Detection of Carcinoma-Associated Fibroblasts Derived from Mesothelial Cells via Mesothelial-to-Mesenchymal Transition in Primary Ovarian Carcinomas. Cancers (Basel) 2024; 16:2697. [PMID: 39123425 PMCID: PMC11311419 DOI: 10.3390/cancers16152697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2024] [Revised: 07/23/2024] [Accepted: 07/27/2024] [Indexed: 08/12/2024] Open
Abstract
Carcinoma-associated fibroblasts (CAFs) are highly accumulated in the tumor-surrounding stroma of primary epithelial ovarian cancer (OC). CAFs exert important functions for the vascularization, growth, and progression of OC cells. However, the origin of CAFs in primary OC had not yet been studied, and they were assumed to arise from the activation of resident fibroblasts. Here, we compared CAFs in the ovary to CAFs found in peritoneal metastases from patients with advanced OC. Our findings show that CAFs from primary tumors and peritoneal metastases share the expression of mesothelial markers. Therefore, similar to peritoneal carcinomatosis, CAFs in primary ovarian carcinomas may originate from mesothelial cells via a mesothelial-to-mesenchymal transition. The detection of mesothelial-derived CAFs in tumors confined to the ovary and identification of biomarkers could be the key to the early detection of OC and peritoneal spread.

Intraoperative Appearance of Endosalpingiosis: A Single-Center Experience of Laparoscopic Findings and Systematic Review of Literature. J Clin Med 2022; 11:jcm11237006. [PMID: 36498581 PMCID: PMC9738105 DOI: 10.3390/jcm11237006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 11/21/2022] [Accepted: 11/23/2022] [Indexed: 11/29/2022] Open
Abstract
Background: Endosalpingiosis is assumed to be the second most common benign peritoneal pathology after endometriosis in women. Although recent studies indicate a significant association with gynecologic malignancies, many underlying principles remain unclear. This work aimed to systematically describe the intraoperative appearance of endosalpingiosis. Methods: Data and intraoperative videos of patients with histologically verified endosalpingiosis were retrospectively reviewed. The main outcome measures were macroscopic phenotype and anatomical distribution. Additionally, a systematic review searching PubMed (Medline) and Embase was conducted. Results: In the study population (n = 77, mean age 40.2 years (SD 16.4)), the mean size of lesions was 3.6 mm and the main visual pattern was vesicular (62%). The most frequent localization was the sacrouterine ligaments (24.7%). In the systematic review population (n = 1174 (210 included studies overall), mean age 45.7 years (SD 14.4)), there were 99 patients in 90 different studies with adequate data to assess the appearance of the lesions. The mean size of the lesions was 48.5 mm, mainly with a cystic visual pattern (49.5%). The majority of the lesions affected the ovaries (23.2%), fallopian tubes (20.4%), or lymph nodes (18.5%). Comparing this study to the literature population, the main differences concerned the size (p < 0.001) and main visual patterns (p < 0.001) of lesions. Conclusions: The usual intraoperative findings of endosalpingiosis appeared less impressive than described in the literature. In our study population, lesions of a few millimeters in size with a vesicular appearance were mostly seen, most frequently in the sacrouterine ligament area. Intraoperative recognition by the gynecologic surgeon and histologic diagnosis should play an important role in further understanding this entity, scientifically and clinically.

Abstract
Wnt5A and receptor tyrosine kinase-like orphan receptor 2 (ROR2) proteins both regulate developmental processes, cell movement, and cell polarity. The purpose of this study was to evaluate a possible regulatory role of Wnt5A on ROR2 expression in human ovarian cancer cell lines. Moreover, the expression of Wnt5A and ROR2 mRNA and protein levels were assessed in human epithelial serous ovarian cancer (HSOC) specimens. ROR2 was strongly decreased in cells treated with siRNA against Wnt5A compared with scramble-treated or lipofectamine-treated cells (P < 0.001). There was 34% decreased cell invasion (P < 0.01) in Wnt5A knock-down cells compared with lipofectamine-treated and scramble-treated cells; however, cell invasion remained unchanged upon addition of anti-ROR2 antibody to the culture media of these cells. In contrast, addition of anti-ROR2 antibody to the culture media for lipofectamine-treated and scramble-treated cells led to 32% decreased cell invasion (P < 0.01). Normal ovarian specimens were negative, and variable immunostaining was observed in HSOC for Wnt5A and ROR2 immunostaining. Furthermore, there was a positive correlation between Wnt5A and ROR2 expression in high-grade SOC samples at the mRNA level (P < 0.05; r = 0.38). This is the first report to show the regulatory role of Wnt5A on ROR2 expression in ovarian cancer.

Abstract
Background: Alpha-smooth muscle actin (α-SMA) is an isoform of actin, positive in myofibroblasts and is an epithelial to mesenchymal transition (EMT) marker. EMT is a process by which tumor cells develop to be more hostile and able to metastasize. Progression of tumor cells is always followed by cell composition and extracellular matrix component alteration. Increased α-SMA expression and collagen alteration may predict the progressivity of ovarian neoplasms. Objective: The aim of this research was to analyse the characteristic of α-SMA and collagen in tumor cells and stroma of ovarian neoplasms. In this study, PCNA (proliferating cell nuclear antigen) expression was also investigated. Methods: Thirty samples were collected including serous, mucinous, endometrioid, and clear cell subtypes. The expression of α-SMA and PCNA were calculated in cells and stroma of ovarian tumors. Collagen was detected using Sirius Red staining and presented as area fraction. Results: The overexpressions of α-SMA in tumor cells were only detected in serous and clear cell ovarian carcinoma. The histoscore of α-SMA was higher in malignant than in benign or borderline ovarian epithelial neoplasms (105.3±129.9 vs. 17.3±17.1, P=0.011; mean±SD). Oppositely, stromal α-SMA and collagen area fractions were higher in benign than in malignant tumors (27.2±6.6 vs 20.5±8.4, P=0.028; 31.0±5.6 vs. 23.7±6.4, P=0.04). The percentages of epithelial and stromal PCNA expressions were not significantly different between benign and malignant tumors. Conclusion: Tumor cells of serous and clear cell ovarian carcinoma exhibit mesenchymal characteristic as shown by α-SMA positive expression. This expression might indicate that these subtypes were more aggressive. This research showed that collagen and α-SMA area fractions in stroma were higher in benign than in malignant neoplasms.

Abstract
Epithelial ovarian cancer (EOC) dissemination is primarily mediated by the shedding of tumor cells from the primary site into ascites where they form multicellular spheroids that rapidly lead to peritoneal carcinomatosis. While the clinical importance and fundamental role of multicellular spheroids in EOC is increasingly appreciated, the mechanisms that regulate their formation and dictate their cellular composition remain poorly characterized. To investigate these important questions, we characterized spheroids isolated from ascites of women with EOC. We found that in these spheroids, a core of mesothelial cells was encased in a shell of tumor cells. Analysis further revealed that EOC spheroids are dynamic structures of proliferating, non-proliferating and hypoxic regions. To recapitulate these in vivo findings, we developed a three-dimensional co-culture model of primary EOC and mesothelial cells. Our analysis indicated that, compared to the OVCAR3 cell line, primary EOC cells isolated from ascites as well as mesothelial cells formed compact spheroids. Analysis of heterotypic spheroid microarchitecture revealed a structure that grossly resembles the structure of spheroids isolated from ascites. Cells that formed compact spheroids had elevated expression of β1 integrin and low expression of E-cadherin. Addition of β1 integrin blocking antibody or siRNA-mediated downregulation of β1 integrin resulted in reduced tightness of the spheroids. Interestingly, the loss of MUC16 and E-cadherin expression resulted in the formation of more compact spheroids. Therefore, our findings support the heterotypic nature of spheroids from malignant EOC ascites. In addition, our data describe an unusual link between E-cadherin expression and less compact spheroids. Our data also emphasize the role of MUC16 and β1 integrin in EOC spheroid formation.

Abstract
The peritoneal metastatic route of cancer dissemination is shared by cancers of the ovary and gastrointestinal tract. Once initiated, peritoneal metastasis typically proceeds rapidly in a feed-forward manner. Several factors contribute to this efficient progression. In peritoneal metastasis, cancer cells exfoliate into the peritoneal fluid and spread locally, transported by peritoneal fluid. Inflammatory cytokines released by tumor and immune cells compromise the protective, anti-adhesive mesothelial cell layer that lines the peritoneal cavity, exposing the underlying extracellular matrix to which cancer cells readily attach. The peritoneum is further rendered receptive to metastatic implantation and growth by myofibroblastic cell behaviors also stimulated by inflammatory cytokines. Individual cancer cells suspended in peritoneal fluid can aggregate to form multicellular spheroids. This cellular arrangement imparts resistance to anoikis, apoptosis, and chemotherapeutics. Emerging evidence indicates that compact spheroid formation is preferentially accomplished by cancer cells with high invasive capacity and contractile behaviors. This review focuses on the pathological alterations to the peritoneum and the properties of cancer cells that in combination drive peritoneal metastasis.

Abstract
AIMS To determine whether or not the glomeruloid implants (GI) composed of papillary cores within clear spaces lined by mesothelial cells or tumour cells located in superficial or deep peritoneal tissue in ovarian serous borderline tumours (SBTs) are invasive. METHODS AND RESULTS We examined the differences in incidence, histological and immunohistochemical findings among three groups: 100 GI with mesothelial cells lining clear space (type I), 100 GI with tumour cells lining clear space (type II), and 100 invasive implants with clefts but no lining cells from 30 cases of SBT with peritoneal implants. The type I lesion had characteristics of non-invasive implants with a tendency for smooth contours (100/100), superficial location (71/100), absence of desmoplasia (100/100) and absence of surrounding destructive invasion (100/100), In contrast, type II GI had irregular contours (67/100), deep location (93/100), presence of desmoplastic reaction (100/100) and presence of destructive invasion (12/100). Immunohistological studies suggested intermediate forms between the two types of lesions. CONCLUSIONS Type I GI are non-invasive implants, whereas type II GI are invasive implants and it is important to evaluate the presence and nature of cells lining the clear space in determining whether implants associated with ovarian SBTs are invasive or not.

Abstract
The utility of calretinin was first described in the diagnosis of mesothelioma. In the female genital tract, calretinin was initially reported in Wolffian remnants and related lesions and later used in the diagnosis of sex cord stromal tumors of the ovary, endometrial stromal tumors with sex cord-like differentiation, and uterine tumors resembling sex cord tumors of the ovary. This review discusses calretinin expression in normal tissues of the female genital tract and highlights its potential utility in the diagnosis of these subsets of neoplasms with emphasis to tumors that may constitute a problem in their differential diagnosis. In particular, the limited utility of calretinin in the diagnosis of sex cord stromal tumors of the ovary, in the differential diagnosis between mesothelioma and serous tumors involving the ovary and/or peritoneum, and in the differential diagnosis between Wolffian lesions and endometrial carcinoma are addressed.

Abstract
AIMS To determine whether elastin stains aid in classifying peritoneal implants associated with ovarian serous borderline tumours (SBT). METHODS AND RESULTS The study group comprised 80 implants (nine invasive and 71 non-invasive) from 28 patients with ovarian SBT. Elastin stains were performed using histochemical and immunohistochemical methods to demonstrate the peritoneal elastic lamina (PEL), and evaluated with regard to assessment of the subtype of implant. The elastin stains demonstrated the PEL in most anatomical sites other than the omentum and the bladder and were considered helpful in 44/80 (55%) cases. The stains were most useful in the assessment of poorly oriented or traumatized biopsy specimens and in confirming the superficial distribution of non-invasive implants. The staining was non-contributory in most of the remaining biopsies, because the PEL was not identified. CONCLUSIONS Demonstration of the PEL using elastin stains can be useful in the subclassification of implants associated with ovarian SBT and is of most value in confirming the superficial distribution of non-invasive lesions. However, evaluation is limited by the absence of a defined elastic layer in a proportion of biopsy specimens, possibly reflecting their superficial location, as well as absence of a distinct PEL in sites such as the omentum.

Abstract
Endothelial progenitor cells from the pulp of milk teeth were isolated for use in clinical applications and tissue engineering. Normal deciduous teeth from children of 7 to 8 years of age, which more than half the tooth root was extracted, were selected from the dental centre. Cells from enzyme treated pulps were cultured and cells resulting from the fifth and eight subculture were combined for cell surface marker determination experiments. Cells were positive for CD34 marker with a total of 99/45%, determined by flowcytometry. Cells also demonstrated alkaline phosphatase (ALP) activity. From the developmental point of view, stem cells from the dental pulp seem to have derived from the neural crest, which our findings technically support this theory. In essence mobile progenitor cells from bone marrow of endothelial origin could also play a significant role in the derivation of dental pulp stem cells.
