Researchers have succeeded in linking together artificial cells, paving the way for new types of chemical catalysts and drug delivery systems.. In a paper published in the journal Nature Communications, a team headed by Yuval Elani from Imperial College London in the UK reports successfully inducing cell-sized double-layered fluid-filled compartments to link up with each other, thus solving one of the key performance issues with artificial cell technologies.. Artificial cell membranes usually bounce off each other like rubber balls, says Elani. By altering the biophysics of the membranes in our cells, we got them instead to stick to each other like stickle bricks.{%recommended 7042%}. Getting the cells to adhere to each other is important, because the resulting shapes - and the connections between them - potentially allow a wide range of uses, including the development of a new smart biomaterials. Artificial cells are considered valuable basic building blocks in the emerging field of ...
Microgels as Artificial Cells. AIM. Design and optimize microgels with cell-like properties to advance 3D cell culture studies.. INTRODUCTION. Culturing cells in aggregates is a very efficient approach to study their interactions in a natural 3D environment. However, complete understanding of cell-cell interactions in cellular co-cultures has not yet been achieved. We hypothesize that artificial cells made from small hydrogel beads (i.e., microgels) could play a significant role in gaining deeper understanding of cellular interactions. Specifically, we aim to engineer microgels with the size and certain functions of natural cells. Custom modifications of these artificial cells would enables the controlled study of specific interactions within 3D cell aggregates.. Recently, our group has developed a microfluidic platform for the production of cell adhesive microgels that can be incorporated in cell aggregates.[1] We have demonstrated that these cell/gel microcultures can be cultured for several ...
Liposomes have been used as artificial cell models to understand cell shape, membrane protein function, and lipid−protein interaction, among other biological functions (1⇓-3). In addition, liposomes have been used as a platform for biosensing and as drug delivery systems (DDS) because of their excellent biocompatibility and biodegradability (4). However, liposomes collapse easily against environmental shifts and mechanical forces because of their low bending modulus. The fragility of liposomes causes uncontrolled leakage of the entrapped compounds and thus inhibits their use in biomedical applications and artificial cells experiments.. In contrast, cell membranes are tolerant against environmental shifts and mechanical forces. The stability of cell membrane arises from the cytoskeleton underneath the membrane. The major component of cytoskeletons is actin (5). Actin gels show high elasticity (6), which ensures the stability of cell membranes against various forces. For liposomes, the use of ...
The success of life on earth is based on the amazing ability of living cells to divide themselves into two daughter cells. During such a division process, the outer cell membrane has to undergo a series of morphological transformations that ultimately lead to membrane fission. Scientists at the Max Planck Institute of Colloids and Interfaces, Potsdam, and at the Max Planck Institute for Polymer Research, Mainz, have now achieved unprecedented control over these shape transformations and the resulting division process by anchoring low densities of proteins to the artificial cell membranes. [Nature Communications 11, 905 (2020) DOI 10.1038/s41467-020-14696-0]. All living organisms on earth are built up from individual cells. Furthermore, the proliferation and growth of these organisms is based on the ability of each cell to divide into two daughter cells.

Chemists have taken an important step in making artificial life forms from scratch. Using a novel chemical reaction, they have created self-assembling cell membranes, the structural envelopes that contain and support the reactions required for life.. Neal Devaraj, assistant professor of chemistry at the University of California, San Diego, and Itay Budin, a graduate student at Harvard University, report their success in the Journal of the American Chemical Society.. One of our long term, very ambitious goals is to try to make an artificial cell, a synthetic living unit from the bottom up - to make a living organism from non-living molecules that have never been through or touched a living organism, Devaraj said. Presumably this occurred at some point in the past. Otherwise life wouldnt exist.. By assembling an essential component of earthly life with no biological precursors, they hope to illuminate lifes origins.. We dont understand this really fundamental step in our existence, which ...

Newly formed protocell. Image 2 of 5. Artwork showing cellular components inside a basic cell membrane. This protocell (artificial cell) was formed from a synthetic primeval soup containing PNA (peptide nucleic acid, orange), fatty acids (blue) and lysosomes (enzyme-producing organelles, yellow). The primeval soup was a mix of carbon based molecules that chemically evolved to form simple cells, at the beginning of life. Scientists at Los Alamos National Laboratory in New Mexico, USA, attempted to recreate this in 2006 by making protocells. Here, the loose components have arranged themselves into an ordered structure resembling a simple cell. See G200/112-G200/116 for a series of images showing the creation of a protocell. - Stock Image G200/0113

Caltech Engineering and Applied Science faculty work at the edges of fundamental science to invent the technologies of the future.
In recent years there has been an increasing interest in using lipid vesicles and related membrane structures as (i) artificial cells that mimic biological processes and (ii) bio-inspired micro-machines that serve functional purposes. To date, vesicles have largely been single-compartment structures with homogenous interiors, which has impeded the fulfilment of these goals. This thesis details the development of technologies to address this. We develop droplet-based methods to controllably generate multi-compartment vesicles (MCVs) for the first time. The potential of these novel structures as artificial cells capable of hosting a range of biological and bio-mimetic processes is explored. Most notably, we introduce spatial segregation of function, thus mimicking eukaryotic organelles, and incorporate an artificial enzymatic signalling cascade to transmit chemical signals between distinct vesicle regions. We also construct microfluidic devices to generate related structures known as multisomes. ...

Beginning with an artificial membrane composed of a bilayer of phopholipids (similar to the lipid bilayers that form the membranes of living cells), the team created shuttle molecules that were soluble inside the lipid layer of the membrane, but not in the water inside and outside the cell. These molecules, through the addition or removal of electrons, bind calcium ions at the outside surface of the liposome (these ions are water soluble and not ordinarily able to enter the oily lipid environment of the membrane), take them across the membrane, and release them at the membrane s inner surface. The ions, which cannot remain in the lipid environment, go to the water solution inside the cell, raising its concentration of calcium ions ...

How did life originate? And can scientists create life? These questions not only occupy the minds of scientists interested in the origin of life, but also researchers working with technology of the future.. If we can create artificial living systems, we may not only understand the origin of life - we can also revolutionize the future of technology.. Protocells are the simplest, most primitive living systems, you can think of. The oldest ancestor of life on Earth was a protocell, and when we see, what it eventually managed to evolve into, we understand why science is so fascinated with protocells. If science can create an artificial protocell, we get a very basic ingredient for creating more advanced artificial life.. However, creating an artificial protocell is far from simple, and so far no one has managed to do that. One of the challenges is to create the information strings that can be inherited by cell offspring, including protocells. Such information strings are like modern DNA or RNA ...

Over the past few decades, biological research has vastly improved our understanding of life processes at the molecular, organismal and community levels. In recent years, researchers have been able to use this knowledge base and the toolkits of synthetic biology and cellular engineering to address fundamental biological questions. Synthetic biologists and cellular engineers have also been able to repurpose organisms and organismal processes to address important problems in health, manufacturing, energy, ecology and agriculture, profoundly impacting the bioeconomy. With recent technological advances such as the ability to assemble cell-like systems with particular functionalities and the ability to make precision small-scale and large-scale modifications to eukaryotic and prokaryotic genomes using rewriting tools, synthetic biology is poised to enter the age of designer organelles, cell-like systems and organisms. Indeed, progress in rational cell design technology will enable synthetic biology ...
TY - JOUR. T1 - Collaboration between primitive cell membranes and soluble catalysts. AU - Adamala, Katarzyna P.. AU - Engelhart, Aaron E.. AU - Szostak, Jack W.. PY - 2016/3/21. Y1 - 2016/3/21. N2 - One widely held model of early life suggests primitive cells consisted of simple RNA-based catalysts within lipid compartments. One possible selective advantage conferred by an encapsulated catalyst is stabilization of the compartment, resulting from catalyst-promoted synthesis of key membrane components. Here we show model protocell vesicles containing an encapsulated enzyme that promotes the synthesis of simple fatty acid derivatives become stabilized to Mg 2+, which is required for ribozyme activity and RNA synthesis. Thus, protocells capable of such catalytic transformations would have enjoyed a selective advantage over other protocells in high Mg 2+ environments. The synthetic transformation requires both the catalyst and vesicles that solubilize the water-insoluble precursor lipid. We suggest ...
Proto-cells are much less complex than natural cells. One important element in natural cells that scientists have not yet been able to integrate in their synthetic counterparts is the so-called glycocalyx, which consists mainly of polysaccharides. It protects the cell membrane and also plays an important role in the interaction between cells, among other things. Lectins, which are proteins that can bind sugar, are also important for cellular interaction.. Some pathogens, like viruses and bacteria, use sugar-protein interaction to enter human cells. Sugar-protein interaction can also cause the formation of proto-organelles and proto-tissues. That is why Römers team is investigating not only the integration of components in giant vesicles, but also interaction within the proto-cell with the help of fluorescence and atomic force microscopes. The teams goal is to build proto-organelles and proto-tissues.. The ERASynBio project provides funding for synthetic biology by structuring and coordinating ...

For cellular organisms, the transport of specific molecules across compartmentalizing membrane barriers is essential in order to exchange content with their environment and with other individuals. For example, content exchange between individuals enables horizontal gene transfer, an important factor in the evolution of cellular life.[30] While modern cells can rely on complicated protein machineries to catalyze these crucial processes, protocells must have accomplished this using more simple mechanisms. Protocells composed of fatty acids[31] would have been able to easily exchange small molecules and ions with their environment.[1] Membranes consisting of fatty acids have a relatively high permeability to molecules such as nucleoside monophosphate (NMP), nucleoside diphosphate (NDP), and nucleoside triphosphate (NTP), and may withstand millimolar concentrations of Mg2+.[32] Osmotic pressure can also play a significant role regarding this passive membrane transport.[1] Environmental effects have ...

Spinal cord injury (SCI) is a debilitating condition that affects young adults between the ages of 16 and 30, which leads to lifelong medical and financial burdens. SCI still results in a decreased quality-of-life and lower life expectancy for patients. This is due in part to the lack of a regenerative-based therapeutic approach to treating SCI in the clinic.

Our droplet hydrogel bilayer system is an artificial bilayer system for interrogating membrane proteins, but it also allows us to explore new forms of synthetic biology where we can add individual protein function to a droplet, such as touch sensitivity or light sensitivity.. Using a novel DNA origami structure we can protect and controllably release our blocking DNA structures, known as DNA caltrops, to regulate the insertion of membrane proteins into these droplets. This allows us to trigger each functionality, on demand, using a small DNA ligand which removes the DNA caltrop from the proteoliposome.. We are looking for Honours or PhD students who have an interest in DNA origami design, synthetic biology, and artificial cells to learn across the interface of engineering and biology.. ...
The lipid vesicles that this produces are mechanically and chemically stable, allowing us to inject proteins into them, as in natural cells, says Joachim Spatz from the Max Planck Institute for Medical Research in Heidelberg. Using a picoinjection system specially developed for this purpose, the researchers could inject precisely controlled quantities of cellular proteins into the polymer-lipid vesicles. Using this technique, we are able to populate up to 1000 vesicles per second with proteins - cytoskeletal proteins like actin and tubulin or the transmembrane protein integrin. This means we can quickly obtain enough vesicles for biological or medical analysis, explains Spatz. The scientists then remove the surfactant shell and transfer the lipid vesicles to an aqueous solution. The vesicles can, for example, then be made to interact with natural cells.. The new technique is not just limited to helping develop artificial cells, as is the goal of synthetic biology and in Germany the MaxSynBio ...
Our interests lie in constructing minimal systems, or artificial cells, as a tool to understand and recreate certain cellular behaviors.

Grant Number: JPMJER1101.

All living cells use membranes to define physical boundaries and control the movement of biomolecules. Movement of molecules through membranes is a primary means of sending signals to and from cells.. Neal Devaraj, a chemistry and biochemistry professor at UC San Diego, leads a research team that develops and explores new reactions that can trigger the formation of membranes, particularly the spheres that characterize membranes that enclose vesicles and cells.. The new process they have just described is specific and non-toxic, and can be used in the presence of biomolecules one might want to study within artificial cells. The technique could also be used to assemble packets for drug delivery.. Natural cells use enzymes to catalyze the biochemical reactions that manufacture their membranes from thioester precursors, but in this case Devarajs team was able to get membranes to assemble spontaneously, without enzymes, through a process called native chemical ligation.. This is the first report to ...

As the researchers report in an advance online publication by the journal Nature Nanotechnology, these findings may help explain how cells have adapted to the phenomenon of molecular crowding, which has been preserved through evolution. And this understanding may guide synthetic biologists as they develop artificial cells that might someday be used for drug delivery, biofuel production and biosensors.. Cheemeng Tan, a Lane Postdoctoral Fellow and a Branco Weiss Fellow in the Lane Center for Computational Biology, said crowding in a cell isnt so different from a crowd of people. If only a few people are in a room, its easy for people to mingle or even to become isolated. But in a crowded room where its hard to move around, individuals often will tend to stay close to each other for extended periods. Tan, who led the study, said the same thing happens in a cell. If the intracellular space is crowded, binding between molecules increases. ...
Active systems are driven by nonthermal, energy-consuming processes that lead to very rich collective behavior (1-4). Examples are found from macroscopic length scales (fish and birds) to microscopic length scales (bacteria and algae) to even subcellular structures like the cells cytoskeleton. The cytoskeleton is composed of filaments that are dynamically interconnected by passive and active cross-linkers. It provides mechanical stability to biological cells, acts as a force-generating element, and serves as a track network for active intracellular transport (5, 6). Moreover, its dynamics generates internal motion of the cytoplasm that secures nutrient availability and the distribution of organelles (7). Fundamental knowledge about the relationship between cytoskeleton structure and dynamics and about the molecular driving forces helps to obtain a deeper understanding of cellular function and dysfunction in vivo and to design active gel materials, e.g., artificial cells (8) in vitro. ...
The slime mould Dictyostelium discoideum is an excellent microorganism that allows, as a model system, to study many biological problems, such as chemotaxis, gene expression, adhesion, cell differentiation, cell sorting, multicellular development from single cells, intercellular communication, phagocytosis, motility, programmed cell death and signal transduction. However, the microorganism is also investigated by physicists because of its non-linear dynamic behaviour and pattern formation. These single-celled soil inhabitants are an ideal example for the researchers seeking models of artificial cells and chemical robots or researchers in the swarm robotics field ...
It has been hypothesized that heteromers of adenosine A2A receptors (A2AR) and cannabinoid CB1 receptors (CB1R) localized in glutamatergic nerve terminals mediate the integration of adenosine and endocannabinoid signaling involved in the modulation of striatal excitatory neurotransmission. Previous studies have demonstrated the existence of A2AR-CB1R heteromers in artificial cell systems. A dependence of A2AR signaling for the Gi protein-mediated CB1R signaling was described as one of its main biochemical characteristics. However, recent studies have questioned the localization of functionally significant A2AR-CB1R heteromers in striatal glutamatergic terminals. Using a peptide-interfering approach combined with biophysical and biochemical techniques in mammalian transfected cells and computational modeling, we could establish a tetrameric quaternary structure of the A2AR-CB1R heterotetramer. This quaternary structure was different to the also tetrameric structure of heteromers of A2AR with adenosine A1
Abstract: Droplet interface bilayers are a convenient model system to study the physio-chemical properties of phospholipid bilayers, the major component of the cell membrane. The mechanical response of these bilayers to various external mechanical stimuli is an active area of research due to implications for cellular viability and development of artificial cells. In this manuscript we characterize the separation mechanics of droplet interface bilayers under step strain using a combination of experiments and numerical modeling. Initially, we show that the bilayer surface energy can be obtained using principles of energy conservation. Subsequently, we subject the system to a step strain by separating the drops in a step wise manner, and track the evolution of the bilayer contact angle and radius. The relaxation time of the bilayer contact angle and radius, along with the decay magnitude of the bilayer radius were observed to increase with each separation step. By analyzing the forces acting on the ...
A liposome has an aqueous solution core surrounded by a hydrophobic membrane, in the form of a lipid bilayer; hydrophilic solutes dissolved in the core cannot readily pass through the bilayer. Hydrophobic chemicals associate with the bilayer. A liposome can be hence loaded with hydrophobic and/or hydrophilic molecules. To deliver the molecules to a site of action, the lipid bilayer can fuse with other bilayers such as the cell membrane, thus delivering the liposome contents; this is a complex and non-spontaneous event, however.[13] By preparing liposomes in a solution of DNA or drugs (which would normally be unable to diffuse through the membrane) they can be (indiscriminately) delivered past the lipid bilayer, but are then typically distributed non-homogeneously.[14]. Liposomes are used as models for artificial cells. Liposomes can also be designed to deliver drugs in other ways. Liposomes that contain low (or high) pH can be constructed such that dissolved aqueous drugs will be charged in ...
Startling discoveries in the areas of genomics, biotechnology, and nanotechnology are occurring every day. The rewards of this research, some of it as spectacular as what was once thought of as science fiction, are practically in our grasp. Already it is possible to analyze our individual genetic makeups and evaluate our predisposition for breast cancer or other deadly diseases on a case-by-case basis. And once weve isolated these genes, the ability to repress or enhance them through biotechnology is just around the corner. Soon, for example, it will be feasible for 10% of our red blood cells to be replaced by artificial cells, radically extending our life expectancy and enhancing our physical and even mental abilities beyond what is humanly possible today. In Fantastic Voyage, Ray Kurzweil and Terry Grossman will show us how amazingly advanced we are in our medical technology, and how incredibly far each of us can go toward living as long as we dare imagine ...
