background: adipose-derived stem cells (adsc) could be an appealing alternative to bone marrow stem cells (bmsc) for engineering cell-based osteoinductive grafts. meanwhile, prior studies have demonstrated that melatonin can stimulate osteogenic differentiation. therefore, we assayed and compared the melatonin effect on osteogenic differentiation of bmsc with that of adsc. methods: mesenchymal ...

The controversial metaplastic potential of the meninges1 has led to a number of varying accounts in medical literature about the relationship of neoplastic adipose tissue to the covering membranes of the central nervous system. Reports of a supposedly congenital lipoma in the left cerebral hemisphere, of an extradural lipoma that compressed the lumbar spinal cord, and of a similar sacral tumor ...

introduction hemangiopericytomas (hpcs) are rare neoplasms which account for approximately 1% of primary vascular tumors. case presentation we report a 73 years old woman with vague abdominal pain who did not have further significant symptoms and was diagnosed to have retroperitoneal hemangiopericytoma. discussion the tumor was initially diagnosed by ultrasound evaluation. mri showed a lobulate...

introduction: desmoid tumors are very rare, benign fibrous neoplasms arise from the musculoaponeurotic structures throughout the body.   case report: the patient was a   seven-year old boy with a large mandibular mass growing over a period of six months. his ct-scan showed a large mass, 13 cm in diameter in the cheek area extending to the neck and trachea. biopsy was compatible with desmoid fib...

tendon never restores the complete biological and mechanical properties after healing. bone marrow and recently adipose tissue have been used as the sources of mesenchymal stem cells, which have been proven to enhance tendon healing. stromal vascular fraction (svf), derived from adipose tissue by an enzymatic digestion, represents an alternative source of multipotent cells, which undergo differ...

Unaltered fat is a permanent component of the abdominal cavity, even in slim individuals. Visceral adiposity is one of the important factors contributing to diabetes, cardiovascular diseases and certain neoplasms. Moreover, the adipose tissue is an important endocrine and immune organ of complex function both when normal and pathological. Its role in plastic surgery, reconstruction and transpla...

Generally benign, renal angiomyolipomas are neoplasms composed of mature adipose tissue, smooth muscle, and thick-walled blood vessels. Although asymptomatic, massive retroperitoneal hemorrhage from angiomyolipomas accompanied by hypovolemic shock has been found in up to 10% of patients, usually those with large tumors. We report the case of a 33-year-old woman with spontaneous rupture of an an...
