Taste receptor cells arise from local epithelium, not neurogenic ectoderm.
Except for taste bud cells, all sensory receptor cells and neurons have been shown to originate from neurogenic ectoderm (i.e., neural tube, neural crest, or ectodermal placodes). Descriptive studies on taste buds indicate that they, however, may arise from local epithelium. To determine whether taste receptor cells originate from neurogenic ectoderm or from local epithelium, the tongues of X c...
متن کاملCancerous stem cells can arise from pediatric brain tumors.
Pediatric brain tumors are significant causes of morbidity and mortality. It has been hypothesized that they derive from self-renewing multipotent neural stem cells. Here, we tested whether different pediatric brain tumors, including medulloblastomas and gliomas, contain cells with properties similar to neural stem cells. We find that tumor-derived progenitors form neurospheres that can be pass...
متن کاملCapsules of the diatom Achnanthidium minutissimum arise from fibrillar precursors and foster attachment of bacteria
Achnanthidium minutissimum is a benthic freshwater diatom that forms biofilms on submerged surfaces in aquatic environments. Within these biofilms, A. minutissimum cells produce extracellular structures which facilitate substrate adhesion, such as stalks and capsules. Both consist of extracellular polymeric substance (EPS), but the microstructure and development stages of the capsules are so fa...
متن کاملThe Probiotic Bacteria Induce Apoptosis in Breast and Colon Cancer Cells: An Immunostimulatory Effect
Background: Uncontrolled cell proliferation and resistance to apoptosis are the main characteristics of cancer cells. Therefore, a substance with the capability to induce apoptosis in cancer cells could be known as an anti-cancer material. Probiotics are useful microorganisms that are crucial for the host’s health.Materials and Methods: In the present stu...
متن کاملStudying the effects of several heat-inactivated bacteria on colon and breast cancer cells
A great number of researches over the last years are allocated to know cancer reasons, prevention and treatment strategies. Bacterial infections are one of the promoting factors in cancer development. The present study was carried out to study effects of heat-killed bacteria on cancer cell lines MCF7 and HT-29. To this purpose, four bacterial strains including Salmonella typhi, Sta...
