A Cell Built From Scratch Grows And Divides by nlfpmod(mod): 6:33pm On Jul 01
Scientists say they have built a cell from scratch for the first time

For the First Time, a Cell Built From Scratch Grows and Divides

Scientists built a synthetic cell that combines more lifelike properties than ever before — proof of concept that it’s possible to bring nonliving materials to life, or something close to it, in the lab.

For the very first time, biologists packed nonliving components into a cell-like membrane, piece by piece, and witnessed the bag of molecules start to behave like life. The lab-made synthetic cell grew, replicated its DNA, and divided, demonstrating the basic functions of a cell cycle.

It’s “an impressive step,” said Jack Szostak(opens a new tab), who studies the origins of life at the University of Chicago and was not involved in the research. I don’t know of any other effort to put together an artificial cell from biological components that has progressed so far.

The cell is not alive by any definition. It can’t survive without constant deliveries of food and ribosomes, the machinery needed to make proteins. It has no defenses or a good waste removal system. But it’s the strongest demonstration yet that it is possible to generate life from nonlife, a goal that synthetic biologists have been chasing for decades.

It’s a big step forward to this holy grail of making a living thing out of dead components,” said Sijbren Otto(opens a new tab), a systems chemist at the Stratingh Institute for Chemistry in the Netherlands who was not involved in the work. “It’s not completely there yet, but it’s definitely getting quite close.”

Since these cells were pieced together from scratch, and all the molecular parts were crafted in the lab, scientists can tinker with the system and switch components in and out. “I have a blueprint, I have a full chemical ingredient list of every component,” said Kate Adamala (opens a new tab), a synthetic biologist at the University of Minnesota who led the new study(opens a new tab), which is not yet peer-reviewed. With such flexibility, this kind of synthetic cell could eventually be coaxed to create new materials, such as biofuels and drugs, and help researchers study disease.

It could also give scientists insight into some of their deepest existential questions: What is the minimum needed to sustain life? How could life start? What happens if we alter the biology that composes life on Earth today?

Or, as Adamala put it: “What else can biology do?”

Building Life

Some 4 billion years ago, a bunch of nonliving molecules got together to form the first protocells. They fed, grew, and divided. Then, over time, evolutionary processes emerged that let these cells change and diversify into many different types, decorating a barren world with all manner of strange beings. A purely chemical world blossomed into a biological one. Scientists cannot agree on how this shift from nonlife to life, or abiogenesis, happened, but some have turned their sights on trying it out for themselves in the lab.

For decades, researchers have taken different approaches to this challenge. Some, like the synthetic biologist John Glass(opens a new tab) at the J. Craig Venter Institute, are stripping down bacterial cells to their smallest, barest genomes to reveal a cell’s minimum requirements to stay alive. Others, like Otto, try to build cells with molecules that differ from those found in Earth biology.

Adamala also works from the ground up, but with biological molecules found in nature today. When she started her lab in 2016, she envisioned assembling a synthetic cell, a proof of concept, that could undergo a complete cycle of cell division using its own genome.

She found an instruction manual in what all known cells have in common: They grow, they duplicate their DNA, they divide, and they evolve. They transcribe their DNA into RNA and then make proteins to carry out these tasks and others that keep a cell running, such as metabolizing molecules for energy. All of this is done inside a lipid membrane, which holds all the necessary materials in one place. Adamala’s team needed to build their synthetic cell a genome and supply it with all the materials to carry out those tasks.

They developed and optimized different ingredients, most inspired by other labs, before combining them together inside liposomes — hollow sacs enclosed by a simple lipid membrane. This would serve as the cellular body.

A purely chemical world blossomed into a biological one.

They started with a cell’s most fundamental system: its mechanism for copying its DNA and passing it down to daughter cells. They adopted a DNA replication system(opens a new tab), pioneered by the synthetic biologists Hannes Mutschler(opens a new tab) and Christophe Danelon(opens a new tab), and tweaked it to work alongside other systems, including a commercial pack of 36 enzymes that let the cell read DNA and make proteins. Adamala’s team fiddled with their cellular brew, switching genes in and out and adjusting concentrations of various molecules, to get the crucial information-carrying and protein-making genetic systems to jibe.

Their tiny synthetic genome did not encode any metabolic genes, which would let the cell process food and energy, or many of the complex molecules a cell needs. So, in parallel, the researchers prepped some supply packs.

They filled other liposomes with sugar, lipids, and enzymes, as well as complex molecules, such as transfer RNA (tRNA) and ribosomes, which work together to translate genetic instructions into proteins. For their protocell to accept these crucial supplies, the team also modified a protein that would sit in the cell membrane and attract the lipid bubbles. When a bubble bumped into the cell, their membranes would fuse, releasing the supplies inside.

It wasn’t easy to get all these genetic systems to work together successfully. After some more tweaking and optimizing, the cell started growing and replicating its DNA.

“I was almost ready to say ‘Done’ and ‘We’re going to publish it,’” Adamala recalled. But her vision for a synthetic cell had one more step: division.

Six frames of a green oval-shaped blob on a black background show the sequence as one cell divides into two.

This was where the field had been stuck for some time. Researchers before Adamala had figured out different ways to feed and grow synthetic cells and to replicate their DNA. But cell division is a different beast. A typical cell reorganizes its cytoskeleton — a network of protein fibers that provide structural support — to halve its DNA and split. Synthetic biologists could not figure out how to get their cells to undergo this complex process.

So Adamala decided to ditch the cytoskeleton. One day, while tearing through the literature, she came across an interesting mechanism in a paper(opens a new tab). By attaching protein tags to a cell membrane, the synthetic biologist Reinhard Lipowsky(opens a new tab) at the Max Planck Institute of Colloids and Interfaces attracted other proteins to crowd around and physically bend the membrane, forcing the cell to divide. Following this approach, Adamala tweaked a cell-membrane protein and tested it in her protocells. After several tries, it worked.

“I wasn’t allowing myself to believe it for a while,” she said. “It was like, ‘Holy shit, did I actually make a dividing cell?’ … At some point, you’ve been checking enough that [you think], ‘OK, now it’s real.’”

This paper “beautifully demonstrates this division mechanism,” said Job Boekhoven(opens a new tab), a systems chemist at the Technical University of Munich who was not involved in the study. “That has been a huge achievement.”

By putting together systems inspired by different labs — DNA replication; feeder liposomes; and swarming, division-inducing proteins — and then optimizing them to work together, Adamala’s team showed that it is possible to induce the chemical world to form a biological one in the lab.

“Combining all of these things is a staggering technical accomplishment,” Glass said. “I think it will prove to be a watershed event for the synthetic-cell field and biology in general.”

Michael Lynch(opens a new tab), an evolutionary biologist at Arizona State University who was also not involved in the study, agreed. It is “a synthetic biology tour de force,” he said. However, he also cautioned against over-hyping the cell since it’s not yet self-sustaining.

I think it will prove to be a watershed event for the synthetic-cell field and biology in general.

John Glass, J. Craig Venter Institute

Once the synthetic cells were created, her students and others started calling them Adamala cells — a moniker she hated. She insisted that they name the cells after anything else, jokingly suggesting potatoes. So her students started calling them spudcells. “I’m Polish, I’m mostly made of potatoes, so that’s fine with me,” Adamala said.

Each cell is tiny. Its genome is way smaller than bacterial genomes, and it doesn’t look like anything special. It’s “beautiful to me because I’m super excited about it,” Adamala said. “But if you look at it under the microscope, it’s like, ‘OK, it’s a blob.’”

Evolution and Beyond

The cell could grow and divide. But could it take the next step toward life by evolving?

The researchers started fiddling with the synthetic cell’s DNA to see if they could get some cells to grow larger or divide faster — in effect, creating genetic variation in the cell population. They found that the cells that grew bigger also had more daughter cells and started to become more populous. In other words, those traits started being selected for within the population, the first step toward evolution.

What Adamala’s team demonstrated was not quite natural selection, the primary mechanism that drives evolutionary change, in which organisms that are better adapted to their environment are more likely to survive. Even if she got their cell to produce more daughter cells, she doesn’t think it would lead to evolution. That’s because Adamala’s team had to create genetic variation synthetically, instead of allowing for random mutations in DNA. The enzyme that builds new DNA strands works too well, she said; it doesn’t introduce meaningful mutations into the sequence. They will need to find an enzyme that is more error-prone — but not so error-prone that the genome’s integrity and the cell’s function is lost.

I have always maintained that the anti-christ will be man made and not born. The can already use CRISP-R to genetically edit babies and correct certain abnormalities. I read recently that scientists now can also select for genes that will express desired traits when the child gets born. Selecting for eye colour, height and indeed any desirable physical attributes.
Pretty phenomenal stuff.

Yes na. For instance the DNA of a unliving person can be used to create a carbon copy of that person as an embryo.

That is reincarnation on a higher level.

For now, no negative impact yet.

Invasive species, yes.
Human abuse of technology? Certainly
Creation of undesirable traits? Yes
Gene reset? Probably.
Biological compatibility/rejection? Controversial.

According to Otem's book of Universal History, the things the Homo Erectus built ended them to bring in another set of homos. We are getting there cool We are building what will end us to bring about another set of homos. See what our species used the eyes of the few Neanderthals left to see in those days below.




1. Jugano was a homo sapiens born in the 103,215th year of the homo sapiens era in a land now found in Italy. The name of his father was Lugano.
2. In those days, Jugano left the land of his nativity and went far north. Then he reached a place and settled there.
3. Now the land had very few numbers of the past homo now called homo Neanderthals, who ran for their safety many years ago.
4. These species had multiplied in the land. When they saw Jugano, they took hold of him and tied him.
5. Then Jugano made gestures to them and they let him lose. Then he taught them his own language, because these homos had no language of themselves since they had been separated from their parents from birth.
6. Now when Jugano had lived among them, they loved him greatly and saw him as a god. After five years, some homo sapiens came forcefully to take the land.
7. Then they found the Neanderthals and made war with them. But Jugano led the Neanderthals against his own species and they won the battle.
8. So Jugano married a Neanderthal and had children of mixed species. So the land remained a possession of the Neanderthals all the days of Jugano till his death.
9. And they worshipped him for five centuries until the land was besieged with diseases and natural disasters.
10. Zagugiayu was a male homo sapiens born in the 103,590th year of the homo sapiens era in a land now found in Bolivia.
11. When Zaguguayu spoke against all the gods of his land, saying, Ekeko is a human like us, same as Viracocha and all the other deities we worship, the people of the land rose against him and took him.
12. Ad they said, you have blasphemed the gods and you shall be killed.

In a 1000 - 2000 years there would be very little gap left. Heard this lady discussing this process about abiogenesis - their progress and challenges - on a podcast with NDT late last year, didn't know they were that close. Interesting, guess we should be expecting a massive religious retcon alongside, just like the big bang equals let there be light 😄.
