ROKIT Healthcare’s vision for bioprinting:
Bioprinting is not only a revolution that’s underway for the way we create and use model systems for answering basic biological questions; it is revolutionary in the way we practice medicine – instead of using systems that rely on treatments of the symptoms using small molecules or monotherapies, bioprinting shifts focus towards harnessing the body’s own healing potential inherent in the stem cells and 3D human tissue-like microenvironments
Events of November 2020
Bioprinting, with its automated handling, processing and scalability of technology, has made recent advances in creating 3D cancer and microenvironment models with improved results in novel drug testing and development.
In this web mini-symposium, learn from speakers at the front lines of cancer research and bioprinting applications about
- Key morphology and functional differences between 2D and 3D-organized tumor tissues.
- Case studies in tumor tissue and microenvironment modeling & cancer therapy developments.
- Case studies in identifying appropriate biomarkers for early detection and prognosis of cancer.
What is 4D Bioprinting?
4D bioprinting is an additive manufacturing process in which cells, biopolymers and growth factors are combined to create living structures that imitate native human tissues. Because these printed tissues are often further incubated to proliferate, mature and change over time, there is a dimension of time here that makes it 4D instead of 3D. The technology brings key values of automation, biomimetic architecture, and on-demand biomanufacturing and is widely applicable to the fields of bioengineering and medicine, from in vitro applications in novel product screening, disease modeling, and animal alternative methods of experiment to in vivo applications in tissue transplantation and regeneration.
The 4D bioprinting technology consists of largely three components: biomaterials, the bioprinter, and design.
- Biomaterials are bio-compatible and bio-degradable materials that may be derived both from natural and synthetic sources. Naturally-derived biomaterials include collagen, gelatin, elastin, chitin coming from the extracellular matrix of human or animal cells; they can be alginate, sericin, or cellulose coming from seaweed, insects and plants, respectively. Synthetic biomaterials are biodegradable polymers with enough strength and elasticity to apply to human tissues and may have FDA approval as medical device components, i.e. PCL, PLA and PLGA. Natural and synthetic materials can be used in combination to bolster certain mechanical or biochemical properties.
- Bioprinter is the actual hardware that prints tissue structures based on 3D models. There are various methods of bioprinting today, from inkjet based, laser-assisted and stereolithography methods, but extrusion is the most common one used (over 70%). Key functions of the bioprinter are a built-in clean-chamber and bioreactor that could provide UV disinfection, HEPA filer and mammalian cell culture environments to optimize cell viability and functionality during and after the printing process.
- Design refers to the 3D models that the bioprinter would create. Models may be obtained either from manual drawings using a design software or may be derived from CAD/MRI scans of a patient body. These 3D model files then get processed with a slicing software into G-CODE, a standard machine language that will dictate how a 3D printer should print the job in a given three-dimensional space.
The process principally involves five key steps:
- Preparation involves designing the experiment with a clear identification of the problem to address. It includes selection of the right biomaterials, cell types, and 3D models that the printer will use.
- Bioprinting is the actual printing process. 3D models are sliced into appropriate printing instructions. Bioink is placed in a printer cartridge and deposition takes place based on the digital model.
- Post-bioprinting is the mechanical and chemical stimulation of printed parts so as to create stable and functional structures for the biological material.
- Evaluation is the step in which cultured printed tissues are assessed for structural, morphological and functional characterization in comparison with the living tissue standards.
- Application involves making use of the bioprinted products for various purposes, such as disease modeling, in vitro safety and efficacy testing, and in vivo tissue transplantation.
Bioprinting is not only a revolution that’s underway for the way we create and use model systems for answering basic biological questions. It’s also a revolution in the way we practice medicine. Instead of using conventional systems that rely on treatments of the symptoms using small molecules or biologics, bioprinting shifts focus toward harnessing the body’s own healing potential inherent in the stem cells. It enables endogenous tissue regeneration by priming the body’s stem cells with the bioprinted “niche”, consisting of growth factors, biomaterials, and three-dimensional architecture.
In the world of aging populations, the ability to create tissues on demand and offer novel regenerative medicine approaches will be crucial in improving the quality of life.
