Long-term organ culture of human uterine endocervix. Schürch W, McDowell EM, Trump BF. Explants of human endocervix have been maintained in organ culture for 24 weeks.
The epithelium was viable for the entire duration of culture, as demonstrated by ultrastructural morphology and mitotic by: bolic responses to carcinogens ().
Organ culture has the advantage over cell culture in that stromal and epithelial architecture and the normal cellular relationships remain preserved. In this paper we present results of long-term organ culture of the human uterine endocervix. The endo-cervical epithelium was maintained in culture for Cited by: Glycoproteins from normal and malignant human cervix were studied using an organ culture system and compared by gel electrophoresis and autoradiograph Cited by: 5.

This is the portion of the cervix that is • The cervix, the lower fibromuscular portion of the uterus, measures cm in length and cm. PROSTAGLANDINS THE REGULATORY INFLUENCE OF PROSTAGLANDINS ON PROTEIN SYNTHESIS IN THE HUMAN NON PREGNANT CERVIX A.

Although the cervix was recognized as an organ entity as early as B.C. during the third Egyptian Dynasty, it was Soranus, in the first century A.D., who gave the first accurate description of the cervix uteri as a separate portion of the uterus. 48 The cervix (term taken from the Latin, meaning “neck”) is the most inferior portion of the uterus protruding into the upper vagina.
Abstract. The human cervix can today be considered as a separate functional entity within the uterus in comparison with an earlier widespread opinion that this structure merely played a passive role secondarily to contractions of the uterine body.
The cervix is a tubular pathway between the vagina and the uterine body, measuring around 2–3 centimeters in length. The cervix produces mucus, which changes during the menstrual cycle to act as a barrier or a transport medium to sperms dependent on the viscosity of the mucus.
Cervix, uterine. The cervix measures around 2–3 centimeters in length. It is part of the female reproductive system situated between the vagina and the uterine body.
The cervix is composed of fibrous, muscular and elastic tissue lined with columnar and squamous epithelium. bor, the numbers of nerve ﬁbers and levels of neurotrophins and TRPV1 in the human cervix are considerably higher than in the corpus. These ﬁndings lend support to our hypothesis that the cervix uteri is the major site from which labor pain emanates.
Further-more, the sensory corpuscles identiﬁed in the non-distended corpus and cervix. The uterine cervix is a hormonally responsive organ whose function is tightly regulated during pregnancy.
Interstitial collagenase is believed to play a key role in the mechanism of cervical. Human Organ Systems. An organ system is a group of organs that work together to perform major functions or meet physiological needs of the body.
Figure below shows the eleven distinct organ systems in the human body. Assigning organs to organ systems can be imprecise since organs that “belong” to one system can also have functions integral to another system. Human reproductive system - Human reproductive system - The uterus: The uterus, or womb, is shaped like an inverted pear.
It is a hollow, muscular organ with thick walls, and it has a glandular lining called the endometrium. In an adult the uterus is cm (3 inches) long, 5 cm (2 inches) in width, and cm (1 inch) thick, but it enlarges to four to five times this size in pregnancy.

The uterine cervix produces a mucus that aids in carrying sperm from the vagina to the uterus, where it can fertilize an egg if the woman is ovulating.
Glycosylation is the most common and structurally diverse of all the post-translational modifications of proteins. Lipids and extracellular matrices are also often glycosylated. The mammalian uterus is highly enriched in glycoconjugates that are associated with the apical surfaces of epithelial cells and the secretions released by both epithelial and stromal cells.
When estradiol is administered to a mammal, the hormone becomes bound to uterine tissue, where it increases the rates of protein synthesis, of uptake of water and glucose, and, eventually, of growth of the lining epithelium and underlying muscular tissue (endometrium) of the uterus.
Female Reproductive Organs • The Female Reproductive organs comprise: • The Gonads- in the form of two ovaries • The accessory sex organs consisting of • The Fallopian Tube • Uterus • Cervix • Upper end of Vagina 3.

Bieber The uterus, and specifically the endometrium, is a dynamic and ever-changing organ throughout much of a woman's life. The fundamental physiologic processes that occur from menarche to menopause must be well understood by physicians to allow appropriate diagnosis and treatment of underlying disorders.
The endocrine system regulates the growth of the human body, protein synthesis, and cellular replication. A major hormone involved in this process is growth hormone (GH), also called somatotropin—a protein hormone produced and secreted by the anterior pituitary gland.
Its primary function is anabolic; it promotes protein synthesis and tissue. The association between cervical cancer and human papillomavirus (HPV) is well known, but its association with human immunodeficiency virus (HIV) is controversial. Coinfection with HPV and HIV is to be expected and recent epidemiological data from Africa show that cervical cancer is the most common AIDS defining neoplasm in women.
Unlike other AIDS defining neoplasms, the occurrence of.

The placenta takes over the synthesis and secretion of progesterone throughout pregnancy as the corpus luteum degenerates.
Like estrogen, progesterone suppresses FSH and LH. It also inhibits uterine contractions, protecting the fetus from preterm birth. The uterus has three regions: the fundus, the body, and the cervix. It has three layers: the outer perimetrium, the muscular myometrium, and the inner endometrium.
The endometrium responds to estrogen released by the follicles during the menstrual cycle and grows thicker with an increase in blood vessels in preparation for pregnancy. On the protein: estrogen stimulate directly RNA synthesis lead to protein synthesis. progesterone it is production same as estrogen.

Overview. BioChain’s Genomic DNAs are available from different human adult normal tissues. Each organ genomic DNA is from a single donor. Human papillomavirus (HPV) is a non-enveloped protein capsid containing eight genes in a circular, double-stranded DNA genome (Figure 1).
The genes are characterized as either early (E) or late (L) genes. The names are related to when the genes are expressed; e.g. early genes are produced early in the virus life cycle.

Human myometrial smooth muscle cell culture model. Human myometrial samples are obtained from lower uterine segment during elective Cesarean section of singleton pregnancies.
The samples are cleared of serosa, fibrous or damaged tissue. During pregnancy, the uterus enlarges and transforms into a muscular organ sufficient to accommodate the fetus, placenta, and amniotic fluid.
Uterine enlargement results from the stretching and hypertrophy of existing muscle cells and an accumulation of fibrous tissue, most of which is collagen, along with an increase in elastic tissue content.
