Abstract
A cell line was derived from midgestation chorioallantoic placental explants of the outbred Holtzman rat. The cell line was found to express characteristics of extraembryonic membranes and to grow when introduced into allogeneic hosts. Growth in allogeneic hosts was detected following intraperitoneal injection of the cells but not following subcutaneous injection. The transplanted cells grew as cystic structures free in the peritoneum and as solid masses adhered to various abdominal organs. Cystic structures had a homogeneous morphology consisting of an epithelial-like cell layer surrounding a fluid-filled sac. Solid masses had a heterogeneous morphology, containing parts resembling normal components of the extraembryonic membranes (trophoblast, parietal, and visceral yolk sacs). Biochemical analysis of the placenta-derived cell line and transplanted structures derived from the cell line indicated that the cells had the potential to produce a variety of proteins characteristic of extraembryonic tissues. Cultured cells and both types of in vivo transplants produced the basement membrane protein, laminin. Peritoneal cystic structures also contained alpha-fetoprotein mRNA and very high levels of c-fos mRNA. Solid masses demonstrated elevated alkaline phosphatase activity, a marker of trophoblast cells. Cells grown in vitro expressed elevated c-myc mRNA levels, whereas, c-myc mRNA levels were reduced in the in vivo transplants. The behavior of the cell line in vitro and following in vivo transplantation suggests it contains elements capable of differentiation toward various components of the extraembryonic membranes. The results indicate that the rat placental cell line will be valuable for future studies on the differentiation of trophoblast cells and other components of the extraembryonic membranes.

Abstract
Long-term culture of placentas obtained from the mating of a congenic C3H male mouse carrying a unique electrophoretic variant of the X-chromosome-linked enzyme phosphoglycerate kinase (PGK-1) and a normal C3H female mouse has resulted in cell lines that have apparently undergone spontaneous malignant transformation in vitro. When injected into normal syngeneic animals, these cell lines have given rise to invasive carcinomas of two distinct histologic types, an adenocarcinoma and a poorly differentiated carcinoma. Both were demonstrated to be of placental origin by the continued presence of the allozyme coded on the paternal X-chromosome. Compared to murine tumors of other etiologies, these cell lines were characterized by a high intracellular alkaline phosphatase concentration.

Abstract
Normal human placenta and amnion from the 20th week of pregnancy were transplanted into nude mice. The transplants retained the histological and immunohistochemical picture of the original tissue and maintained synthesis of human chorionic gonadotropin (hCG), pregnancy-specific beta 1-glycoprotein (SP1), GnRH and placental proteins PP5, PP11 and PP12 for 5 weeks. This experimental model has a wide potential application for studies on placental protein synthesis and the hormonal influence of human placenta on other simultaneously transplanted human tissues.

Abstract
Abstract.
Rat placental extracts (rPE) were investigated in bioassays for their possible content of rat placental lactogen (rPL) and rat chorionic gonadotrophin (rCG). Luteotrophic and lactogenic activity of rPL was assessed by substitution of rats depleted of endogenous prolactin (Prl) by means of bromoergocryptine (BEC) in early pregnancy and the period of lactation, respectively. The abortifacient effect of a single dose of BEC on day 6 of pregnancy was abolished by rPE equivalent to 1 g rat placenta corresponding to 5 IU bovine Prl (NIH-P-B 2). Substitution was necessary until the evening of day 7 indicating that rPL does not take over the function of Prl before day 8. During lactation rPE reversed the lactation inhibiting effect of daily BEC treatment. In this assay rPL activity corresponded to 1.25–2.5 IU bPrl/g placenta.
In order to test for the possible existence of rCG the gonadotrophic activity of rPE was assessed in immature female mice. No gonadotrophic activity was found when rPE equivalent to 1 g rat placenta was administered, whereas equivalents of 3 mg human placenta and 12 mg rat pituitary entailed a dose-dependent response. In this system 0.12 IU human chorionic gonadotrophin (hCG), which served as standard, was the minimal dose (MD) resulting in increased uterine weight.
In addition rPE was tested in the immature female rat, where the limit of detection was found to be 0.5 IU hCG. Again no gonadotrophic activity was found in rPE. As the effects of rCG might have been restricted to its presumed target, the corpus luteum of pregnancy, rPE was also tested in pregnant rats depleted of endogenous luteinizing hormone (LH) by a single injection of anti-LH antibodies on day 10 of pregnancy. A MDof 0.5 IU hCG, which served as standard, prevented resorption of foetuses in all animals tested. rPE equivalent to 3.5 g rat placenta, rat pregnancy serum of day 18 and placental transplants could not substitute for endogenous LH.

Abstract
Immunological interrelations between placenta and kidney have become a matter of interest with regard to the pathogenesis of preeclampsia. Kidney morphology of Lewis rats was studied following repeated transplantations of heterologous or syngeneic placental tissue. In most of the heterologous placenta-recipient animals, diffuse severe glomerular lesions were found, similar to those seen in women with preeclampsia. In the strongly responding recipients, endothelial cell swelling, narrowing of capillary lumina and proliferation of mesangial matrix were observed. Patchy areas of fluorescence associated with dense IgG deposition, as well as fibrin deposits demonstrated in the affected glomeruli, were correlated with histologic changes. The use of syngeneic placenta as a transplant did not cause histological or immunohistological changes. These findings support the view that differences in histocompatibility antigens between mother and fetus may be involved in the pathogenesis of the nephropathy in preeclampsia.

Abstract
A review of the current theories on the nature of the placental allograft and the evolution of placentation in the presence of a cellular immune response highlights the inability of current hypotheses to explain the success of both invertebrate and vertebrate placentation. Only one theory -- "the anatomical separation of the fetus from the mother" -- appears relevant. How this separation might develop during implantation is discussed.

Abstract
A genetic mutation in mice (W/Wv) causes an autosomal recessive disease characterized by hypoplastic anemia which lasts throughout life. Double-dominant W/Wv anemic mice were sublethally irradiated to facilitate repopulation of marrow with transplanted cells and were injected intravenously with suspensions of 5-10 million placental cells of 15 days gestation derived from normal, isogeneic donors. Red cell counts fell promptly after irradiation and then rose progressively over a period of weeks, reaching normal levels of the nonmutant. Mean corpuscular volume and hemoglobin electrophoresis patterns of red cells in recipient W/Wv mice resembled those of normal donor animals. The therapeutic effect lasted for the duration of the observation period, in some instances over 9 mo. W/Wv mice that were administered Hanks' solution or fetal blood, instead of placental transplants, remained anemic. Late gestation placentas (18 days) were also ineffective.

Abstract
SUMMARY
Mammotrophic (i.e. mammogenic and/or lactogenic) activity of mouse placentae of different stages (4–19 days of pregnancy) was examined using organ co-culture of placental explants with mammary tissue. The test mammary tissues were taken from midpregnant (11–12 days) nulliparous A/Crgl mice and cultured in a synthetic medium (Waymouth's) supplemented with insulin (5 μg/ml) and aldosterone (1 μg/ml). The responses of mammary gland to placental explants were judged histologically, and were compared with those seen after the addition of ovine prolactin (5 μg/ml). With placentae from 6- to 19-day pregnant animals, distinct mammotrophic activity was seen, with the appearance of eosinophilic secretion in the mammary alveolar lumina, whereas with 4- or 5-day-old 'placentae', no mammotrophic activity was detected. Inasmuch as growth hormone does not substitute for prolactin in mammary gland development and function in the A/Crgl mouse, it can be concluded that a prolactin-like factor is present in the mouse placenta. The influence of placentae on mammary gland was further analysed by transplantation of placental fragments to mammary fat pads. Local lobuloalveolar development was prominent in some instances in the area around the placental transplants.
