New method can help labs around the world grow stem cells more efficiently

Dr. Richard Carpenedo“Making mature adult cells from stem cells is a long and expensive process. We hope our method can make this more efficient, and ultimately decrease the cost of human therapies.” – Dr. Richard Carpenedo, research associate at The Ottawa Hospital.Researchers from Dr. William Stanford’s lab have developed a more efficient way to grow all kinds of cells from induced pluripotent stem cells (iPSCs). 

IPSCs are human adult skin or blood cells reprogrammed to an embryonic-like state. With the right chemical triggers, they can become any cell in the body. However, making cells from human iPSCs can take up to 50 days. 

The team created a method that made the very first step of this process more efficient, potentially reducing the cost and number of cells needed. Most iPSC methods can only be used to make certain kinds of cells, but this generic method can be adapted to make many cell types. 

The protocol has already been used in Dr. Michael Rudnicki and Dr. Duncan Stewart’s labs to make muscle and vascular cells from iPSCs. The method only took these labs a short time to implement, so the team is confident it can easily be adopted by labs around the world.

 “Making mature adult cells from stem cells is a long and expensive process. We hope our method can make this more efficient, and ultimately decrease the cost of human therapies.” said Dr. Richard Carpenedo, research associate at The Ottawa Hospital.

The Ottawa Hospital: Inspired by research. Driven by compassion 

The Ottawa Hospital is one of Canada’s largest learning and research hospitals with over 1,100 beds, approximately 12,000 staff and an annual budget of over $1.2 billion. Our focus on research and learning helps us develop new and innovative ways to treat patients and improve care. As a multi-campus hospital, affiliated with the University of Ottawa, we deliver specialized care to the Eastern Ontario region, but our techniques and research discoveries are adopted around the world. We engage the community at all levels to support our vision for better patient care. See www.ohri.ca for more information about research at The Ottawa Hospital.

University of Ottawa: —A crossroads of cultures and ideas

The University of Ottawa is home to over 50,000 students, faculty and staff, who live, work and study in both French and English. Our campus is a crossroads of cultures and ideas, where bold minds come together to inspire game-changing ideas. We are one of Canada’s top 10 research universities—our professors and researchers explore new approaches to today’s challenges. One of a handful of Canadian universities ranked among the top 200 in the world, we attract exceptional thinkers and welcome diverse perspectives from across the globe. www.uottawa.ca
