New Techniques
Typically, stem cells have been maintained using tissue culture methods that essentially date from the 1950s. In particular, they are often "fed" using mouse embryonic fibroblasts ("feeder cells") while being simultaneously suspended in a nutrient solution ("media"). However, many scientists are recognizing the importance of using media that is completely free of animal ingredients. This not only liberates cell lines from animal feeder cells, but also brings the in vivo therapeutic use of stem cells one step closer to reality.

Famous quotes containing the word techniques:
“The techniques of opening conversation are universal. I knew long ago and rediscovered that the best way to attract attention, help, and conversation is to be lost. A man who seeing his mother starving to death on a path kicks her in the stomach to clear the way, will cheerfully devote several hours of his time giving wrong directions to a total stranger who claims to be lost.”
—John Steinbeck (1902–1968)
“It is easy to lose confidence in our natural ability to raise children. The true techniques for raising children are simple: Be with them, play with them, talk to them. You are not squandering their time no matter what the latest child development books say about “purposeful play” and “cognitive learning skills.””
—Neil Kurshan (20th century)
