Abstract
During implantation, a symphony of interaction between the trophoblast originated from the trophectoderm of the implanting blastocyst and the endometrium leads to a successful pregnancy. Defective interaction between the trophoblast and endometrium often results in implantation failure, pregnancy loss, and a number of pregnancy complications. Owing to ethical concerns of using in vivo approaches to study human embryo implantation, various in vitro culture models of endometrium were established in the past decade ranging from two-dimensional cell-based to three-dimensional extracellular matrix (ECM)/tissue-based culture systems. Advanced organoid systems have also been established for recapitulation of different cellular components of the maternal-fetal interface, including the endometrial glandular organoids, trophoblast organoids and blastoids. However, there is no single ideal model to study the whole implantation process leaving more research to be done pursuing the establishment of a comprehensive in vitro model that can recapitulate the biology of trophoblast-endometrium interaction during early pregnancy. This would allow us to have better understanding of the physiological and pathological process of trophoblast-endometrium interaction during implantation.

Abstract
BACKGROUND A novel organotypic culture system was established for modelling the hormonal responses of the normal human endometrium in vitro. METHODS Endometrial epithelial cells were cultured as glandular organoids within reconstituted extracellular matrix (Matrigel) in tissue culture inserts and stromal cells on plastic below the epithelial compartment. The effects of estradiol (E2) and E2 together with medroxyprogesterone acetate (MPA) on cell proliferation and the expression of estrogen receptor alpha (ERalpha) and progesterone receptor (PR) were studied in 10 epithelial-stromal co-cultures and in three parallel monocultures of epithelial organoids. RESULTS In co-cultures, E2 was shown to increase the percentage of Ki67-positive cells by approximately 2-fold relative to untreated controls. In the presence of MPA, a significant decrease in cell proliferation was detected. Similar results were obtained when the corresponding percentages of Ki67-positive organoids were calculated instead of individual cells. In the absence of stromal fibroblasts, Ki67 epithelial labelling remained below the control value after both hormonal treatments. Epithelial organoids retained their capacity to express estrogen and progesterone receptors in culture. E2 was shown to markedly increase and MPA to down-regulate the expression of PR. The expression of ERalpha was only slightly affected by either hormonal treatment. CONCLUSIONS The present organotypic model provides a novel in vitro system in which to study the effects of steroids in the normal human endometrium both in terms of cell proliferation and gene expression. The culture system holds promise as a useful method to screen novel steroid compounds and may help to circumvent problems related to the use of animal models.

Abstract
The regulation of epithelial cell function and morphogenesis by the paracrine effectors from the mesenchyme or stroma has been well established using in-vivo studies. A more complete understanding of these relationships has been delayed due, in part, to a lack of appropriate co-culture models. In this study, we describe a co-culture model which demonstrates that normal paracrine relationships can be reconstituted in vitro and that human endometrial stromal cells regulate both growth and differentiation of primary human endometrial epithelial cells. Interesting differences in the proliferation of stromal and epithelial cells were noted in response to the basement membrane extract, Matrigel((R)). Exposure of stromal cells to Matrigel((R)) enhanced the paracrine capacity of these cells in vitro. When epithelial cells were co-cultured in contact with stromal cells embedded in Matrigel((R)), epithelial cell growth was inhibited by 65-80% compared to controls. Stromal cells in contact with Matrigel((R)) also regulated epithelial cell differentiation, as shown by induction of glycodelin expression. These co-culture studies show great promise as a method to investigate the cellular interactions between endometrial stromal and epithelial cells and their environment and to understand the molecular basis for the regulation of normal growth and differentiation of cells within complex tissues such as the endometrium.

Abstract
This paper reviews different in vitro models used for the study of blastocyst implantation in animals and the human. Furthermore, results from human blastocyst-endometrial interactions in vitro, investigated by scanning electron microscopy (SEM), light microscopy (LM) and transmission electron microscopy (TEM), are presented. SEM demonstrates the preference of human blastocysts to adhere to pinopode-presenting areas on endometrial cell cultures. LM and TEM show that the first morphological sign of cell contact, defined as junction formation, is present at the apical-to-lateral border of endometrial epithelial cells, whereas trophoblast attachment to apical endometrial epithelial plasma membranes was not observed. More advanced stages illustrate that the human blastocyst penetrates the epithelial lining by the intrusive penetration mechanism.

Abstract
Human epithelial cells of the Ishikawa endometrial line can be stimulated to differentiate and form multicellular structures in 4-5 day-old monolayer cultures by the addition of a protein factor from fetal bovine serum. Multicellular structures become obvious over an 18-30-h period as the cells enlarge, separate from the dish, and form domes. These structures are similar to those that result from polarization in other epithelial cell lines. Ishikawa dome formation appears to be a multistage process. The appearance of enlarged differentiated cells is detected within hours of adding fetal bovine serum; these enlarged cells lift off the surface of the dish within 6-8 more hours. Domes are observed about 24 h after the addition of fetal bovine serum. Sometimes dome cells migrate into a "bud-like" structure that extends out from the dome. Differentiation of the domes is dependent on a factor from fetal calf serum that behaves similarly to a very large protein or complex of proteins, greater than 300 kd. Progesterone appears to enhance the formation of domes but does not elicit dome formation in the absence of serum factor.

Abstract
We have developed a system for serum-free culture of separated uterine epithelium and stroma from 11-day-old rats recombined on extracellular matrix extracted from Englebreth-Holm-Swarm tumors. Epithelium grew and, after 2 days in culture, developed into luminal epithelial spheres (LES) surrounding a fluid-filled lumen. Individual LES cells maintained epithelial cell characteristics such as basally located nuclei, apical microvilli (oriented toward the lumen), lateral membranes with interdigitations and desmosomes, secretory Golgi complexes, and abundant mitochondria and rough endoplasmic reticulum. Secretory vesicles were ubiquitous throughout the luminal fluid. Addition of 17 beta-estradiol to the growth medium increased the number and longevity of the LES. Prior exposure of uteri to tamoxifen via s.c. injection in vivo on postnatal Days 1 to 5 reduced or completely inhibited formation of LES in vitro. These effects occurred regardless of whether the stromal or epithelial component of the recombinant tissue was exposed to tamoxifen. These data suggest a directive property of neonatal stroma in culture resulting in the formation of highly secretory spherical epithelial structures completely enclosing a lumen. LES formation is responsive to both estrogen (positive response) and antiestrogen (negative response).

Abstract
Culture of the human neoplastic submandibular gland intercalated duct cell line, HSG, on the basement membrane extract Matrigel induces dramatic morphologic changes and cytodifferentiation. Transmission electron microscopy demonstrated an acinar cell phenotype with polarized cells containing a well-developed Golgi apparatus, multiple microvilli-like projections from the apical surfaces into a lumenal-like area, and numerous granule-like organelles. Amylase, an acinar cell marker, was detected by both immunocytochemical and Northern blot analyses. A 50% reduction in [3H]thymidine incorporation by cells cultured on Matrigel, as compared to cells cultured on tissue culture plates, confirmed the differentiated phenotype of the cells. Multiple components of Matrigel appear to contribute to the morphologic differentiation of the HSG cells since antibodies to both laminin and collagen IV, as well as the laminin-derived bioactive peptide containing SIKVAV, have potent inhibitory effects on HSG cell organization on Matrigel. Collectively, these data indicate that culture of HSG cells on Matrigel is a useful model to study salivary gland acinar development.

Abstract
Implantation is the process that leads from blastocyst attachment to its embedding in the uterine wall. It is widely believed that failure of implantation is a common cause of pregnancy loss. Toxic agents can interfere directly with the process of implantation and therefore may account for unexplained implantation failures. Our knowledge of human implantation remains limited, mainly due to the lack of adequate experimental models. Studies of mechanisms underlying implantation in humans are by nature and for ethical reasons restricted to in vitro models. The aim of this review is to provide a critical evaluation of various in vitro models of implantation in humans, as well as essential background knowledge required for application of these models to the assessment of peri-implantation toxicity. Particular attention has been devoted to cell-cell and cell-matrix interactions as possible endpoints in the screening of toxic agents.

Abstract
OBJECTIVE To evaluate the proliferative and morphogenic effects induced by the coculture of uterine and peritoneal cells to establish a cell culture model for endometriosis. DESIGN Uterine epithelial and stromal cells and peritoneal mesothelial and subserosal cells were cocultured with homologous cell types, heterologous cell types, or as isolated populations using a bicameral chamber design. SETTING Department of Obstetrics and Gynecology at the University of Missouri, Columbia, Missouri. ANIMALS Cells isolated and purified from five mature female Sprague Dawley rats of normal reproductive status were used to establish cell cultures. MAIN OUTCOME MEASURES Cell proliferation (deoxyribonucleic acid synthesis) was measured by the incorporation of 3H-thymidine, and cell morphology was assessed using inverted phase-contrast microscopy. RESULTS Peritoneal mesothelial cells augmented proliferation and induced cellular aggregation of uterine stromal cell monolayers. Peritoneal subserosal cells amplified proliferation and induced an irregular, compacted morphology in uterine epithelial cells. The proliferation and morphology of the two peritoneal cell types was not altered by uterine cell coculture. CONCLUSIONS The coculture of uterine and peritoneal cells in bicameral chambers provides a tool to study the paracrine interactions of cells that comprise the endometriotic lesion. The altered proliferation and morphology of the uterine cells may be related to the histologic and biochemical asynchrony observed between uterine endometrium and ectopic endometriotic tissue in vivo and offers insight into possible mechanisms of the histogenesis of endometriosis.

Abstract
Normal human breast epithelial cells show a high degree of phenotypic plasticity in monolayer culture and express many traits that otherwise characterize tumor cells in vivo. Paradoxically, primary human breast carcinoma cells are difficult to establish in culture: most outgrowths arise from the normal tissue surrounding the tumor. These characteristics have posed major obstacles to the establishment of simple reliable criteria for mammary epithelial transformation in culture. In the present study, we show that a reconstituted basement membrane (BM) can be used to culture all normal human breast epithelial cells and a subset of human breast carcinoma cells. The two cell types can be readily distinguished by virtue of the ability of normal cells to reexpress a structurally and functionally differentiated phenotype within BM. Twelve specimens of normal breast tissue and 2 normal breast epithelial cell lines (total 14 samples) embedded in BM as single cells were able to form multicellular spherical colonies with a final size close to that of true acini in situ. Sections of mature spheres revealed a central lumen surrounded by polarized luminal epithelial cells expressing keratins 18 and 19 and sialomucin at the apical membrane. Significantly, two-thirds of normal spheres deposited a visible endogenous type IV collagen-containing BM even though they were in contact with exogenously provided BM. Growth was arrested completely within the same time period. In contrast, none of 6 carcinoma cell lines or 2 cultures of carcinoma from fresh samples (total 8 samples) responded to BM by growth regulation, lumen formation, correct polarity, or deposition of endogenous BM. These findings may provide the basis of a rapid assay for discriminating normal human breast epithelial cells from their malignant counterparts. Furthermore, we propose that the ability to sense BM appropriately and to form three-dimensional organotypic structures may be the function of a class of "suppressor" genes that are lost as cells become malignant.

Abstract
We have studied the interaction of a human tumor cell line, A253, derived from a submandibular gland carcinoma with a differentiation promoting reconstituted basement membrane extract, Matrigel. When cultured on plastic, these cells maintain a flat, cobblestone, epithelial morphology. On Matrigel, A253 cells initially form a honeycomb network of cords of cells which subsequently thickens. With time, these cords of cells become discontinuous and blunted, whereupon multilobular clusters of cells develop. These clusters possess a lumen with polarized, PAS(+) cells containing numerous desmosomes and an abundance of glycogen. Culture of the cells on laminin, the most abundant protein found in Matrigel, also induces this morphologic differentiation. Using synthetic laminin-derived peptides, the biologically active IKVAV-containing site of laminin was most active in attachment assays, as well as in inhibiting glandular-like morphogenesis when added to the media of cells cultured on Matrigel. Antibodies to the cell surface 67- and 32-kDa laminin binding proteins partially inhibited the glandular-like morphogenesis, suggesting that multiple interactions with laminin are likely required for the differentiation process. Our data demonstrate that A253 cells can undergo glandular-like morphogenesis on basement membrane and that laminin appears to be the major initiating factor.

Abstract
A quantitative assay for morphogenesis is described that involves counting the organizing centers (swirling patterns) formed by many cultured fibroblasts. Organizing centers, which are found in vivo, represent one of the smallest units of morphogenesis. We show that macroscopically visible organizing centers form by the merger of smaller organizing centers. Parallel orientation of cells on plastic substrata requires cell-cell contact, but organizing centers can develop without cell-cell contact on collagen gels. On collagen gels, the orientation of collagen fibers determines the orientation of cells with respect to one another. Although organizing centers resemble fingerprints, we have shown that a stochastic process determines the spatial orientation of organizing centers. Treatment of transformed cell lines with agents that increase cAMP levels or alter the activity of guanine nucleotide binding proteins resulted in the generation of organizing centers. Cholesterol precursors involved in protein isoprenylation were found to be potent reverse-transformation agents that could alter the two-dimensional morphogenesis of cells. The simple assay described should permit the analysis of morphogenesis at the molecular and cellular levels.
