objective: to date, several scaffolds have been fabricated for application in bone tissue repair. however, there remains a need for synthesis of scaffolds with better mechanical properties, which can be applied to defects in weight-bearing bones. we constructed a composite ceramic bioscaffold of hydroxyapatite-alumina and silicon carbide (ha-al2o3- sic) to take advantage of the mechanical prope...

Objective Genetic and morphologic similarities between mouse embryonic stem cell (ESCs) and Primordial Germ Cell (PGCs) make it difficult to distinguish the two cell types in in vitro differentiation. Using the expression of specific markers of germ cells that are not expressed or expressed at low levels in ESCs, can help recognizing in vitro differentiated cells MaterialsAndMethods In this stu...

background: adipose-derived stem cells (adscs) are a population of pluripotent cells used for tissue engineering purposes. the main purpose of the present study was to transdifferentiate the adscs to schwann-like cells and to determine the intensity of apoptosis in adscs during the transdifferentiation process.   methods: adscs were isolated from the inguinal adipose tissue of adult rats and th...

background: p19 cells are mouse embryonic carcinoma cells which contain pluripotent ability, like stem cells, to differentiate into different cell lines. there are several properties for this cell line that make it a valuable cell model for study of developmental stages. methods: at the first step, pts2-egfp coding sequence which was cloned in pucd2.hygro vector was used for transfection in to ...

the coexistence of two malignancies is rarely seen. a little association between hematologic malignancies especially multiple myeloma and renal cell carcinoma has been reported in the recent past. several case series revealed a bidirectional association between these two malignancies which may be due to the common risk factors, similar cytokine growth requirements and clinical presentation. her...

cellsderived from wharton’s jelly have been reported to display a wide multilineagedifferentiation potential, showing some similarities to both embryonic (esc)and mesenchymal stem cells (mscs). the present study investigated thedifferentiation potential of human umbilical cord mesenchymal stem cells(ucmscs) into hepatic lineage through embryonic body- like aggregates formationin the presence of...

Background: Neutrophils are the most abundant white blood cells in humans. Recently, a novel strategy called the formation neutrophil extracellular traps (NETs) was described. NETs is a new strategy for pathogen response. This study focused on whether LPS induced NETs release in vitro in the HL60 cell line. Methods: In this study, the HL60 cell line was used for culture and DMSO for induction ...

Background: Endometriosis is the growth of endometrial cells outside the uterine cavity. It has been suggested that immune system plays important roles in both initiation and progression of the disease. Several studies have been shown that women with endometriosis diverge in their expression of different genes including heat-shock proteins, fibronectin, and neutrophil elastase, which might be i...
