Polymeric biomaterials for cancer nanotechnology themed issue now online

We are delighted to announce that the Polymeric biomaterials for cancer nanotechnology themed issue is now available online.

Polymeric biomaterials for cancer nanotechnology

Guest Edited by Jianjun Cheng (University of Illinois at Urbana-Champaign, USA) and Suzie H. Pun (University of Washington, USA), this themed issue highlights the latest discoveries and innovations in polymeric biomaterials for cancer nanotechnology.

Polymeric biomaterials have been extensively used in nanomedicine formulations for cancer therapy. Preclinical and clinical studies have in general revealed that polymeric nanocarriers, when used for chemotherapeutic drug delivery, reduce systemic toxicity and thus mitigate adverse side effects of the drug. This themed issue contains reviews and research articles in the areas of: (i) expanding the available suite of polymeric biomaterials that can be reproducibly and controllably manufactured at a suitable scale, (ii) designing carriers with improved biodistribution to tumour sites, (iii) increasing tumour distribution and penetration of polymeric nanocarriers, and (iv) controlling efficient drug release at a desired location and with optimal kinetics.

Themed collection for Michael Sefton’s 65th birthday

Nicholas Peppas (University of Texas) introduces our latest themed collection, put together in celebration of Michael Sefton’s 65th birthday.

I am delighted to express my thoughts on the occasion of this special collection in honor of Michael V. Sefton of the University of Toronto. Michael has been a friend for 44 years and has been a source of inspiration for several generations of biomaterials scientists, biomedical engineers, chemical engineers and polymer scientists.  He has been a leader in the fields of biomaterials, regenerative medicine and tissue engineering for the past 40 years.  Michael is recognized for seminal contributions to biomaterials science, regenerative medicine and tissue engineering, for development of novel methods for diabetes treatment and for visionary international leadership of the field of biomedical engineering.

Michael Sefton was born 65 years ago, on October 20, 1949, in London, United Kingdom. At a young age, the family left the UK and came to Canada where Michael, his brother and sister grew up in a loving family, always excelling. He entered the Chemical Engineering Department of the University of Toronto in 1967 and had the fortune to be educated by leading scientists in polymer science and artificial organs. This combination of the two areas led to his decision to pursue a graduate degree in chemical engineering, concentrating on biomaterials. So, we both arrived to the Massachusetts Institute of Technology (MIT) in August 1971 and we started working in the Chemical Engineering Department, he as a research assistant of Ken Smith, I as a volunteer in Ed Merrill’s laboratory. As all loyal students working on biomaterials those days did, we took courses such as 10.68 “Physical Chemistry of Polymers”, 10.64 “Structure and Properties of Polymers” and 10.69 “Polymerization Reactions”, along with 2.905 “Biomaterials” and the famous 10.56 “Chemical Engineering in Medicine”, the legendary course introduced to the curriculum 50 years ago by Ed Merrill and taught by his former PhD student (and our academic brother), the young Clark Colton.

Stem cell-materials interactions themed issue now online

Graphical abstract: Front coverWe hope you enjoy reading our latest themed issue on stem cell—materials interactions, Guest Edited by Matthias Lutolf (EPFL) and Jason Burdick (University of Pennsylvania).

Stem cells have an enormous potential in regenerative medicine and drug discovery but the development of stem cell based therapies and models in these fields has been slow. This is largely due to the difficulty of maintaining functional stem cells in a culture dish or controlling their directed differentiation. Naturally, stem cells reside in highly complex microenvironments (termed ‘niches’) that regulate their behavior.

This themed issue focuses on emerging efforts to engineer these niches to better control and probe stem cell fate in culture and in vivo, including the development of new biomaterials, the better understanding of stem cell and biomaterial interfaces, and the implementation of biomaterials and bioreactors together.

Take a look at these themed issue highlights:

Nanotopography – potential relevance in the stem cell niche Lesley-Anne Turner and Matthew J. Dalby

Biophysical regulation of hematopoietic stem cells C. Lee-Thedieck and J. P. Spatz

Stem cell culture using cell-derived substrates Binata Joddar, Takashi Hoshiba, Guoping Chen and Yoshihiro Ito

Chemically diverse polymer microarrays and high throughput surface characterisation: a method for discovery of materials for stem cell culture A. D. Celiz, J. G. W. Smith, A. K. Patel, R. Langer, D. G. Anderson, D. A. Barrett, L. E. Young, M. C. Davies, C. Denning and M. R. Alexander

Dual-stage growth factor release within 3D protein-engineered hydrogel niches promotes adipogenesis Midori Greenwood-Goodwin, Eric S. Teasley and Sarah C. Heilshorn

Artificial microniches for probing mesenchymal stem cell fate in 3DYujie Ma, Martin P. Neubauer, Julian Thiele, Andreas Fery and W. T. S. Huck
