IDK. Looking at that wikipedia article, the progress looks pretty good.
Also, just on a conceptual level, growing a whole embryo may be a lot easier than growing a single organ. Organs really aren’t designed to grow by themselves. A fetus is designed to grow and develop. It needs a nutrient supply.
But I think of it as the difference between trying to figure out how to grow plants in aquaponics vs trying to somehow coax plant cells to grow a flower without the rest of the flower plant present.
