Ask HN: food replicator possible?

I want to know when we think a food replicator would be possible that can grow organic food products from stemcells.

Are there the equivalent of stemcells from plants as well as from tissue based organisms that would allow for the growth of plant matter based foods in addition to meat/protein.

I was thinkijg that a similar device would be required for travel to other Planets such as mars.

All ethics and squemishness aside, is a stemcell based food replication unit possible, and if so, how far off are we.
