Introduction: Amniotic membrane, the innermost layer of extra-embryonic tissue, contains mesenchymal and epithelial stem cells. The amniotic mesenchymal cells have the capability of inhibition of growth of cancer cells. In this research, the effects of amniotic epithelial cells on the viability of cancer cells and the role of apoptosis in this procedure were evaluated. Methods: Amniotic mem...
Purpose: The objective for this study is to investigate the morphology and ultrastructure of mouse endometrial epithelial cell monolayer cultured on matrigel in dual-chambered system as an in vitro mouse endometrial epithelial cell culture model that mimics structural and functional properties of the endometrial epithelium in vivo. Materials and Methods: Mouse endometrial epithelial cells were...
Hofírek B. , D. Haas: Comparative Studies of Ruminal Fluid Collected by Oral Tube or by Puncture of the Caudoventral Ruminal Sac. Acta Vet. Brno 2001, 70: 27-33. Samples of ruminal fluid were collected in four groups of high-producing dairy cows simultaneously by an oral probe and by percutaneous puncture of the caudoventral ruminal sac. The samples were tested for basic indicators of the metab...
background and objective: smoking can be associated with the decreasing gingival blood flow and epithelial changes. the aim of this study was to evaluate the histopathological changes of gingival epithelium and connective tissue in smokers. methods: the study was case-control. sixty male patients (28 smokers and 32 nonsmokers) suffering chronic periodontitis were participated in the study. peri...
BACKGROUND Long-term high-concentrate diet (HCD) feeding can cause subacute ruminal acidosis in cows and subsequently trigger systemic inflammatory and immune responses. Therefore, we conducted the present study in which twelve lactating cows installed with ruminal fistula were randomly assigned to the HCD group (forage:concentrate = 4:6, n = 6) or the low-concentrate diet (LCD) group (forage:c...
Spontaneous Mesenchymal to Epithelial Like Tissue Transition (MET) in a Long Term Human Skin Culture
In an attempt to isolate multipotent stem cells from foreskin in a long-term culture, we encountered an interesting phenomenon which was the conversion of the fibroblast dominant condition to epithelial-like tissue formation. However, the basic mechanism(s) which may be involved in this conversion is not clear. This study was designed to evaluate the cells protein secretion activity and examine...
Responses to sugars in dry or liquid form vary from study to study. To explain some of this variation and prioritize when sugars are more likely to have a benefit in diets for high producing dairy cattle, microbial function that influences susceptibility to low ruminal pH or a limitation in growth factors needed for efficient ruminal fiber degradation is discussed in this paper. When fed in pro...
