Using their novel Freeform Reversible Embedding of Suspended Hydrogels (FRESH) 3D bioprinting technique, which allows for the printing of soft living cells and tissues, Carnegie Mellon's Feinberg lab ...

There are many variables affecting the quality of frozen sections. You may have to experiment with different methods. Be advised that it can be difficult to get acceptable sections from some tissues.

The existing 3D-printed scaffolds commonly possess a thick feature size of hundreds of micrometers, which is too large for most cells (10–20 μm) to attach and proliferate for promoting tissue ...

This flexibility enables the fabrication of composite structures that best replicate the physiological conditions that surround the tissue, such as mechanical properties and topographical cues. 10 Due ...
