introduction: this study was designed to investigate the characters of the human endometrial epithelial cells when cultured on either plastic or ecm (extracellular matrix) gel surface and to study ultrastructural features of cultured cells in comparison to endometrial tissue. material and methods: human endometrial tissue was obtained from patients who had undergone hysterectomy for uterine myo...

BACKGROUND Eukaryotic chromosomal ends are linear and are protected by nucleoprotein complexes known as telomeres. The complex structural anatomy and the diverse functions of telomeres as well as the unique reverse transcriptase enzyme, telomerase that maintains telomeres are under intensive scientific scrutiny. Both are involved in many human diseases including cancer, but also in ageing and c...

Undifferentiated/dedifferentiated endometrial carcinomas (UCE/DCEs) of the endometrium are rare tumors with poor prognosis. There are few clinicopathologic studies with detailed immunohistochemical analysis regarding UCE/DCEs.We evaluated the diagnostic value of a selected tumor stem-cell marker and epithelial-mesenchymal transition (EMT) markers, in addition to previously studied markers in id...

Candidate stem/progenitor cells have been identified in mouse endometrium as label-retaining cells (LRCs). The role of endometrial stem/progenitor cells in initiating estrogen-stimulated endometrial growth in prepubertal and cycling mice was investigated following a single 17β-estradiol (E2) injection in bromodeoxyuridine (BrdU)-labeled and -chased (LRC), ovariectomised mice. Proliferating (Brd...

The majority of ovarian, endometrial, and breast cancers express gonadotropin-releasing hormone (GnRH) receptors. Apart from reproductive organs (ovaries, fallopian tubes, and uterus) that are normally removed during surgical therapy of ovarian or endometrial cancer, pituitary gonadotrophs also express GnRH receptors. The signal transduction pathway in tumor cells is basically different from th...

objective: the aim of this study was to estimate the cheminformatics and qualitative structure-activity relationship (qsar) of cinnamaldehyde and eugenol. the effects of cinnamaldehyde and eugenol on the viability, doubling time and adipogenic or osteogenic differentiations of human adipose-derived mesenchymal stem cells (hascs) were also investigated.  materials and methods: qsar and toxicity ...

objective(s): in order to grow cells in a three-dimensional (3d) microenvironment, self-assembling peptides, such as puramatrix, have emerged with potential to mimic the extracellular matrix. the aim of the present study was to investigate the influence of the self-assembling peptide on the morphology, survival, proliferation rate, migration potential, and differentiation of human meningioma st...

objective: menstrual blood stromal stem cells (mbscs) share some phenotypic and functional similarities with mesenchymal stem cells (mscs). mscs are shown to inhibit either the function or generation of different immune cells, including dendritic cells (dcs). however, data regarding mbscs’ potential effects on immune system cells are elusive. here, we examine whether mbscs affect the generation...
