Although it has been reported that mesenchymal stem cells (MSCs) suppress tumor growth in vitro and in vivo, little is known about the underlying molecular mechanisms. We found that type I interferon is expressed in adipose tissue-derived stem cells (ASCs) cultured at high density, and ASCs and their conditioned medium (ASC-CM) suppress the growth of MCF-7(More)
PURPOSE Mesenchymal stem cells (MSCs) are multipotent and give rise to distinctly differentiated cells from all three germ layers. Neuronal differentiation of MSC has great potential for cellular therapy. We examined whether the cluster of mechanically made, not neurosphere, could be differentiated into neuron-like cells by growth factors, such as epidermal(More)
This study created a new staging system using a risk model that employed clinical factors that were associated with recurrence, verified by preoperative clinical information and intraoperative finding and was compared with other staging systems. A review was conducted of patients who have undergone thyroidectomy and followed-up between January 1, 1983 and(More)
PURPOSE The main issue with the current ultrasonography (US) guidelines is the overestimation of malignant and indeterminate nodules as they do not aid in making decisions to treat patients. To overcome this, new US guidelines for thyroid nodules that have been shown to be better correlated with cytologic results have been proposed. We also suggested(More)
BACKGROUND This study assessed the results of robotic thyroidectomy by fellowship-trained surgeons in their initial independent practice, and whether standard fellowship training for robotic surgery shortens the learning curve. METHODS This prospective cohort study evaluated outcomes in 125 patients who underwent robotic thyroidectomy using gasless(More)
We present the first report of ovarian dysgerminoma in Cowden syndrome, presenting in a 7-year-old girl. In her second decade, a hamartomatous soft tissue extremity mass and diffuse gastrointestinal hamartomatous polyposis with pathologic features suggestive of either juvenile, Peutz-Jeghers, or Cowden polyps were identified, along with diffuse esophageal(More)
PURPOSE Current management for patients with differentiated thyroid cancer includes near total thyroidectomy and radioactive iodine therapy followed by administration of supraphysiological doses of levothyroxine (L-T4). Although hyperthyroidism is a well known risk factor for osteoporosis, the effects of L-T4 treatment on bone mineral density (BMD) in(More)
Mesenchymal stem cells (MSCs) secrete neurotrophic factors, and have been reported to improve functional outcomes in animal models of neurodegenerative diseases such as cerebral ischemia, stroke, spinal cord lesions, and Parkinson’s disease. Previously, we found that adipose tissue-derived mesenchymal stem cells (ASCs) cultured at high cell density(More)
