Prions, proteins that can convert between structurally and functionally distinct states and serve as non-Mendelian mechanisms of inheritance, were initially discovered and only known in eukaryotes, and consequently considered to likely be a relatively late evolutionary acquisition. However, the recent discovery of prions in bacteria and viruses has...
Prions, proteins that can convert between structurally and functionally distinct states and serve as non-Mendelian mechanisms of inheritance, were initially discovered and only known in eukaryotes, and consequently considered to likely be a relatively late evolutionary acquisition.

Prions are proteins capable of acquiring an alternate conformation that can then induce additional copies to adopt this same alternate conformation. Although initially discovered in relation to mammalian disease, subsequent studies have revealed the presence of prions in Bacteria and Viruses, suggesting an ancient evolutionary origin. Here we explo...
Human space exploration and settlement will require leaps forward in life support for environmental management and healthcare. Life support systems must efficiently use nonrenewable resources packed from Earth while increasingly relying on resources available locally in space. On-demand production of components and materials (e.g., 3D printing and...
In situ resource utilization (ISRU) increasingly features as an element of human long-term exploration and settlement missions to the lunar surface. In this study, all requirements to test a novel, biological approach for ISRU are validated, and an end-to-end mission architecture is proposed. The general mission consists of a lander with a fully au...
NASA’s Technology Roadmap calls for “innovative physical manufacturing processes to combine the ‘digital thread’ that integrates modern design and manufacturing”. A technology demonstration by Made in Space, Inc, proved the reliability of 3D printing in low Earth orbit. The geometric tolerance and mechanical performance of parts 3D printed aboard t...
Purpose
This paper aims to present a solid freeform fabrication-based in situ three-dimensional (3D) printing method. This method enables simultaneous cross-linking alginate at ambient environmental conditions (temperature and pressure) for 3D-laden construct fabrication. The fabrication feasibility and potentials in biomedical applications were ev...
Bottom-up tissue engineering requires methodological progress of biofabrication to capture key design facets of anatomical arrangements across micro, meso and macro-scales. The diffusive mass transfer properties necessary to elicit stability and functionality require hetero-typic contact, cell-to-cell signaling and uniform nutrient diffusion. Biopr...
This topical review with original analysis and empirical results compares cell sensitivity to physical stress during printing. The objective is to frame a reproducible causation between printing environment and printed cell morphology, viability and phenotype stability. Content includes: (1) a topical review classifies the overlap between physical...
A PED (precision extrusion deposition)/replica molding process enables scaffold guided tissue engineering of a heterocellular microfluidic device. We investigate two types of cell-laden devices: the first with a 3D microfluidic manifold fully embedded in a PDMS (polydimethylsiloxane) substrate and the second a channel network on the surface of the...
Surface properties of biopolymers are crucial for providing topographical and chemical cues to affect cellular behaviors, such as attachment, spreading, viability, proliferation, and differentiation. As an effective surface modification technique, plasma treatment is often applied to enhance surface wettability, adhesion, and biocompatibility of po...
The utilization of the microfabrication technique to fabricate advanced computing chips has exponentially increased in the last few decades. Needless to say, this fabrication technique offers some unique advantages to develop micro-systems. Though many conventional microfabrication techniques today uses very harsh chemicals, the authors believe tha...
Advances in micro-electro-mechanical systems (MEMS) have led to an increased fabrication of micro-channels. Microfabrication techniques are utilized to develop microfluidic channels for continuous nutrition supply to cells inside a micro-environment. The ability of cells to build tissues and maintain tissue-specific functions depends on the interac...
Written by world-leading experts, this book focusses on the role of biomaterials in stem cell research and regenerative medicine. Emphasising basic principles and methodology, it covers stem cell interactions, fabrication technologies, design principles, physical characterisation and biological evaluation, across a broad variety of systems and biom...
Micro-electromechanical systems (MEMS) technologies illustrate the potential for many applications in the field of tissue engineering, regenerative medicine, and life sciences. The fabrication of tissue models integrates the multidisciplinary field of life sciences and engineering. Presently, monolayer cell cultures are frequently used to investiga...
Three-dimensional tissue platforms are rapidly becoming the method of choice for quantification of the heterogeneity of cell populations for many diagnostic and drug therapy applications. Microfluidic sensors and the integration of sensors with microfluidic systems are often described as miniature versions of their macro-scale counterparts. This te...
An engineered three-dimensional scaffold with hierarchical porosity and multiple niche microenvironments is produced using a combined multi-nozzle deposition-freeze casting technique. In this paper we present a process to fabricate a scaffold with improved interconnectivity and hierarchical porosity. The scaffold is produced using a two-stage manuf...
Micro-electro-mechanical systems (MEMS) have revolutionized computation power due to their capabilities to develop advanced micro-architectures. MEMS technologies illustrate the potential for many applications in the field of tissue engineering, regenerative medicine, and life sciences. The fabrication of tissue models integrates the multidisciplin...
In the field of tissue engineering, regenerative medicine, and life sciences, the topological biochemical cues regulate cell attachment and alignment within the construct. In a native biological system, these cues are inherent. However, most of the biological materials utilized in the fabrication of tissue construct do not possess the appropriate c...
The objective of this work is to produce a 3-dimensional scaffold with hierarchical porosity produced with automated manufacturing control. In this paper we present a two-step manufacturing process: solid freeform fabrication (SFF) of a polymer scaffold, followed by freeze casting, a directional solidification technique, of composite slurry. This c...
A maskless microplasma surface patterning system for biologics printing has been developed. The novel system integration includes a low-temperature atmospheric plasma jet and a multi-nozzle freeform biomolecule printing apparatus. Microplasma surface patterning was applied on polystyrene and characterized biologically.
3-Dimensional hepatocyte aggregates experience simulated microgravity in a Rotary Cell Culture System (RCCS). Pharmacokinetic rate and urea secretion are up-regulated in model microgravity.
