The process involves using the Marine’s stem cells to coat a three-dimensional, surgical-grade silicon “scaffolding” of his nose and placing it in a sterile ovenlike structure that duplicates the warmth and moisture of the human body to incubate for a couple of weeks. Inside the oven, the cells continue to generate and fix themselves over and into the mold. “It’s like baking a cake,” Schoomaker explained.
When that process is complete, “you can plant that (regenerated tissue) back into the same patient, thus avoiding rejection,” Atala said.
Amazing this occurs even though President Bush has outlawed science. /s
