3D Bioplotter Research Papers

Bone related diseases and disorders increasingly impact human health. Electrical stimulation (ES) has been shown to promote osteogenesis and healing of bone defects. Graphene, is an electrically conductive and biocompatible material with good mechanical properties (strength with flexibility), and therefore shows significant promise as a cell-compatible electrode for ES. Graphene-based scaffolds may therefore be used for 3D cell and tissue support, including 3D osteoinduction. We have fabricated 3D graphene electrode structures to provide ES to human adipose stem cells (ADSCs). The assemblies support ADSC growth and differentiation, with ES augmenting proliferation and osteogenesis. Our findings expand our previous work on…

3D printing technology is driving innovation in a wide variety of disciplines, and is beginning to make inroads into the fields of medicine and biology. In particular, 3D printing is being increasingly utilized for the design and fabrication of three-dimensional cell culture scaffolds. This technology allows for scaffolds to be produced rapidly while maintaining a great deal of control over the matrix architecture. This paper presents an effective technique for rapidly designing and fabricating scaffolds from silicone rubber and polycaprolactone (PCL), appropriate for primary human cardiomyocyte cell cultures. Additionally, a stimulation device is developed and presented which can provide 6…
