Objective(s):To study the effect of low-frequency vibration on bone marrow stromal cell differentiation and potential bone repair in vivo. Materials and Methods:Forty New Zealand rabbits were randomly divided into five groups with eight rabbits in each group. For each group, bone defects were generated in the left humerus of four rabbits, and in the right humerus of the other four rabbits. To t...

Lithium content does not underlie the bioactive effects of LAPONITE® on human bone marrow stromal cell osteogenic activity.

Sertoli cell tumors of the testis are extremely rare tumors with a heterogeneous pathology. Three histological variants have been described: Sertoli cell tumor not otherwise specified (NOS), large cell calcifying sertoli cell tumor and the Sclerosing Sertoli cell tumor. The sclerosing Sertoli cell tumor described herein is associated with prominent stromal sclerosis. They present as painless...

introduction: an induction of osteogenic differentiation in rat bone marrow stromal cell cultures by dexamethasone was reported. materials and methods: the marrow stromal cells obtained from 4 to 6 weeks - old spruge-dawely male rats were grown in primary culture for 7 days and then subcultured for 20 days. the cells were cultured in either dmem medium containing 15% fetal calf serum, antibioti...

Human mesenchymal stem cells (hMSCs), which also called mesenchymal stromal cells, are multipotent stem cell. Human MSCs typically are positive for the surface markers CD44, CD73, CD90, CD105, CD106, and also negative for hematopoietic markers CD34 and CD45.These cells can be isolated from postnatal bone marrow, adipose tissue, placenta, and scalp tissue, as well as from various fetal tissues. ...

background: mesenchymal stromal cells (mscs) are employed in various different clinical settings in order to modulate immune response. human autologous and allogeneic supplements including platelet derivatives such as platelet lysate (pl), platelet-released factors (prf) and serum are assessed in clinical studies to replace fetal bovine serum (fbs). the immunosuppressive activity and multi-pote...

research about potential use of stem cells for the development of germ line cells in vitro had been challenged. in the present study, we reported a novel protocol consisting of cocktail growth factor addition for germ cell differentiation followed by transfection. the cells were purificated based on the expression on the cell surface of a protein. this protein is not present in normal cells of ...

the sex cord-like variant of endometrioid carcinoma is a rare subtype with a close histological resemblance to the sex cord-stromal tumor of the ovaries, in particular the sertoli cell tumor. however, very few cases of the granulosa cell tumor-like variant have been reported since it is commonly misdiagnosed as a granulose cell tumor. immunohistochemistry is useful in the diagnosis of these tum...
