currently autografts are gold standards for craniomaxillofacial bone regeneration. but autografts have some limitations. bone tissue engineering has been introduced to overcome these limitations. it consist three components: stem cells, growth factor, and scaffold. scaffold provides an environment for bone growth and simplifies cell adhesion, differentiation and proliferation. in this review, a...

Enhancing muscle growth while reducing fat accumulation improves the efficiency of animal production. The fetal stage is crucial for skeletal muscle development. Fetal muscle development involves myogenesis, adipogenesis, and fibrogenesis from mesenchymal multipotent cells (MC), which are negatively affected by maternal nutrient deficiencies. Enhancing myogenesis increases the lean-to-fat ratio...

Bone marrow mesenchymal stem cells (BMSCs) are considered as multipotent cells, representing a multi-lineage potential to differentiate into mesodermal lineages of mesenchymal tissues, including cartilage, bone, fat, muscle and tendon. Tissue engineering in BMSCs has made great advances in the regeneration of cartilage and bone defects. To uncover the mechanisms of the multipotent differentiati...

N-3 polyunsaturated fatty acids (PUFA) have anti-inflammatory effects and were considered useful for the treatment of rheumatoid arthritis (RA). Recently, several studies suggested that n-3 PUFAs attenuated arthritis in animal model and human, however the mechanism is still unclear. Interleukin 17 (IL-17) is a pro-inflammatory cytokine mainly produced by T helper 17 (Th17) cells which cause tis...

BACKGROUND Mutations in the EXT genes disrupt polymerisation of heparan sulphates (HS) and lead to the development of osteochondroma, an isolated/sporadic- or a multifocal/hereditary cartilaginous bone tumour. Zebrafish (Danio rerio) is a very powerful animal model which has shown to present the same cartilage phenotype that is commonly seen in mice model and patients with the rare hereditary s...

purpose to date, little is known about the effects of a reduced level of jumping exercise regimens on bone turnover markers and mass. this study investigates the effects of different jumping exercise regimens with varying exercise loads on serum bone turnover markers and bone mass in female rats. methods a total of 144 female rats aged 12 weeks, were divided into 12 groups as follows: no exerci...

In this prospective study the effect of low dose methylprednisolone succinate (10mg/kg) on the incidence of fat embolism syndrome and isolated arterial hypoxemia in 99 patients with long bone fracture (52 control and 47 steroid-trated subjects) was studied. Frequency of fractures among the selected patients was as follows: femoral fracture 52.5%, tibial fracture 36.4%, both femoral and tibial f...

The presence of adipose tissue in the thyroid gland is a rare finding. Thyrolipoma or adenolipoma of the thyroid is a benign, encapsulated lesion of the thyroid composed of variable amounts of fat and glandular elements. This report presents a case of thyrolipoma in a 69-yr-old female presenting with neck swelling and respiratory distress. Differential diagnosis of the fat-containing thyroid le...

Fat infiltration within the bone marrow is easily observed in some postmenopausal women. Those fats are mainly derived from bone marrow mesenchymal stem cells (BMMSCs). The increment of adipocytes derived from BMMSCs leads to decreased osteoblasts derived from BMMSCs, so the bidirectional differentiation of BMMSCs significantly contributes to osteoporosis. Icariin is the main extractive of Herb...
