background: despite major progress in our general knowledge related to the application of adult stem cells, finding alternative sources for bone marrow mesenchymal stem cells (mscs) has remained to be challenged. in this study successful isolation, multilineage differentiation, and proliferation potentials of sheep mscs derived from bone marrow, adipose tissue, and liver were widely investigate...

The fibromatosis are a group of lesions that can infiltrate widely, replacing muscle, fat and bone with fibrous tissue of varying cellularity. They do not develop distant metastases, however, locally they show an aggressive and infiltrative behaviour. The major challenge in the diagnosis lies in not over or under diagnose of fibrosarcoma and an underdiagnosis of reactive fibrosis. But this hist...

Objective(s): The present study was aimed to evaluate the time-mannered and dose-dependent effects of 5α-dihydrotestosterone (5α-DHT) on the proliferation and differentiation of bone forming cells using MC3T3-E1 cells. Materials and Methods: Cell proliferation was analyzed using MTS and phase contrast microscopic assays. Osteogenic differentiation was assessed through a series of in vitro exper...

BACKGROUND Choice of appropriate MR pulse sequence is important for any research studies using imaging-derived data. The aim of this study was to compare semiquantitative assessment of subchondral bone marrow edema-like lesions and subchondral cysts using intermediate-weighted (IW) fat-suppressed (fs) spin echo and Dual Echo Steady State (DESS) sequences on 3 T MRI. METHODS Included were 201 ...

Epigallocatechin gallate (EGCG) is a major component of green tea polyphenols having a potent anti-oxidant potential. Besides inhibiting the growth of many cancer cell types and inducing proliferation and differentiation in keratinocytes, it has been shown to promote reduction of body fat. The fact that mesenchymal stem cells (MSCs) have ability to self-renew and differentiate into the cells of...

Objective(s)Tissue engineering is an attractive science because it promises new therapeutic strategies for repairing organs that have lost functions due to damage. The purpose of this study was to evaluate induction effect of human gingival scaffold in tissue engineering for skin regeneration.Materials and MethodsTissue samples were obtained from crown-lengthening procedures and wisdom teeth re...

Obesity is a complex multifactorial disease. Adipocytes arise from pluripotent mesenchymal stem cells (MSC), which are also capable of differentiation into bone, muscle, or cartilage. Adipogenesis involves lineage commitment, mitotic clonal expansion, and terminal differentiation. Understanding these mechanisms, as well as when and how to turn them on or off, may allow development of new therap...

Adipose-derived stem/stromal cells (ASCs) are progenitor cells used in bone tissue engineering and regenerative medicine. Since Bichat's fat pad is easily accessible for dentists and maxillo-facial surgeons, we compared the features of ASCs from Bichat's fat pad (BFP-ASCs) with human ASCs from subcutaneous adipose tissue (SC-ASCs). BFP-ASCs isolated from a small amount of tissue were characteri...
