Cloning a Trachea

In the news there is a story about a man from Eritrea going to school in Iceland recovering from surgery in Sweden where a surgeon born in Italy recently gave him a new trachea grown in a bioreactor from the United States composed of synthetic scaffold designed in the United Kingdom and the man's own stem cells! The world is certainly getting smaller and the smaller it gets the more specialists like surgeon Paolo Macchiarini and others can collaborate to make stories like this possible. I'm posting this because it's a relevant update to a blog entry I made recently on Cloning.

Cloning

I recently read about a survey that shows Americans are more accepting of cloned food than Europeans. Right now we are on the cusp of a new era. Today, the practice of cloning is limited to a small number of labs around the world. Tomorrow, cloning of livestock, pets, and even people could be commonplace.

There are several advantages and disadvantages of cloned livestock. Most obviously, farmers can clone the most desirable animals for leanness, milk production, taste, and so on. Farmers could also select clones that are resistant to certain strains of disease. However, this lack of genetic diversity could leave the industry open to other diseases (read here for more). There is also evidence that cloned animals suffer more liver and kidney aliments, die younger, and reach puberty later (RSPCA).
