The low-affinity nerve growth factor receptor p75 is a stratified epithelial stem/progenitor marker of human epithelia. We found OM-1, squamous cell carcinoma (SCC) line, showed distinct cells with cluster, especially located at the center growing colony in monolayer culture. A cluster was surrounded by cytokeratin 14- and 13-expressing that settled outer margin colony. OM-1 were also capable f...

OBJECTIVE To evaluate the damaging effects of cisplatin on MMSCs from adipose tissue in a phase of active proliferation and the state of the monolayer, this was exposed at standard (20%) and reduced to 1% and 5% level of oxygen. METHODS The effect of cisplatin was detected on monolayer cultures in the active growth phase after 2 passages. Profile surface markers of MMSC was determined by flow...

objective: human retinal pigment epithelium (hrpe) is a cell monolayer located in the outer part of the retina that is in contact with photoreceptors. in many diseases rpe cells damage. one way for treating this disease is the implantation of intact instead of damaged cells. for this reason different types of substrates have been used for cell cultivation. this study has used alginate and a ble...

Human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs) provide an unlimited source for the generation of human hepatocytes, owing to their indefinite self-renewal and pluripotent properties. Both hESC-/iPSC-derived hepatocytes hold great promise in treating liver diseases as potential candidates for cell replacement therapies or as an in vitro platform to conduct new drug...

Several protocols have been developed for human induced pluripotent stem cell neuronal differentiation. We compare several methods for forebrain cortical neuronal differentiation by assessing cell morphology, immunostaining and gene expression. We evaluate embryoid aggregate vs. monolayer with dual SMAD inhibition differentiation protocols, manual vs. AggreWell aggregate formation, plating subs...

This study was designed to examine the effects of retinoic acid adding to cumulus and/or fibroblast cellsmonolayer on the development of mouse early embryos. One-cell mouse embryos were obtained from NMRImice after superovulation by an intraperitoneal injection of 5 IU equine chorionic gonadotrophin (eCG)followed 48 hrs later by 5 IU human chorionic gonadotrophin (hCG). Mouse embryonic fibrobla...

BACKGROUND While articular chondrocytes are among those appropriate candidates for cartilage regeneration, the cell dedifferentiation during monolayer culture has limited their application. Several investigations have indicated the usefulness of alginate, but the topic of proliferation and differentiation of chondrocytes in alginate culture has still remained controversial. METHODS Rat articu...

Monolayer and suspension cell cultures prepared from Hodgkin's disease tumors in the spleen were examined microscopically and by cytogenetics, tested for lymphocyte and monocyte cell surface properties, and assayed for enzymes by histochemical and spectrophotometric techniques. Hodgkin's disease monolayer cultures were composed of rapidly proliferating round and polygonal cells that were capabl...

Buffalo ovaries were collected from a slaughter house and cumulus cells oocytes complexes (COCs) were recovered for preparation of 2-D, 4-D, 6-D and 8-D monolayer. Cumulus cells were stripped off by repeated pipetting into TCM-199 medium supplemented with 10% FCS. Approximately 2x106/ml cumulus cell were transferred in 100 μl drops of culture medium and incubated in humidifi ed atmosphere of 5%...
