As a clinician scientist, Dr. Cui’s research has originally focused on two main aspects: (1) Pathogenesis and treatment of osteonecrosis and (2) Stem cell therapy for osteogenesis. His research team has found that steroids induce adipogenesis by osteoprogenitor cells and stimulate expression of a fat-specific gene while inhibiting osteogenesis by down-regulating osteoblastic gene expression. He has proposed that this may be an important mechanism by which osteonecrosis and osteoporosis develops. The results of this study were published in the Journal of Bone and Joint Surgery, which was selected as an abstract in the Yearbook of Orthopaedics and won the William Harris Award by the Orthopaedic Research Society. Based on these findings, he studied the effects of lipid-clearing agents on steroid-induced adipogenesis by osteoprogenitor cells and discovered that lovastatin, a HMG CoA reductase inhibitor, can counteract the effect of steroids on adipogenesis and thereby maintain the osteogenic properties of the cell. Similar findings in an in vivo study with a steroid-treated chicken model for osteonecrosis supported the in vitro data. His paper entitled “Lovastatin Prevents Steroid-Induced Adipogenesis and Osteonecrosis” was selected for the Otto E. Aufranc Award by the American Hip Society. His other work includes studies on a multipotent bone marrow cell, which has been transduced with a traceable gene as a marker as well as with growth factor genes. The results of the study, “The Pathogenesis and Prevention of Steroid-induced Osteonecrosis” received the Nicholas Andry Award from The American Association of Bone and Joint Surgeons and published in Clinical Orthopaedics and Related Research. His recent research activities in this area are focusing on finding therapeutic agents to prevent adipogenesis and apoptosis of stem cell in response to glucocorticoid treatment which is the major contributing factor for osteonecrosis. The research findings were recently published in one of the top orthopaedic research journals, the Journal of Orthopaedic Research, with a manuscript titled “Fullerol antagonizes dexamethasone-induced oxidative stress and adipogenesis while enhancing osteogenesis in a cloned bone marrow mesenchymal stem cell”. They successfully received a NIH R21 grant to continue support their efforts studying potential therapeutic effects of antioxidants on prevention of osteonecrosis and osteoporosis in a rabbit model.
The delivery of marrow stromal cells with or without transfection using therapeutic genes may provide a valuable treatment for musculoskeletal diseases such as fractures, osteonecrosis, osteoporosis, and some genetic abnormalities. With the support of an OREF Zimmer Career Development Award, Dr. Cui was able to perform a study on transduction of a mouse and human bone marrow stem cell using plasmid and adenovirus containing both VEGF and BMP-6 genes. The two growth factors (VEGF and BMP-6) are both translated from a single mRNA due to the presence of IRES (Internal Ribosome Entry Site) between the two coding sequences. Using this vector, transient transduction of a cloned bone marrow stem cell was achieved with high efficiency. The efficacy of osteogenesis and angiogenesis by transfected cells was improved significantly. Along this line of research, Dr. Cui’s research team has received MTF (Musculoskeletal Transplant Foundation) Career Development Award to support a study entitled “An optimal deliverable composite graft for bone repair”; OREF/MTF Research Grant to support another project: “Stem cell-based angiogenic and osteogenic gene therapy to enhance bone defect repair”; and a grant from Arthritis National Research Foundation to support the study: “New strategies for treatment of osteonecrosis using stem cells and growth factors”.
In collaboration with School of Biomedical Engineering, Dr. Cui’s research team successfully received the Department of Defense (DOD) Idea Development Award to support their study: “Novel Bioactive Coatings to Improve Allograft Incorporation”. The goal of the project was to engineer continuous polymer coatings within the pore network of allograft bone for sustained delivery of bioactive factors that target sphingosine 1-phosphate receptors (S1P). S1P is a pleiotropic autocrine and paracrine signaling phospholipid growth factor that impacts proliferation and migration of endothelial cells, mural cells (i.e. vascular smooth muscle cells and pericytes), and osteoblastic cells through a family of high-affinity G protein-coupled receptors (S1P1-5). They have shown that delivery of S1P receptor agonists from poly(lactic-co-glycolic acid) promotes new bone ingrowth by inducing neovascularization and locally regulating the balance of inflammatory cells and osteoblastic (bone forming) cell recruitment.
As a practicing joint replacement (adult reconstruction) surgeon, Dr. Cui’s clinical research has been focused on outcomes of joint replacement surgery and fracture healing. He hopes to translate cellular and molecular techniques to clinical use so that they can improve treatment outcomes of orthopaedic patients, especially patients with osteoarthritis, osteonecrosis, osteolysis, osteoporosis and non-union fractures.
