Grayson Storm Cat Award to study stem cell therapy

Catherine Hackett, DVM, Ph.D., has been selected as the winner of the 2010 Storm Cat Career Development Award. The $15,000 award is presented to an early-stage scientist with an interest in a career in equine research.

Selected from numerous competitors, Hackett’s research will focus on equine stem cells in a project entitled “Temporal Analysis of Mesechymal Progenator Cells.” The research will be overseen by Dr. Lisa Fortier, a distinguished researcher, recipient of multiple Grayson-Jockey Club Research Foundation grants, and frequent recipient of Zweig funding.

“My project investigates characteristic cell surface traits of cell populations in bone marrow, particularly the cells that can form tissues such as cartilage, bone, and muscle,” said Hackett. “I look at the surface of different cell types to determine what type of mature cells they will become, such as blood or bone cells. I also study how these surface properties change over time in culture as the cells grow and respond to culture conditions.”

For patients waiting for stem cell therapy, it can take time (e.g. four to eight weeks) for cultured stem cells to divide enough times to reach clinically useful numbers. Hackett hopes to find ways to both decrease the time needed in culture before cells are ready to be implanted and to improve the ability of cells to form the correct tissue

“Stem cells from bone marrow have been used in horses to help heal injuries to tendons, cartilage, and joints, improving repair and changing the patient’s immune response to transplantation of cells or tissues from a different donor,” said Hackett. “The same applications are being investigated in humans to treat similar types of injuries as those seen in the horse. The properties of mesenchymal stem cells are still poorly understood, and we hope our research into their characteristics and behavior can help find ways to improve their clinical utility and function.”

The award is named for the Thoroughbred stallion Storm Cat, which stood at Overbrook Farm in Kentucky. Overbrook is owned by the family of Lucy Young Hamilton, a Foundation board of directors member who personally underwrites the Career Development Award.
