Abstract
The luteal-placental shift is an important milestone of mammalian pregnancy signifying when endocrine control of pregnancy shifts from the corpus luteum of the ovary to the placenta. The corpus luteum is maintained by chorionic gonadotropin (CG). Upon sufficient placental maturation, CG production wanes, the corpus luteum involutes, and control is shifted to the placenta, one consequence of which is a midgestational rise in glucocorticoid production, especially cortisol and cortisone, by both mother and fetus. Glucocorticoids are involved in initiating parturition, prenatal programming of offspring phenotype, and maturing fetal organs. Limited evidence from human pregnancy suggests that the timing of this shift is delayed in twin pregnancies, but little is known about the timing of the luteal-placental shift in litter-bearing monkeys from the primate family Callitrichidae. Here we provide evidence from cotton-top tamarins (Saguinus oedipus) and common marmosets (Callithrix jacchus) of longer duration of elevated CG associated with multiple infant births compared to single births. Urinary profiles from cotton-top tamarins demonstrate that the decline of the extended elevation of CG precedes the onset of the midpregnancy sustained rise in glucocorticoids; this shift occurs later with an increase from one to two fetuses carried to term. In the common marmoset, the onset of the sustained rise of glucocorticoids in maternal urine is also delayed with an increase in infant number. Total urinary glucocorticoid levels during the last half of gestation increase monthly but do not differ by infant number. The significant delay in the luteal-placental shift suggests a longer period of placental maturation is needed to support a greater number of fetuses.

Abstract
Progesterone (P4) and glucocorticoid (GC) play crucial roles in the immunoregulation of a mother to accept and maintain a semi-allogenic fetus. P4 concentration increases during pregnancy and becomes much higher in the placenta than in the other peripheral tissues, wherein the concentration of cortisol (COR), the most abundant GC and a strong immunosuppressor, remains uniform throughout the rest of the body. Here, we evaluated the effect of a high-P4 environment on pregnant immunity by comparing it with COR. Naïve T cell proportion increased transiently in peripheral blood of pregnant women just after delivery and decreased after one month. T cells stimulated with superantigen toxic-shock-syndrome-1 (TSST-1) in the presence of P4 stayed in the naïve state and did not increase, irrespective of the presence of COR, and reactive T cells could not survive. Treatment of T cells with P4 without T cell receptor (TCR) stimulation transiently suppressed T cell activation and proliferation, whereas the levels remain unaltered if P4 was not given before stimulation. Comparison of the engraftment and response against specific antigens using hu-PBL-NOG-hIL-4-Tg mice showed that P4-pretreated lymphocytes preserved CD62L expression and engrafted effectively in the spleen. Moreover, they produced antigen-specific antibodies, whereas COR-pretreated lymphocytes did not. These results suggest that a high-P4 environment suppresses T cell activation and induces T cell migration into lymphoid tissues, where they maintain the ability to produce anti-pathogen antibodies, whereas COR does not preserve T cell function. The mechanism may be pivotal in maintaining non-fetus-specific T cell function in pregnancy.

Abstract
Endocrine data and characteristics of nonconceptive ovarian cycling and pregnancy are limited within the genus Callithrix to the common marmoset (C. jacchus) and Wied's black tufted-ear marmoset (C. kuhlii). This article presents patterns of urinary pregnanediol-3-glucuronide (PdG) excretion, as determined by enzyme immunoassay, throughout the course of ovarian cycling and pregnancy in white-faced marmosets (C. geoffroyi). Furthermore, characteristics of reproductive parameters including litter size, duration of gestation, maternal age, and information about ovarian cycling following administration of contraceptives are also described. A steep increase in PdG, an indication of ovulation, characterizes normative ovarian cycles, with peak-to-peak intervals between cycles being 27.82 ± 1.49 days in length. PdG excretion (μg/mg Cr) across pregnancy peaked during the 1st and 2nd trimesters (1st = 20.71 ± 2.98, 2nd = 21.16 ± 2.60) and declined gradually to near preconception levels over the 3rd trimester until parturition (3rd = 5.74 ± 1.60). Gestation lasted 148.55 ± 1.89 days. Most pregnancies (82.8%) resulted in an immediate postpartum ovulation (PPO) of 17.45 ± 2.22 days with 58.3% of PPOs resulting in conception. No differences in PdG excretion during the 1st trimester between full pregnancies and miscarriages were found, and pregnancy characteristics such as litter size, duration of gestation, and maternal age were not associated with PdG concentrations. Administration of cloprostenol resulted in shorter peak-to-peak cycle durations, but ovulation was detectable with similar concentrations of peak PdG to a normal nonconceptive cycle. Conversely, medroxyprogesterone acetate (DMPA) injections resulted in little to no PdG excretion across the ovarian cycle. Both methods of contraception providing effective prevention of conception. Overall, these results show that strong similarities in reproductive parameters persist within the genus Callithrix and to a lesser extent across the Callitrichidae family.

Abstract
In early pregnant primates, relaxin (RLX) is highly upregulated within the corpus luteum (CL), suggesting that RLX may have an important role in the implantation of the blastocyst. Therefore, the aim of the present study was to investigate the local effects of RLX and gonadotrophins on the maintenance of the CL using an in vitro microdialysis system. CLs of common marmoset monkeys were collected by luteectomy during different stages of the luteal phase and early pregnancy. Each CL was perfused with either Ringer's solution alone or Ringer's solution supplemented with either porcine RLX (250, 500 and 1000 ng/ml) or gonadotrophins (50 IU/ml). Application of RLX provoked a significant luteal response of progesterone (P(4)) and oestradiol (E(2)) secretions during the mid-luteal phase (500 ng/ml: P(4) 54+/-42%, E(2) 24+/-11%; 1000 ng/ml: E(2) 16+/-13%), and especially during the late luteal phase (250 ng/ml: P(4) 53+/-10%; 500 ng/ml: P(4) 44+/-15%; 1000 ng/ml: P(4) 62+/-15%, E(2) 18+/-7%). The effects of RLX on steroid secretion were irrespective of the RLX dosages. While treatment with human chorionic gonadotrophin did not affect luteal steroid or RLX secretion, the application of FSH resulted in a significant increase in the secretion of both P(4) (20+/-8%) and E(2) (37+/-28%), and a prominent rise in RLX during early pregnancy. In conclusion, our results demonstrate that RLX and FSH have a luteotrophic function in the marmoset monkeys; moreover, FSH has a function beyond its traditional role just as a follicle-stimulating hormone.

Abstract
Maternal hormones can dramatically modify offspring phenotypes via organizational actions on morphological and behavioral development. In placental mammals, there is the possibility that some portion of hormones in maternal circulation may be derived from fetal origin. We tested the possibility that maternal androgens in pregnant female marmosets reflected, in part, contributions from male fetuses by comparing levels of urinary androgens across pregnancy in females carrying varying numbers of male offspring. We monitored urinary androgen excretion in 18 pregnancies from five female white-faced marmosets (Callithrix geoffroyi). Androgen levels rose significantly in the first trimester of pregnancy, reached a peak in the middle of the second trimester, and then declined gradually until parturition. At no point in pregnancy were levels of urinary androgens higher in females carrying litters that had 50% or more males than in females carrying litters that were less than 50% male. Levels of maternal androgens were not associated with litter size, the number of males in the litter, or with the proportion of the litter that was male. The high levels of androgen in pregnant females are therefore likely of strictly maternal origin, and any modification of fetal growth and development can be considered a 'maternal effect'.

Abstract
BACKGROUND Because of its small size and unproblematic captivity behavior the marmoset monkey is an attractive New World primate model for early developmental questions. However, superovulation protocols used in Old World monkeys and women are not successful in the female marmoset. A novel protocol is needed to utilize these New World monkeys as an efficient animal model for in vitro fertilization experiments or embryo stem cell research. METHODS To create such a protocol we first examined the effects of long-term estrous cycle control, secondly, in a dose-finding study, we determined the length of a down-regulation protocol with a gonadotropic releasing hormone (GnRH)-antagonist. Twenty-nine female marmosets were grouped according to the number of estrous cycles, which had been controlled for a period of 12 months in which 88 cycles were monitored. Application of PGF2alpha in the mid-luteal phase led to immediate onset of the follicular phase. The blood progesterone concentration rapidly declined and increased again on day 9-11. RESULTS The results show that the controlled ovarian cycle length and progesterone response are not altered by the number of PGF2alpha injections. The rapid decline was similar in all groups, indicating that all animals, independent of the number of controlled cycles, react equally to multiple PGF2alpha injections. To determine the proper dosage for a GnRH-antagonist (Cetrorelix), 12 animals in three groups of four female marmosets were treated with two different dosages and a sham dosage. Cetrorelix was applied in the mid-luteal phase, three times over 2 days. In both Cetrorelix-treated animal groups the early progesterone levels matched those in the controls. In the low-dose treatment group [0.01 mg/100 g body weight (BW)] the expected progesterone rise on day 10 was delayed between 9 and 15 days whereas in the high-dose treatment group (0.1 mg/100 g BW) the progesterone rise was delayed between 21 and 41 days. In the low-dose group the steepness of the slope from day 20 onwards was almost identical to that of the control group. This was reflected in the bioCG levels measured. CONCLUSIONS Based on the GnRH-antagonist studies, complete ovarian down-regulation in female marmosets can be achieved by applying a low-dose regimen, and intrinsic gonadotropins would not interfere with an ovarian superstimulation protocol.

Abstract
In contrast to the known rodent enzymes, the physiological significance of 17beta-hydroxysteroid dehydrogenase type 7 (17HSD7) and its presumed function in reproductive biology is not well understood in primates. As a first step, we recently cloned the complete coding regions of human and marmoset monkey (Callithrix jacchus) 17HSD7 (cj17HSD7). In the present work the complete cDNA of marmoset 17HSD1 (cj17HSD1), including the proximal promoter region, and a partial sequence of marmoset aromatase (cjARO) were sequenced in order to compare the expression of these estradiol synthesizing enzymes with that of 17HSD7 in a primate model and to identify tissues where 17HSD7 might participate in the pathway of estradiol synthesis. The gene structures of cj17HSD1 and cj17HSD7 were determined and proved to be very similar to the human orthologues. Northern hybridization showed that cjARO mRNA seems to be coexpressed preferably with cj17HSD1 in placenta, whereas in other tissues it is expressed in parallel only with cj17HSD7. Especially in corpora lutea, the cj17HSD7 transcript is detectable throughout the luteal phase of the ovarian cycle and increases during pregnancy, in parallel with the transcript of aromatase. Results were confirmed by immunoblots and immunohistochemistry using new polyclonal antisera directed against cj17HSD7 and cjARO protein. The enzymatic conversion of estrone to estradiol was assessed in marmoset corpora lutea. The pattern of coexpression with aromatase supports the hypothesis that luteal 17HSD7 complements placental 17HSD1, ensuring continued estradiol synthesis throughout pregnancy in primates.

Abstract
The common marmoset monkey (Callithrix jacchus) was used as a primate model for the study of the expression of the estradiol synthesizing enzymes 17beta-hydroxysteroid dehydrogenase type 1 and type 7 (17HSD1 and 17HSD7). The tissue-specific expression of 17HSD1 and 17HSD7 mRNA in Callithrix jacchus and human as shown by Northern Blot analysis revealed strong similarities between the two species. After cloning of the marmoset-specific coding cDNA sequence of 17HSD7 a similarity of 95% to the known human sequences was found. To elucidate the physiological function of 17HSD7 which is thought to be different to that of the well-known 17HSD1, the regulation of 17HSD7 expression in the corpus luteum was investigated. It was shown to be upregulated during the luteal phase of the reproductive cycle and during early pregnancy, when the primate corpus luteum is most active in estradiol synthesis, whereas 17HSD1 was not detectable in this tissue at any time.

Abstract
Estrone-conjugates (E1C) were measured in the feces of six female pygmy lorises (Nycticebus pygmaeus) during estrus (n = 12), pregnancy (n = 4) and the postpartum period (n = 3). Noninvasive feces collection permitted frequent sampling throughout estrus and pregnancy, without disturbance of animals. The estrous period was defined as an increase in fecal E1C levels above an average of 70 ng/g feces with peaks above 100 ng/g feces obtained in consecutive fecal samples collected over a 6- to 11-day period between the end of July and the first third of October. Comparison of the periovulatory profile of E1C and the stage of labial opening of the vagina revealed a high agreement (P < 0.001). In all pregnant females, an E1C rise was found approximately 47 days postestrus, the source of which may be the growing fetal placental unit. Estimated gestation lengths ranged between 187 and 198 days (n = 4).

Abstract
This study was initiated to examine the early stages of trophoblast adhesion and invasion during implantation in the marmoset. Seven implantation sites were found in the uteri of four marmosets taken between days 13 and 15 of gestation. Three implantation sites in two uteri were examined in detail by electron microscopy. Between days 13 and 15, the marmoset implantation site expanded peripherally by adding areas where syncytial trophoblast penetrated between uterine luminal epithelial cells. Such penetrating masses often bridged openings of endometrial glands, shared junctional complexes with the uterine epithelial cells between which they are infiltrating, and subsequently reached the residual basal lamina of the uterine luminal epithelium. Centripetal to the peripheral region was an intermediate region in which syncytial trophoblast overlay individual clusters of epithelial cells and rested along the basal lamina. In this region there was some evidence of fusion of syncytial trophoblast with uterine epithelial cells. In the central region of the implantation site near the inner cell mass and amnion the trophoblast formed elaborate lamellipodia in relation to the basal lamina. In one of the three specimens examined with electron microscopy there were two foci where trophoblast penetrated through the basal lamina. It was also in the central region that trophoblast penetrated farthest into the uterine glands. The gland cells closest to trophoblast were less closely associated and lost their columnar shape, forming large round cells similar to the epithelial plaque cells of other primates. Where two blastocysts implanted on the same side of the uterus a conjoint membrane was formed which in regions consisted solely of syncytial trophoblast with two basal surfaces and two basal laminas. The prolonged period of time when the implantation site expands within the plane of the uterine epithelium (trophoblastic plate stage) and the peripheral to central sequence in extent of development make this primate a particularly useful animal for studies of trophoblast adhesion to and penetration of the uterine luminal epithelium.

Abstract
It has been postulated that carbohydrates are involved in a variety of cell-cell interactions including blastocyst implantation. In primates, there are only limited investigations on the ultrastructural localisation of the cyclic changes in uterine epithelial surface carbohydrates. Our aim was to investigate such changes during the pre-ovulatory and pre-implantation stages of the reproductive cycle in the marmoset monkey. After fixation of endometrial tissues, avidin-ferritin lectin cytochemistry was employed for apical surface glycan detection at the ultrastructural level. Five lectins were used including Canavalia ensiformis (Con A), Lotus tetragonolobus (LTA), Glycine max (SBA), Phytolacca americana (PWM) and Triticum vulgaris (WGA). Morphometry was used to quantitate changes in the intensity of lectin staining by determining the total number of ferritin particles per unit length of membrane. Surface and intra-cytoplasmic vesicles, stained by the lectins, were also examined. Quantitative ferritin assessment showed that 1 day before presumed implantation (days 11 to 12 after ovulation in the marmoset monkey) there was a significant increase in Con A, LTA and SBA staining on the apical uterine epithelial plasma membrane compared to the pre-ovulatory phase and earlier stages of pregnancy (days 4-8 after ovulation). A significant increase in PWM was also detected from early pregnancy to pre-implantation stages. All lectins except WGA produced reproducible staining within reproductive cycle groups. The greatest variation and intensity of epithelial surface staining was observed with WGA and the weakest with LTA. The patchy staining with LTA compared with thick coverage by WGA indicated the complexity of the carbohydrate arrangement in the glycocalyx of the uterine surface plasma membrane. Reduction of WGA reactivity after neuraminidase treatment suggested that the lectin binding might be related to the presence of heavily sialylated apical uterine membrane glycoconjugates. This is the first high-resolution study in primates to report quantitative cyclic changes in fucosyl, galactosyl, glucosyl, and mannosyl sugar residues of the apical uterine epithelial glycocalyx. The findings support the concept that uterine epithelial glycocalyx surface carbohydrates play a role in preparing a receptive uterine surface.

Abstract
Ultrasonography was used in six saddle back tamarin females (Saguinus fuscicollis) to diagnose pregnancy, monitor the patterns of uterine growth and embryonic/foetal development and examine the incidence loss of single embryos/foetuses. Pregnancy was reliably diagnosed 17 days after conception, 10 days earlier than by plasma progesterone measurement. The patterns of uterine and embryonic/foetal growth paralleled those reported for the common marmoset, including a delay in embryonic development. The results support the hypothesis of retardation of organogenesis in most callitrichid species. Individual embryos could be reliably identified from day 50 of pregnancy; a loss of single embryos/foetuses after this stage did not occur. All pregnancies were carried to term, resulting in five times twins and one singleton. The smaller litter size compared to the common marmoset may be due to loss of single embryos at earlier stages of pregnancy or to a lower ovulation rate.

Abstract
BACKGROUND The objective was to develop an experimental model for studying the differentiation of trophoblast and inner cell mass (ICM) during the early stages of implantation in primates. METHODS Marmoset monkey blastocytes were used in these studies. Ovulation was timed by plasma progesterone assays in ovarian cycles initiated by administering a luteolytic agent to mating marmosets. Embryos were recovered from the uterus usually at the eight-cell stage and cultured in minimum essential medium containing fetal calf serum, insulin, and transferrin. The embryos that formed hatched blastocysts by about day 11 after ovulation were transferred for further development in Matrigel-coated culture chambers. After 2, 4, and 6 days of development, two blastocysts were processed at each interval and serially sectioned for light and electron microscopy. RESULTS All blastocysts adhered to the Matrigel at their embryonic pole within 24 hours. Adherent polar cytotrophoblast was differentiating to syncytiotrophoblast at all time intervals, but syncytium was not detected in mural trophoblast until day 4 after attachment. By day 2 syncytial microvilli and processes had penetrated the Matrigel surface, whereas by days 4 and 6 cytotrophoblast that was differentiating to syncytiotrophoblast had invaded the matrix. Since all blastocysts maintained their structural integrity progressive differentiation of the ICM, endoderm and presumptive mesoderm was observed. A small amniotic cavity was observed at 2 days and by 6 days a distinct cavity separated polarized epiblast and amnion cells. Visceral and parietal endoderm were present at 2 days, and a completed primary yolk sac was observed by 4 days after attachment. In all blastocysts a basal lamina lined the inner surface of mural and polar trophoblast and the basal surface of the differentiating ICM. CONCLUSIONS The developmental time sequence of the cultured blastocysts closely resembled the time frame reported for marmoset embryos implanting in utero. An effective model for studying trophoblast invasion and differentiation of embryonic germ cell layers has been established.

Abstract
We applied qualitative cytochemical procedures to investigate and compare the distribution of 3 beta-hydroxysteroid dehydrogenases (HSDH) in pro- and diestrus ovaries of sexually mature marmosets (Callithrix jacchus) using dehydroepiandrosterone or etiocholane-3 beta-ol-17-one as the substrate. During proestrus dehydroepiandrosterone dehydrogenase (3 beta-5 alpha-HSDH) activity was found in the theca of tertiary follicles and in atretic granulosa cells. In granulosa cells at advanced stages of degeneration, HSDH activity was distinctly higher than in thecal cells. The activity of etiocholane-3 beta-ol-17-one dehydrogenase (3 beta-5 beta-HSDH) exhibited a gradient in preovulatory follicles, ranging from high levels in granulosa cells adjacent to the basement membrane to low levels in cells bordering on the antrum and in cumulus oophorus cells. During diestrus 3 beta-5 alpha-HSDH activity was only detected in the corpora lutea; the level of 3 beta-5 beta-HSDH activity was unchanged in the theca of tertiary follicles and was high in the cells of the corpora lutea. HSDH activity was no longer detectable in atretic granulosa cells using either dehydroepiandrosterone or etiocholane-3 beta-ol-17-one as the substrate. Comparison of the distribution of HSDH during proestrus and diestrus revealed that steroidogenesis in marmoset ovaries occurs in follicular elements during diestrus and almost exclusively in the corpora lutea during diestrus. From this phase-dependent localization, it is possible to determine the stage of the estrous cycle. Furthermore, our findings indicate that the localization of HSDH is dependent on the conformational structure of the substrate used.

Abstract
The ultrastructural morphology of the initial stages of implantation in the marmoset monkey (Callithrix jacchus) was studied in pregnant monkeys at known time intervals after ovulation. The earliest samples, obtained 13 days after ovulation, displayed both cytotrophoblast and syncytiotrophoblast. The cytotrophoblast was restricted to the blastocoel, whilst syncytiotrophoblast intruded to the endometrial basal lamina. At later stages, days 16 and 19 after ovulation, both cytotrophoblast and syncytiotrophoblast had extended laterally around the uterus, and the syncytiotrophoblast also extended deeper into the maternal tissues. The mesoderm layer was first discernible at 19 days after ovulation. At 23 days after ovulation the syncytiotrophoblast surrounded the maternal blood vessels entirely. In this study syncytiotrophoblast was not observed to breach the maternal blood vessels, even at 31 days after ovulation. Early cytotrophoblast columns could be seen at 31 days after ovulation. The endothelial cells lining the maternal blood vessels displayed hypertrophy from the earliest stages (day 13) onwards, although a true decidual response was only observed in samples of 23 and 31 days after ovulation.

Abstract
The morphology of the initial stages of implantation in the marmoset monkey (Callithrix jacchus) was studied by obtaining embryos and associated endometrium at timed intervals after ovulation. Estrus cycles were detected by measuring daily levels of plasma progesterone. Following a short follicular phase, circulating levels of progesterone above 20 ng/ml were taken as representing day 1 after ovulation. On this basis, single, twin, and triplet embryos were recovered from six perfused-fixed females on days 13, 16, 19, 23, and 29 after ovulation and prepared in resin for light microscopy. Early implantation stages, 13 and 16 days after ovulation, were characterized by the intrusion of syncytial trophoblast between epithelial cells of the endometrium with minimal cellular damage. Some hyperplasia of epithelium at the margin of the implantation site was evident. The consolidation of the initial attachment was achieved by an increase in syncytial trophoblast underlying the inner cell mass of the embryo which rapidly surrounded and breached maternal capillaries. Although initially separate, the chorions of twin or triplet embryos started to fuse by day 19 after ovulation. This process was complete by day 29 such that embryos shared a common uterine exocoelom surrounded by continuous trophoblast. It was concluded that implantation in the marmoset monkey commenced on days 11-12.5 after ovulation and involved an intrusive mechanism. Although trophoblast penetration of endometrium was superficial, maternal capillaries were tapped at an early stage of implantation. The fusion of chorions of twins and triplets first occurred around day 19 after ovulation.
