Have you guys even looked at the stuff they accomplished? Literally everything they've been doing is a first with it comes to regenerative medicine.
1) Successfully growing and implanting bladders entirely in the lab.
2) Engineering functional petri dish livers.
3) Engineering and successfully implanting urethras.
4) Engineering penile erectile tissue (no implantation yet)
Besides, If you've done any research you know that nothing materializes overnight in any feild. The fact that they've made any breakthroughs at all is outstanding, let alone the extraordinary breadth of their work.
From their website: "Our scientists were the first in the world to
successfully implant a laboratory-grown organ into humans and today are working to grow more than 30 different organs and tissues in the laboratory."
