situ, a PGC develops into spermatozoa or ova after its imprints have been erased and reestablished. Embryonic stem cells come from the blastocyst's inner cell mass. (Reprinted with permission, Nature 414:122-8, 2001) Because the science is hard and the politics mean, progress in understanding

Date: June 22, 1998 Insect Cell Culture Media, Suppliers of Primary Cell Culture Media Advantages for Protein Expression Studies Since the mid-1950s cultures of insects--cockroaches, fruit flies, and leafhoppers, to name a few--have been the object of quiet study by physiologists and cell biologists. But along came genetic engineering and suddenly insect cultures have been put in the spotlight since they provide advantages over both bacterial and mammalian systems for recombinant protein prod
