The making of a bioactive “tissue paper”

Author: Hamideh Emrani, 09/06/17

If you live in Toronto (Canada), you know that we have two seasons: winter and construction season. Between new condo developments and homes being renovated or restored, construction is everywhere. Right now, there are five active projects going on in the relatively small neighborhood where I live! I’m annoyed by the traffic delays and noise…Read more

Right Turn: Health care solutions on demand through 3D printing

Author: Stacey Johnson, 04/21/17

3D printing is a topic we’ve covered before at Signals. It’s still hot and trendy, and still making the cut on top technology lists. Back in 2012, Chris Anderson, the former editor-in-chief of Wired, predicted that 3D printing “will be bigger than the web.” Given that good 3D printers are now cheap enough (US$150) to…Read more

Biomaterials and the “ouch” factor in Olympics and sports

Author: Hamideh Emrani, 09/07/16

Other than multiple heat waves, this summer has been all about sports and the excitement of different tournaments. The Europe 2016 soccer league, the 2016 Olympics in Brazil and last but not least on my list is my sons’ soccer endeavors. I am a fan of soccer and as the mother of two young soccer…Read more

Highlights from the World Biomaterials Congress Part II: Stepping up delivery strategies

Author: Samantha Payne, 06/20/16

This post is the second of two covering the World Biomaterials Congress. To read my previous blog about the use of biomaterials to study cell behaviour and differentiation in vitro, please click here. This post will cover the use of biomaterials for in vivo delivery strategies. Cartilage, despite its essential role in the movement of…Read more

A double duty scaffold for cell delivery to the brain

Author: Samantha Payne, 04/07/16

Neurodegenerative diseases of the brain, such as Parkinson’s and Alzheimer’s, are a leading cause of disability in Canada, but despite the significant burden on patients, caregivers and the health-care system, we still lack a cure. An active area of research for these diseases is focused on the transplantation of exogenous cells to replace degenerated neurons…Read more

Right Turn: Bio-hybrid device mimics kidney to remove need for dialysis

Author: Stacey Johnson, 03/04/16

Last week, I wrote about Dr. Leon Bellan’s creative solution to engineering artificial blood vessels for lab-grown organs: cotton candy! As much as I was impressed with his out-of-the-box thinking, I also really liked the excellent video produced by Vanderbilt University (VU), where Dr. Bellan runs his lab. So I went hunting for other VU…Read more

Regenerating a broken heart

Author: Guest, 02/11/16

Samantha is a PhD student in the Chemical Engineering and Applied Chemistry department at the University of Toronto. She has previously investigated regeneration in a non-mammalian gecko model during an MSc program, and now currently combines stem cell biology and biomaterials to encapsulate and deliver therapeutic cells to the stroke-injured brain. Samantha became interested in…Read more

An interview with bioengineering pioneer Kevin Healy

Author: Hamideh Emrani, 01/05/16

In the fourth in her series on “What drives research in the field of biomaterials?” blogger Hamideh Emrani interviews Professor Kevin E. Healy at the University of California, Berkeley. You can catch up on Hamideh’s earlier interviews here. I met Professor Kevin Healy at the University of California, Berkeley. He is the Jan Fandrianto Distinguished…Read more

A paper on stem cells… on paper

Author: Holly Wobma, 11/10/15

  The last two decades have seen a number of fascinating innovations in biomaterial scaffolds development. This comes from the growing realization that 2D culture of cells can only do so much in terms of mimicking physiological niches of the body. To encourage stem cells towards a particular mature cell fate, or to mimic disease…Read more

Right Turn: Bone grafts, made-to-order

Author: Peter Raaymakers, 12/26/14

In a TED video from earlier in the year, Nina Tandon and Sarindr Ick Bhumiratana of EpiBone talked about their incredible technique to use biomaterials and stem cells to generate customized bone material for implant. In Tandon’s words, “If you need a piece of human bone, you can use your own cells to grow your own.” EpiBone’s…Read more
