Dr. Buckmaster studies conditions that affect blood flow, particularly focusing on thrombocytopenia, which is a drop in platelet count that can lead to blood clotting problems. One of his important research areas is how heparin, a common blood thinner used in surgeries, can cause serious complications like heparin-induced thrombocytopenia (HIT). He also investigates the behavior of smooth muscle cells in blood vessels, specifically how growth factors affect cell growth and function, which is relevant to treating vascular injuries.
Key findings
After treating a patient with heparin during heart surgery, Dr. Buckmaster found that rapid identification of HIT is crucial to prevent severe complications, such as significant limb tissue damage.
In his study on aortic smooth muscle cells, Dr. Buckmaster discovered that exposure to basic-FGF (FGF2) caused polyamine levels to significantly increase, influencing the growth processes within these cells.
The research on FGF2 showed that a key enzyme for polyamine production increased within just 6 hours of treatment, demonstrating a rapid response in blood vessel cells post-injury.
Frequently asked questions
Does Dr. Buckmaster study heparin-induced thrombocytopenia?
Yes, he studies how heparin can lead to thrombocytopenia and the complications that arise from it, particularly in patients undergoing heart surgery.
What treatments has Dr. Buckmaster researched?
He has researched treatment complications related to heparin and the effects of growth factors on vascular smooth muscle cells, which are important for blood vessel health.
Is Dr. Buckmaster's work relevant to patients undergoing heart surgery?
Absolutely, his research highlights the risks of complications like thrombocytopenia during heart surgeries, helping doctors and patients better recognize and manage these risks.

Plain English This study looked at a 52-year-old man who developed serious complications in his fingers due to a condition called heparin-induced thrombocytopenia (HIT), which he got after treatment with heparin. The researchers found that he needed surgery to save his limbs because of tissue damage caused by reduced blood flow. This matters because it highlights how vital it is to quickly recognize HIT in patients, especially those undergoing major heart surgeries, to prevent severe complications.
Who this helps: This helps patients undergoing heart surgery and their doctors by raising awareness about the risks of HIT.

Plain English This study looked at how a protein called basic-FGF (FGF2) affects the growth and function of smooth muscle cells in blood vessels after injury. Researchers found that when these cells were exposed to FGF2 for 24 to 48 hours, their levels of polyamines—involved in cell growth—increased significantly. Specifically, the increase in a key enzyme for polyamine production was observed just 6 hours after FGF2 treatment, highlighting the impact of FGF2 on these processes.
Who this helps: This research is important for doctors treating patients with vascular injuries or conditions that involve smooth muscle cell activity.
