Are there any organs that we haven't been able to make artificially ?

I know the human body is INCREDIBLY complex, but if there are organs we are unable to make artificially, why are we not able to do so?

    Virtually all of them.  They've been able to make a bladder artificially but that's about all so far other than heart valves and bits of metal nailed in place of bones.  Stem cell research looks promising but a major problem is that gravity makes it difficult to create three dimensional shapes from them, they tend to end up with a puddle of cells instead.  Some research has been done in space but that's not going to supply all the organs they need.

    Mainly because we have no idea how to make a system of bloodvessels good enough to keep all the cells of the entire organ alive.

    What we can do is grow *sheets* of cells in a nourishing liquid, an if you roll up a sheet you get a *tube*.

    So tubes and very flat pieces of tissue can be grown from your own cells, but that's about it
