"This is certainly something we pay attention to," Ai Lixin said.

Everyone is concerned with the issue of lifespan, and most people hope to live a little longer. Research related to life extension has always been a focal point, and the progress the laboratory has made to this point includes a great deal of economic interest.

For instance, some wealthy individuals might hope to receive injections of a few life-extending proteins and enzymes.

This is bound to happen.

However, it is not easy to extract specific proteins and enzymes.

Ai Lixin spoke about this issue, "We originally wanted to extract more, but it's tough because the materials are severely lacking."

"For general mammals, including pigs, sheep, and cattle, extractions can only be done from blood and hematopoietic stem cells, but the content is very small."

"For each experiment, we need to use a lot of blood, and the process is very complex, consuming a great deal of resources."
