Relaxin and the Human Fetal Membranes
Reproductive Sciences, 2007The human fetal membranes are complex tissues that perform many important functions during gestation. The extracellular matrix provides their strength to withstand the forces directed from the fetus and myometrium. Relaxin is a collagenolytic hormone that causes increased production of the matrix metalloproteinases.

Development of Fetal Membranes
1971During the first week of development, the following structures appear in succession (fig. 1): — the trophoblast, by differentiation of the superficial cellular layer of the fertilized egg. (Since the trophoblast gives rise to the placenta, it will be studied with this organ, pp.

Fetal weight and membrane tensile strength
American Journal of Obstetrics and Gynecology, 1964Abstract 1. 1. The tensile strength per unit width of membranes was studied in 62 cases of premature delivery and late abortion, 27 cases of premature rupture of the membranes, and 101 normal term deliveries. 2. 2. The average tensile strength of the membranes from normal term deliveries was 0.207 Kg.

Premature Rupture of the Fetal Membranes
New England Journal of Medicine, 1998The membranes surrounding the amniotic cavity are composed of the amnion and the chorion, which are closely adherent layers consisting of several cell types, including epithelial cells, mesenchymal cells, and trophoblast cells, embedded in a collagenous matrix.

Cathepsins B1 from human fetal membranes
Biochimica et Biophysica Acta (BBA) - Enzymology, 1976Cathepsins B1 (EC 3.4.22.1) were isolated from fetal membranes of human placenta, i.e. amnion and chorion-decidua. Purification of the enzymes was achieved by the freezing-thawing technique, ammonium sulphate fractionation and Sephadex gel filtration. Cathepsis B1 separated either from amnion or from chorion-decidua exhibited optimum activity at pH 6.2,

Observations of Human Fetal Otoconial Membranes
Annals of Otology, Rhinology & Laryngology, 1979Intact otoconial membranes from 31 human fetuses ranging in gestational age from 14 to 36 weeks were studied. At all stages of development specimens from different individuals showed marked variations in overall shape. During the course of the second and third trimesters, both saccular and utricular otoconial membranes were found to increase three to ...

Fetal Membranes-Derived Stem Cells Microenvironment
2017Recently, the regenerative medicine has been trying to congregate different areas such as tissue engineering and cellular therapy, in order to offer effective treatments to overcome several human and veterinary medical problems. In this regard, fetal membranes have been proposed as a powerful source for obtainment of multipotent stem cells with low ...

Fetal Membrane Adhesions and Congenital Malformations
1972A group of congenital malformations exists in which fibrous bands of amniotic origin are found to be attached to the malformed parts of the fetus or newborn; these bands are sometimes associated with amputations of fingers, toes or limbs. This type of malformation, which is called “Amniotic-band Syndrome”(1), is not rare. In 1968 Torpin (2) was able to

Premature Rupture of Fetal Membranes
Clinical Pediatrics, 1966The study here described represents another attempt to estimate under con trolled conditions the value of prophylac tic treatment with antibiotics for normal infants born to otherwise healthy moth ers after premature rupture of the am niotic membranes.
