Rules coming for stem cell products, use

Biotech requires quality controls beyond normal drugs, experts say

China plans to set a dozen quality-control standards for stem cell therapies to encourage innovation in the booming sector, medical researchers and health authorities said.

In February, the Chinese Society for Cell Biology issued a new set of standards explaining the basic qualities of human embryonic stem cells - which can develop into a variety of tissue types - laying out technical guidelines for quality control and the requirements for product use.
