Tricky science made simple, Valentine’s edition

When we think of Valentine’s Day, we think of hearts. And when we think of hearts, we think of their life-sustaining role of pumping blood. But where does that blood come from? How does it get made?

A great resource to find answers to those questions and understand the role of stem cells in blood formation is now available. “What is a hematopoietic stem cell?” narrated by Dr. Connie Eaves is the latest video in Stem Cell Shorts series that explains how hematopoietic stem cells (HSCs) produce new blood cells.

Contained in the bone marrow, HSCs can produce new blood cells or regenerate the blood production system. In fact, bone marrow transplants have treated patients with a variety of blood cancers and disorders, including multiple myeloma, leukemia and lymphoma for decades.

Dr. Eaves, a professor in the Department of Medical Genetics at the University of British Columbia, is a leader in the field of hematopoietic stem cell biology. Her work has led to advances in treatment for leukemia. Currently, she is researching the unique properties of normal and cancerous stem cells in a variety of tissues to improve treatments for breast cancer and leukemia.

The new video, produced by Ben Paylor, a PhD candidate at the University of British Columbia, and Dr. Mike Long, a post-doctoral fellow at the University of Toronto, is co-sponsored by the Canadian Stem Cell Foundation and the Stem Cell Network.

All the videos — including “What is a stem cell?” narrated by Dr. Jim Till, “What are embryonic stem cells?” voiced by Dr. Janet Rossant, “What are induced pluripotent stem cells?” narrated by Dr. Mick Bhatia, “What is stem cell tourism?” voiced by Prof. Timothy Caulfield, “What is a cancer stem cell?” narrated by Dr. John Dick, “What is a retinal stem cell?” voiced by Dr. Derek van der Kooy and “What is a hematopoietic stem cell?”  – are now available on the Foundation’s You Tube channel.

The final instalment of the series,“What is a neural stem cell?” narrated by Dr. Sam Weiss, will be released soon. Stay tuned!

‘Cancer is not beyond us’

Today is World Cancer Day. Under the tagline “Not beyond us,” the campaign’s goal is to raise awareness about the leading cause of death in Canada. Cancer is responsible for 30% of all deaths.

This year’s global campaign encourages prevention, early detection, treatment and care. Its message is a simple one: solutions to fight cancer are within our reach.

Stem cells represent a valid treatment option for certain types of blood cancers and solid tumours, and there is hope that more stem cell therapies for cancer will be available in the near future.blood

Canadian scientists are at the forefront of cancer research.  One of the major contributions to the field comes from Dr. John Dick, senior scientist at Princess Margaret Cancer Centre and the McEwen Centre for Regenerative Medicine in Toronto. He was the first to isolate cancer stem cells — in leukemia in 1994 and in colon cancer in 2007. Recently, he and his team found a way to disarm a gene called BMI-1 that regulates colorectal cancer stem cells.

But there is potential to do more. The Canadian Stem Cell Strategy & Action Plan, could lead to novel treatments for cancer. In fact, the goal of the Strategy is for Canada to lead the way in delivering five to 10 safe and effective treatments for chronic diseases within 10 years.

By making stem cell research a national priority Canada has the potential to show that cancer is “not beyond us.”
