Background: Recently, tissue engineering has developed approaches for repair and restoration of damaged skeletal system based on different scaffolds and cells. This study evaluated the ability of differentiated osteoblasts from adipose-derived stem cells (ADSCs) seeded into hydroxyapatite/tricalcium phosphate (HA-TCP) to repair bone.

Methods: In this study, ADSCs of 6 canines were seeded in HA-TCP and differentiated into osteoblasts in osteogenic medium in vitro and bone markers evaluated by reverse transcription polymerase chain reaction (RT-PCR).

Objectives: Adipose derived stem cells (ADSCs) can be engineered to express bone specific markers. The aim of this study is to evaluate repairing tibia in animal model with differentiated osteoblasts from autologous ADSCs in alginate scaffold.

Materials And Methods: In this study, 6 canine's ADSCs were encapsulated in alginate and differentiated into osteoblasts.

Paragangliomas are tumors that originate from extra-adrenal medullary neural crest derivatives. They are rarely located in retroperitoneal space. These tumors are often discovered incidentally during imaging studies performed for other reasons.

Objective(s): Osteoarthritis is one of the most common diseases in middle-aged population in the world. Cartilage tissue engineering (TE) has been presented as an effort to introduce the best combination of cells, biomaterial scaffolds and stimulating growth factors to produce a cartilage tissue similar to the natural articular cartilage. In this study, the chondrogenic potential of adipose derived stem cells (ADSCs) was compared with natural articular chondrocytes cultured in alginate scaffold.

Background: Characteristics of differentiated osteoblasts from adipose derived stem cells (ADSCs) in compared with isolated osteoblasts from normal bone such as calvaria are unknown. The aim of this study was determination and comparison of phenotypic characterization between differentiated osteoblasts from stem cells and calvaria osteoblasts in vitro.

Methods: In this study, mesenchymal stem cells were isolated from adipose tissue of human by enzymatic digestion and were differentiated into osteoblasts using osteogenic medium.

Background: Stenosis of trachea with mucosal and cartilage lesions is a challenging problem in tracheal surgery. Owing to ease of harvest and abundance, adipose-derived stem cells (ADSCs) are attractive and increasingly used in tissue engineering. The aim of this study was to evaluate the repair of trachea with autologous stem cells and differentiated chondrocytes from adipose-derived stem cells in an animal model.

Background: The efficacy of subpleural analgesia to reduce postoperative pain intensity in patients after lateral thoracotomy is controversial. In this study, we demonstrated the efficacy of two types of subpleural analgesia.

Methods: This prospective, controlled, randomized, double-blind trial was performed in Department of Thoracic Surgery of Alzahra Hospital associated with Isfahan University of Medical Sciences from June 2009 until August 2010.

For many years different treatments have been used for achalasia. However, esophagomyotomy (ESM) and pneumatic balloon dilation (PBD) have been considered the treatments of choice. Despite new research, some controversies still exist.
