Atypical Cilia in Human Endometrium
Motile cilia throughout the bios possess a constant number of fibrils which are arranged in a regular and consistent pattern. Yet, during a study on the fine morphological changes of human uterine epithelium in different phases of the cycle, we observed an impressive number of cilia showing a wide variety of structural anomalies previously unreported in a mammalian tissue. Such a conspicuous de...
متن کاملHaemoglobin expression in human endometrium.
BACKGROUND The general concept that haemoglobin is only a carrier protein for oxygen and carbon dioxide is challenged since recent studies have shown haemoglobin expression in non-erythroid cells and the protection of haemoglobin against oxidative and nitrosative stress. Using microarrays, we previously showed expression of haemoglobins alpha, beta, delta and gamma and the haeme metabolizing en...
متن کاملTelomerase activity in human endometrium.
Human uterine endometrium undergoes a complex pattern of changes in proliferation and secretory activity during the menstrual cycle. In the present study, telomerase activity in normal endometrium was examined using a non-radioisotope PCR-based telomeric repeat amplification protocol assay. Various levels of telomerase activity were detected in the 60 normal endometrial samples examined, depend...
متن کاملChromosomes of human endometrium.
Evidence is gradually accumulating about acquired somatic chromosome anomalies, particularly those of neoplasms. Unfortunately, control observations are almost entirely lacking. It is generally assumed that all the tissues of the body consist of cells with the normal karyotype as it is seen in cultured lymphocytes or fibroblasts, but this has not yet been shown to be the case. Even bone-marrow,...
متن کاملOrientation of human respiratory cilia.
Ciliary orientation was studied on the respiratory epithelium of the nasal cavity or the sphenoidal sinus of ten adult nonsmokers without respiratory disease. The ciliary orientation was evaluated from micrographs by measuring the angle between the plane defined by the central tubules and reference line (with a semiautomatic image analyser (IBAS I]. The standard deviation of the angles of cilia...
