Why the use of cartilage?

That is a good question. What could be the rationale for shark cartilage extract to cause anti-angiogenic effects? I found the following suggestion at the website of the Kidney Cancer Association.

A unique characteristic of cartilage is the absence of nerves or blood vessels. Studies have found that cartilage contains more naturally occurring angiogenesis inhibitors than molecules that activate angiogenesis, which may account for the absence of blood vessels in cartilage. Sharks are a good source of cartilage because cartilage contributes up to 6% to 8% of their total body weight. In mammals, cartilage makes up less than 1% of total body weight. Aeterna uses cartilage from the most common species of shark called the dogfish. It has contracted with fishermen in various parts of the world (who normally fish that type of shark for food) to collect the cartilage that would otherwise be thrown away.
