Akina, Inc. (www.polyscitech.com) has launched a joint
project with additive engineering firm Hatch51 (http://hatch51.com/)
for the creation of a 3D gel-printing system optimized for printing of Akina’s
synthetic thermogelling 3DCellmaker. The printer will allow for low-temperature,
gentle, printing of the thermogelling polymer solution so as to allow for
printing of live-cell loaded solution to form 3D structures and tissues. Such a
system has promise for a wide array of future applications. Those interested in
the hardware portion of the system are encouraged to contact Hatch51 directly
regarding this (contact@hatch51.com)
A recent review
article details the possibilities of bio-printing and its applications. Read

“Abstract: Biofabrication
of living structures with desired topology and functionality requires the
interdisciplinary effort of practitioners of the physical, life and engineering
sciences. Such efforts are being undertaken in many laboratories around the
world. Numerous approaches are pursued, such as those based on the use of
natural or artificial scaffolds, decellularized cadaveric extracellular
matrices and, most lately, bioprinting. To be successful in this endeavor, it
is crucial to provide in vitro micro-environmental clues for the cells
resembling those in the organism. Therefore, scaffolds, populated with
differentiated cells or stem cells, of increasing complexity and sophistication
are being fabricated. However, no matter how sophisticated scaffolds are, they
can cause problems stemming from their degradation, eliciting immunogenic
reactions and other a priori unforeseen complications. It is also being
realized that ultimately the best approach might be to rely on the
self-assembly and self-organizing properties of cells and tissues and the
innate regenerative capability of the organism itself, not just simply prepare
tissue and organ structures in vitro followed by their implantation. Here we
briefly review the different strategies for the fabrication of
three-dimensional biological structures, in particular bioprinting. We detail a
fully biological, scaffoldless, print-based engineering approach that uses
self-assembling multicellular units as bio-ink particles and employs early
developmental morphogenetic principles, such as cell sorting and tissue fusion.”
