Growing new organs (and tissues)

You already know that scientists can grow tissues in the lab and physicians can transplant them successfully into living bodies, right?

A recent article in Scientific American brings us up to date on the rapidly progressing area of tissue and organ "farming."

Besides keeping us A&P professors up to speed on the latest practical applications of "why we need to know this stuff," the article does a great job of illustrating some of the core physiological and anatomical principles that affect such applications. For example, the article talks about the various concepts related to stem cells and development, as well as how the microenvironment of tissues affects their growth and development.
