“…Similar to bovine imEECs, the bovine EECs established in this study expressed both an epithelial marker, cytokeratin, and a stromal marker, vimentin (Zhang et al 2013). The acquisition of vimentin by cytokeratin-positive epithelial cells during in vitro culture periods has been reported (Bergh et al 1984;Wang et al 2000;Zeiler et al 2007), which has been explained by a limited epithelial to mesenchymal transition (EMT; Pagan et al 1996). This transition is believed to correlate with a loss of cell-to-cell contacts that result from cell disaggregation during the period of epithelial cell culture preparation (Zeiler et al 2007).…”

Endometrial epithelial cells (EECs) cultured in vitro are valuable tools for investigating embryo implantation and trophoblast differentiation. In this study, we have established the bovine EECs and trophoblast stem-like (TS) coculture system, and used it to investigate the binucleate cell formation of ungulates. The EECs was derived from the uterine horn ipsilateral to the corpus luteum by using collagenase I and deoxyribonuclease I, which exhibited typical epithelial morphology and were expressing bovine uterine epithelial marker such as IFNAR1, IFNAR2, Era, PGR, ESR1 and KRT18. The cells immunostained positively by epithelial and trophectoderm marker cytokeratin 18 (KRT18) and stromal marker vimentin antibodies, and the KRT18 positive cells reached 99 %. The EECs can be cultured for up to 20 passages in vitro with no significant morphology changes and uterine epithelial marker gene expression alteration. The bTS cells were established in a dual inhibitor system and exhibited typical trophoblast stem cell characteristics. When bTS cells were cultured with EECs, the bTS cells adhered to the EECs as adhering to feeder cells. Binucleate cells began appearing on day 4 of coculture and reached approximately 18.47 % of the differentiated cells. Quantitative real-time PCR or immunofluorescence analyses were performed on bTS cells cocultured at day 6 and day 12. The results showed that the expression level of KRT18 was down-regulated while the expression level of trophoblast differentiation marker MASH2, HAND1, GCM1 and CDX2 was upregulated in bTS cells. In conclusion, bovine EECs can be obtained from the uterine horn ipsilateral to the corpus luteum via treatment with collagenase I and deoxyribonuclease I, and the EECs-bTS cells coculture system presents an ideal tool for studying the differentiation of bTS cells to trophoblast binucleate cells.

“…Figure 3C and F shows the coexpression of cytokeratin and vimentin in three passages of the WHI cells. The expression of vimentin filaments along the preexisting filament network has been reported in the epithelial-tomesenchymal transition of neonatal rat hepatocytes in culture (7). In the NIH cells, the majority of the cells expressed only vimentin, whereas there were some epithelial cells that expressed only cytokeratin (Fig.…”

Limited organ availability is an obstacle to the widespread use of islet transplantation in type 1 diabetic patients. To address this problem, many studies have explored methods for expanding functional human islets in vitro for diabetes cell therapy. We previously showed that islet cells replicate after monolayer formation under the influence of hepatocyte growth factor and selected extracellular matrices. However, under these conditions, senescence and loss of insulin expression occur after >15 doublings. In contrast, other groups have reported that islet cells expanded in monolayers for months progressed through a reversible epithelial-to-mesenchymal transition, and that on removal of serum from the cultures, islet-like structures producing insulin were formed (1). The aim of the current study was to compare the two methods for islet expansion using immunostaining, real-time quantitative PCR, and microarrays at the following time points: on arrival, after monolayer expansion, and after 1 week in serum-free media. At this time, cell aliquots were grafted into nude mice to study in vivo function. The two methods showed similar results in islet cell expansion. Attempts at cell differentiation after expansion by both methods failed to consistently recover a ␤-cell phenotype. Redifferentiation of ␤-cells after expansion is still a challenge in need of a solution. Diabetes 56: 703-708, 2007

“…The chromatin-remodeling hSNF5/INI1 gene at 22q11.2 has been reported in some MRT (26). The hSNF5/INI1 inactivation is mainly associated with homozygous deletions and mitotic recombinations (27 (30). Otherwise, in rhabdomyosarcoma and alveolar soft-part sarcoma, desmin and vimentin are colocalized within the same cells (31).…”
