Journal ArticleDOI
Bio-ink properties and printability for extrusion printing living cells
Johnson H.Y. Chung,Sina Naficy,Zhilian Yue,Robert M. I. Kapsa,Robert M. I. Kapsa,Anita F. Quigley,Anita F. Quigley,Simon E. Moulton,Gordon G. Wallace +8 more
TL;DR: Alginate (Alg) was selected as the major component of the 'bio-ink' formulations for extrusion printing of cells and the viability of primary myoblasts delivered as a myoblast/Alg-Gel bio-ink was not affected by the printing process, indicating that the Alg-gel matrix provides a potential means to print 3D constructs that may find application in myoregenerative applications.
Journal ArticleDOI
Development of the Biopen: a handheld device for surgical printing of adipose stem cells at a chondral wound site.
Cathal D O'Connell,Claudia Di Bella,Claudia Di Bella,Fletcher William Thompson,Cheryl Augustine,Stephen Beirne,Rhys Cornock,Christopher J Richards,Johnson H.Y. Chung,Sanjeev Gambhir,Zhilian Yue,Justin L Bourke,Justin L Bourke,Binbin Zhang,Adam Taylor,Anita F. Quigley,Anita F. Quigley,Anita F. Quigley,Robert M. I. Kapsa,Robert M. I. Kapsa,Robert M. I. Kapsa,Peter F. M. Choong,Peter F. M. Choong,Gordon G. Wallace +23 more
TL;DR: The development of a handheld biofabrication tool, dubbed the 'biopen', which enables the deposition of living cells and biomaterials in a manual, direct-write fashion and paves the way for the use of 3D bioprinting during the surgical process.
Journal ArticleDOI
Processable conducting graphene/chitosan hydrogels for tissue engineering
Sepidar Sayyar,Eoin Murray,Eoin Murray,Brianna C. Thompson,Brianna C. Thompson,Johnson H.Y. Chung,David L. Officer,Sanjeev Gambhir,Geoffrey M. Spinks,Gordon G. Wallace +9 more
TL;DR: These chitosan-graphene composites show great promise for use as conducting substrates for the growth of electro-responsive cells in tissue engineering.
Journal ArticleDOI
Chondrogenesis of infrapatellar fat pad derived adipose stem cells in 3D printed chitosan scaffold.
Ken Ye,Raed Felimban,Kathy Traianedes,Simon E. Moulton,Gordon G. Wallace,Johnson H.Y. Chung,Anita F. Quigley,Peter F. M. Choong,Damian E. Myers +8 more
TL;DR: Infrapatellar fat pad adipose stem cells can successfully undergo chondrogenesis using TGFβ3 and BMP6 and the cartilage-like tissue that forms on the surface of 3D-printed chitosan scaffold may prove useful as an osteochondral graft.
Journal ArticleDOI
Poly(3,4-ethylenedioxythiophene):dextran sulfate (PEDOT:DS) - a highly processable conductive organic biopolymer.
David G. Harman,Robert Gorkin,Leo Stevens,Brianna C. Thompson,Klaudia Wagner,Bo Weng,Johnson H.Y. Chung,Marc in het Panhuis,Gordon G. Wallace +8 more
TL;DR: Results suggest PEDOT:DS has exceptional potential as an electromaterial for the biointerface and the cytotoxicity of PEDot:PSS is assessed.
