研究室紹介
Professor Sang Woo Park's research lab specializes in plastic and reconstructive surgery, with a strong focus on microsurgical techniques and tissue engineering. The lab investigates innovative methods to enhance flap survival and tissue regeneration, particularly in challenging clinical scenarios such as diabetic foot ulcers and complex craniofacial reconstruction. Key research directions include angiogenesis modulation using pharmacological agents like deferoxamine, the development of advanced graft materials for aesthetic and functional reconstruction, and the application of biological and metabolic engineering to improve outcomes in soft tissue repair. The lab also explores molecular mechanisms underlying scar formation and the role of growth factors in wound healing and tissue regeneration.

METHODS: Cell viability, tube formation, and mRNA expression were measured in human umbilical vein endothelial cells treated with deferoxamine. A total of 36 rats were then used for an in vivo study. A dose of 100 mg/kg of deferoxamine was injected subcutaneously into the rat scalp every other day for five treatments.
BACKGROUND: In Asian rhinoplasty, most patients need correction of the nasal tip and columella along with dorsal augmentation. A complete septal extension graft can effectively and concomitantly correct less projected tips, retracted columellar bases, and acute columella-labial angles. However, the amount of septal cartilage is not sufficient as a source for the graft; therefore, the authors used porous high-density polyethylene sheets as their graft material. METHODS: Fifty-eight patients were
BACKGROUND: Hypertrophic scars and keloids are associated with abnormal levels of growth factors. Silicone gel sheets are effective in treating and preventing hypertrophic scars and keloids. There has been no report on the change in growth factors in the scar tissue following the use of silicone gel sheeting for scar prevention. A prospective controlled trial was performed to evaluate whether growth factors are altered by the application of a silicone gel sheet on a fresh surgical scar. METHODS:
BACKGROUND: Free flap surgery for head and neck defects has gained popularity as an advanced microvascular surgical technique. The aims of this study are first, to determine whether the known risk factors such as comorbidity, tobacco use, obesity, and radiation increase the complications of a free flap transfer, and second, to identify the incidence of complications in a radial forearm free flap and an anterolateral thigh perforator flap. METHODS: We reviewed the medical records of patients with
The metabolic engineering of epothilones, as secondary metabolites, was investigated using Sorangium cellulosum to achieve the selective production of epothilone B, a potent anticancer agent. Thus, the propionyl-CoA synthetase gene (prpE) from Ralstonia solanacearum was heterologously expressed in S. cellulosum to increase the production of epothilone B. Propionyl-CoA synthetase converts propionate into propionyl-CoA, a potent precursor of epothilone B. The recombinant S. cellulosum containing t
In diabetic foot patients, wound coverage options are quite limited due to vascular abnormalities. However, even though significant atherosclerotic changes are found in major vessels of the lower leg in diabetic foot patients, perforating vessels, which are used as the vascular pedicle of propeller perforator flaps, are often spared from atherosclerosis. Therefore, the propeller perforator flap could be an alternative option for diabetic foot patients. The purpose of this study was to compare th
