New to tissue engineering and/or neural stem cells? This review & textbook are for you!

Author: Guest, 09/20/17

Samantha is a PhD Candidate studying neural stem cell biology in Dr. Derek van der Kooy’s lab at the University of Toronto. Her research focuses on neural stem cell hierarchies in the developing mammalian brain, and activation of quiescent stem cells in the adult brain. She is also an avid science communicator on social media…Read more

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

Improving our understanding of how aging happens

Author: Stacey Johnson, 08/03/17

Dr. William Stanford, The Ottawa Hospital, is working with colleagues to help patients with Hutchinson-Gilford progeria syndrome (HGPS). They have shown that cells from individuals with HGPS – also called progeria – can be genetically reprogrammed, turning them into stem cells that don’t show any signs of aging. According to the news release issued by…Read more

Right Turn: Science is art and art inspires science

Author: Stacey Johnson, 07/28/17

“Anyone who views something under a microscope or through a telescope will tell you that science is art, and that art is the perfect way to convey science.” (Amanda Kwieraga) If you wander through the office where I work, you will come to the same conclusion. The submissions we have received from several years of…Read more

Relay race to finish off inflammatory cells

Author: Holly Wobma, 07/12/17

I don’t have many distinct memories from childhood. Certainly not of global events. But given the sweltering weather, the recent Canada 150 celebration, and a cool new paper published in Cell Chemical Biology, my mind wandered back to the ’96 summer Olympics (Atlanta), when Donovan Bailey raced through the finish line with his arms in…Read more

Immune to cancer, long-lived and really ugly

Author: Jovana Drinjakovic, 06/27/17

They could well be the ugliest animals on the planet, but naked mole rats don’t get cancer or suffer decrepitude from old age. No wonder scientists are working hard to unlock the secrets of these bizarre-looking creatures that could teach us how to stave off disease and repair brains. With large protruding teeth, squinting useless…Read more

What time zone is your heart tissue In?

Author: Holly Wobma, 06/19/17

Our lives our governed by our concept of time. Whether you are relatively spontaneous or a micromanager of your daily schedule, how we coordinate our work and interactions with other people comes down to the 24-hour clock we picture in our minds. Of course, this 24-hour clock is more than just a social construct. It…Read more

Location, location, location – stem cells need the right neighbours

Author: David Kent, 06/12/17

Last month two papers created a pretty big wave in the blood stem cell field: Work from Harvard Medical School and Cornell University showed that functional human blood stem cells could be created from reprogrammed cells. While it is most certainly the closest that researchers have come to creating blood stem cells in large numbers…Read more

The “immunity saboteurs ” – otherwise known as T-cells

Author: Hamideh Emrani, 06/07/17

Did you know that a healthy person with a healthy lifestyle and diet might still end up being diabetic? That is certainly the case with those who have type 1 diabetes (T1D). In T1D, the patient’s body has lost the ability to produce insulin. Insulin is a hormone that acts like an agent and takes…Read more

Right Turn: Eventual relief for those suffering from Crohn’s?

Author: Stacey Johnson, 05/26/17

Recently, a friend posted on Facebook the news about her teenage son who, a year ago, had been suffering from an undiagnosed condition. Her son’s doctor didn’t treat the symptoms very seriously until the mother insisted something was wrong and implored him to identify the cause. Finally, her son was diagnosed with Crohn’s disease. Along…Read more
