We don’t even know what like, 20% of the genes do. Simulations are neat, but they miss a lot of underlying biology that actually makes an impact on engineering. One of my favorite papers was published 40 years ago on this topic https://pitp.ias.edu/sites/pitp/files/morowitz-completeness_...

If you read the article you'd know that that's exactly why organisms such as JCVI-syn3A were created, where we know the (or at least some) function of 80% of the genes.

Oh wow, a RISC (reduced instruction set cell).

I thought you posted “Can a biologist fix a radio?” It’s also very pertinent to this topic:

Interesting blog post, based on an interesting paper.

For a bit more background, there's been a couple of posts on the "minimal cell" concept on Derek Lowe's venerable In the Pipeline blog. This 2016 post [1] talks about the initial development of the JCVI-syn3.0 cell; this 2023 post [2] goes over a paper that studied the evolutionary dynamics of these minimal cells.

Fascinating stuff, thanks! A recent workshop with recorded talks on such cells https://www.jcvi.org/events/minimal-cell-workshop I am wondering if other researchers can procure or produce these cells or these are rather a know-how of JCVI?

I gave a talk at that workshop! (I’m making the 61 codon version of JCVI-Syn3a) You can get the cells as a researcher, but basically forget about it for a commercial user or hobbyist. They’re also annoying as hell to grow. I’m trying to synthesize it from scratch for the precise reason of freeing it from MTAs (material transfer agreements)

Sounds like you're doing good work! Out of curiosity, can you give a layman's explanation of what makes them hard to grow?

I’m well aware. I was in charge of designing and synthesizing the entire gene set, optimized for E.coli, in order for scientists to easily try to discover the function of these genes https://stanford.freegenes.org/collections/gene-sets/product...

Out of the 100 or so unknown genes we had/have, only like 3 unknowns were actually used for research. Such is science sometimes.

Their media is real complicated and expensive (plus difficult to prepare: can’t just throw everything in an autoclave), and they don’t grow very fast, and they don’t grow to a high concentration. Basically that means that you can easily get contamination (like you would growing human cells), and even when you do get growth, it’s dilute.

I wonder if it would be possible to simplify the task further, by removing cell reproduction processes? As far as I understand, an "immortal" non-replicating cell does not exist in nature, but there is nothing that prevents an artificial one from existing, especially if it has ways to repair cellular damage.

Non-replicating cell is called a virus.
