Centre for Innovation scientist recognized for his contributions to the field of cryobiology

Dr. Geraldine Walsh

Centre for Innovation scientist Dr. Jason Acker was recently inducted as a Fellow of the Society for Cryobiology, a prestigious international award that recognizes individuals who have had an exemplary impact on the field of cryobiology. Congratulations to Dr. Acker, who received this award over the summer at the Society for Cryobiology’s annual meeting in San Diego.

What is cryobiology?

The Society for Cryobiology is the international society for low temperature biology and medicine. Cryobiology is the science of life at low temperatures. It includes the study of cells, organs, and tissues exposed to below normal temperatures. Cryobiology has many applications in the fields of transfusion and transplantation medicine. For example, plasma and red blood cells are frozen (cryopreserved) and platelets are stored at hypothermic temperatures so they can be stored for longer. Freeze-drying (lyophilization) is used to preserve plasma and plasma-derived medicines. Organs for transplantation are preserved under cold (hypothermic) conditions. Cryopreservation and lyophilization are not new processes, but they remain imperfect; freezing, thawing, and drying processes can result in cell or tissue damage. This affects that quality of the thawed cells and tissues. Researchers are continually working to better understand and improve cryopreservation processes.

What's Fellowship in the Society for Cryobiology?

Fellowship in the Society for Cryobiology is awarded to individuals who have made an outstanding and sustained impact on the field of cryobiology. Only 27 scientists have been granted this prestigious award, and Dr. Acker is one of only four Canadians to have been inducted as a Fellow in the society’s 55-year history.

Why was Dr. Acker recognized?

Dr. Acker has had a long-standing and enduring interest in the field of cryobiology, in particular cryopreservation, with publications in the area spanning the past two decades. His work has specifically focused on the development of intracellular protectants as a novel class of molecules that can protect cells and tissues during freezing and drying. Ice recrystallization within cells is the cause of much of the damage that occurs with freezing and thawing. Among other advances, Dr. Acker’s research has improved understanding of how these ice crystals form in cells and what can be done to prevent their formation. Dr. Acker and his team have investigated various “cryoprotectant” solutions that can be used to protect cells from the damage associated with cryopreservation.

Recently, together with his colleague Dr. Robert Ben, Dr. Acker has discovered a new way to prevent ice recrystallization in cells. He is currently working to further understand and develop this unique technology. This work may change the way blood products, stem cells and other cells, tissues and organs are stored in the future. Dr. Acker and his group are also interested in investigating the issues associated with cryopreservation and desiccation processes in the large-scale environment of a blood operator.

In addition to his scientific contributions, Dr. Acker has had extensive and long-standing service to the Society for Cryobiology. As a member since 1996, Dr. Acker served as editor of the society’s newsletter, editorial board member, committee chair, annual meeting co-chair, member of its Board of Governors, and most recently, as president. Through his role as president, Dr. Acker initiated a renewal of the society’s bylaws, committees and working groups, helped establish a permanent secretariat with the hiring of an executive director, and helped redevelop how annual meetings are structured and organized. Dr. Acker was recognized with the society’s highest honour because of his distinguished service to the Society, sustained scientific contributions to the field and his training of the next generation of cryobiologists.

What does this award mean to Dr. Acker?

In Dr. Acker’s own words:

”It is an incredible honour to be inducted as a Fellow of the Society for Cryobiology. I have been fortunate enough to have had the opportunity to contribute in a meaningful way to a very 'cool' science that has led to improvements in how we store biological materials for use in transfusion medicine, transplantation, biotechnology, and conservation biology. Through all of this I have had the privilege of working with an outstanding group of research collaborators, technicians, students and industrial partners to realize real impacts from our research. The most exciting thing about working in this area of science is that we are just now starting to see the benefits of more than 20 years of research from our group. The future is very exciting!”
