The benefits of 3D cell culture

The development of lifelike 3D bone environments represents a good example of how 3D printing technology is revolutionizing the future of medicine, yielding advances in biotechnology and drug development. Especially, with the capacity to overcome the shortcomings and drawbacks of conventional 2D cellular models and animal models, 3D cell cultures show huge potential in regenerative medicine and disease modeling.

Until now, drug screening has primarily been performed via 2D cell lines or in animal models, typically performed in mice. In vivo animal testing is currently required to document the safety and efficacy of a treatment in a living organism. However, animal models are time- and resource intensive and are not always a reliable way to predict how drug treatments will affect humans. Meanwhile, the traditional two-dimensional cell culture models, widely used for laboratory (in vitro) research, do not accurately mimic the cellular environments of human organs or physiology. Namely, because the cells in our body do not grow flat in a monolayer.

3D cellular models, on the other hand, yield better and more reliable research models as they maintain the cell-to-cell interaction as well as the cell-to-matrix interaction.
Accordingly, one disruptive driver of switching to 3D techniques from conventional methods is the possible reduction in researchers’ reliance on in vivo animal models to obtain relevant data. Reducing the use of in vivo animal models, owing to the relevant and predictive data from 3D cellular models, may consequently reduce the costs and time needed to get new human therapeutics into the clinic.


3D cellular models may improve input in bone cancer pathology

Bone cancer is one of a wide variety of diseases that can affect our bones. Yet, a good model to understand the pathology of primary bone cancer has been lacking. In cancer drug screening, 2D monolayer cell cultures do not successfully mimic the histoarchitecture of the primary bone cancer or the genetic landscape of the bone tumor.

Three-dimensional cell cultures provide a more accurate replica of the bone composition and stiffness of the human tissue. This, in consequence, facilitates a more realistic growth and enables a better understanding of the complex biology in a physiologically relevant context.

The 3D scaffolds can further be used to create excellent disease models, such as bone tumors. By mimicking the in vivo environment of tumors and the interplay between the tumor and the host environment, 3D cell culture models allow for accurate assessments of the efficacy of drug candidates in cancer patients.
Such an advancement in the accuracy of in vitro research is of great importance since it allows researchers to succeed or fail faster than they do with 2D cultures, thereby increasing the effectiveness of their research. 



Bringing natural bone environments to the lab

Particle3D’s scaffolds are unique bone environments made from β-tricalcium phosphate using a proprietary 3D printing process. Owing to the unique structures which are 3D printed with internal porosities to mimic the porous structure observed in human bones, P3D Scaffolds are very reliable research models for disease modeling and regenerative medicine that yield more relevant and accurate cellular environment investigations.
