3D bioprinting of BM-MSCs-loaded ECM biomimetic hydrogels for in vitro neocartilage formation

M Costantini, J Idaszek, K Szöke, J Jaroszewicz… - Biofabrication, 2016

Abstract In this work we demonstrate how to print 3D biomimetic hydrogel scaffolds for
cartilage tissue engineering with high cell density (> 10 7 cells ml− 1), high cell viability (85÷
90%) and high printing resolution (≈ 100 μm) through a two coaxial-needles system. The ...

Yield stress determines bioprintability of hydrogels based on gelatin-methacryloyl and gellan gum for cartilage bioprinting

VHM Mouser, FPW Melchels, J Visser, WJA Dhert… - Biofabrication, 2016

Abstract Bioprinting of chondrocyte-laden hydrogels facilitates the fabrication of constructs
with controlled organization and shape eg for articular cartilage implants. Gelatin-
methacryloyl (gelMA) supplemented with gellan gum is a promising bio-ink. However, the ...

[HTML] Engineering zonal cartilage through bioprinting collagen type II hydrogel constructs with biomimetic chondrocyte density gradient

X Ren, F Wang, C Chen, X Gong, L Yin, L Yang - BMC Musculoskeletal Disorders, 2016

Background Cartilage tissue engineering is a promising approach for repairing and
regenerating cartilage tissue. To date, attempts have been made to construct zonal cartilage
that mimics the cartilaginous matrix in different zones. However, little attention has been ...

[HTML] Research on the printability of hydrogels in 3D bioprinting

Y He, FF Yang, HM Zhao, Q Gao, B Xia, JZ Fu - Scientific Reports, 2016

Abstract As the biocompatible materials, hydrogels have been widely used in three-
dimensional (3D) bioprinting/organ printing to load cell for tissue engineering. It is important
to precisely control hydrogels deposition during printing the mimic organ structures. ...

[HTML] A bioink by any other name: terms, concepts and constructions related to 3D bioprinting

WG Whitford, JB Hoying - 2016

Recently, specialized applications of 3D printing have extended into the biological realm. As
the field is so new, related activities are being approached from groups with disparate specialties
and backgrounds. Therefore, few firm, unambiguous and universally understood ...

[PDF] 3D Bioprinting for Cartilage

L Margolis

Abstract—Even though artificial cartilage is one of the hardest tissues to recreate, it is also
one of the first tissues to be successful engineered. From creating scaffolds for artificial
cartilage to building the cartilage by laser bioprinting or inkjet bioprinting, it has now been ...
