Ibrahim AS, El-Shinawi M, Sabet S, Ibrahim SA, Mohamed MM. Role of adipose tissue-derived cytokines in the progression of inflammatory breast cancer in patients with obesity. Lipids Health Dis 2022; 21:67. [PMID: 35927653 PMCID: PMC9351154 DOI: 10.1186/s12944-022-01678-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2022] [Accepted: 07/13/2022] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Inflammatory breast cancer (IBC) represents a deadly aggressive phenotype of breast cancer (BC) with a unique clinicopathological presentation and low survival rate. In fact, obesity represents an important risk factor for BC. Although several studies have identified different cellular-derived and molecular factors involved in IBC progression, the role of adipocytes remains unclear. Cancer-associated adipose tissue (CAAT) expresses a variety of adipokines, which contribute to tumorigenesis and the regulation of cancer stem cell (CSC). This research investigated the potential effect of the secretome of CAAT explants from patients with BC on the progression and metastasis of the disease. METHODS This study established an ex-vivo culture of CAAT excised from IBC (n = 13) vs. non-IBC (n = 31) patients with obesity and profiled their secretome using a cytokine antibody array. Furthermore, the quantitative PCR (qPCR) methodology was used to validate the levels of predominant cytokines at the transcript level after culture in a medium conditioned by CAAT. Moreover, the impact of the CAAT secretome on the expression of epithelial-mesenchymal transition (EMT) and cells with stem cell (CSC) markers was studied in the non-IBC MDA-MB-231 and the IBC SUM-149 cell lines. The statistical differences between variables were evaluated using the chi-squared test and unpaired a Student's t-test. RESULTS The results of cytokine array profiling revealed an overall significantly higher level of a panel of 28 cytokines secreted by the CAAT ex-vivo culture from IBC patients with obesity compared to those with non-IBC. Of note, interleukin-6 (IL-6), interleukin-8 (IL-8), and monocyte chemo-attractant protein 1 (MCP-1) were the major adipokines secreted by the CAAT IBC patients with obesity. Moreover, the qPCR results indicated a significant upregulation of the IL-6, IL-8, and MCP-1 mRNAs in CAAT ex-vivo culture of patients with IBC vs. those with non-IBC. Intriguingly, a qPCR data analysis showed that the CAAT secretome secretions from patients with non-IBC downregulated the mRNA levels of the CD24 CSC marker and of the epithelial marker E-cadherin in the non-IBC cell line. By contrast, E-cadherin was upregulated in the SUM-149 cell. CONCLUSIONS This study identified the overexpression of IL-6, IL-8, and MCP-1 as prognostic markers of CAAT from patients with IBC but not from those with non-IBC ; moreover, their upregulation might be associated with IBC aggressiveness via the regulation of CSC and EMT markers. This study proposed that targeting IL-6, IL-8, and MCP-1 may represent a therapeutic option that should be considered in the treatment of patients with IBC.

de Almeida MHR, Bortolotto GDS, Dutra RC, Guimarães GN, Felipetti FA. Cell culture of the normal human mammary gland cultivated in monolayer - A mini systematic review. Acta Histochem 2021; 123:151798. [PMID: 34666236 DOI: 10.1016/j.acthis.2021.151798] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 10/07/2021] [Accepted: 10/08/2021] [Indexed: 11/29/2022]
Abstract
The mammary glands are constituted of different cell types. For example, the epithelial cells appear as the target in many studies since they produce and secrete milk during lactation and are the origin of many human breast cancers. Mammary gland biology is characterized by dynamic tissue growth, function and regression phases, which are understood mainly due to tissue culture studies. Cell culture is probably one of the most used in vitro scientific models, and the most common research model is still the two-dimensional (2D) culture system. Different approaches and conditions have been tested and used to improve the isolation, growth, yield and maintenance of viability of mammary gland cells. Therefore, our study aimed to explore and summarize the cell culture techniques with normal human mammary gland cells cultured in a monolayer. A search strategy was conducted using the electronic databases 'PubMed', 'Scopus' and 'Virtual Health Library'. The search was carried out using the keywords 'cell culture' and 'mammary gland' and 'human'. The main search was carried out by two authors between July and August 2021. In addition, we performed a review matrix elaborated in a spreadsheet to organize and systematize information about each article for inclusion. A total of 11 studies were included in the review and have conducted qualitative analyses on them. Although studies of these cells have been reported since the 1970 s, most found are from the last decade and are largely carried out in the USA. In addition, it was possible to verify the Human Mammary Epithelial Cells (HMEC) primary culture obtained from breast surgery as the main cell type studied. These cells are cultivated in Dulbecco's Modified Eagle Medium (DMEM) and M87A medium with diverse supplements. Finally, there was a diversity in the use of dissociation reagents and a lack of information about cryopreservation. We have observed detailed methodological information about these study models, which would propose further investigations.

Abstract
Current gold standard to treat soft tissue injuries caused by trauma and pathological condition are autografts and off the shelf fillers, but they have inherent weaknesses like donor site morbidity, immuno-compatibility and graft failure. To overcome these limitations, tissue-engineered polymers are seeded with stem cells to improve the potential to restore tissue function. However, their interaction with native tissue is poorly understood so far. To study these interactions and improve outcomes, we have fabricated scaffolds from natural polymers (collagen, fibrin and elastin) by custom-designed processes and their material properties such as surface morphology, swelling, wettability and chemical cross-linking ability were characterised. By using 3D scaffolds, we comprehensive assessed survival, proliferation and phenotype of adipose-derived stem cells in vitro. In vivo, scaffolds were seeded with adipose-derived stem cells and implanted in a rodent model, with X-ray microtomography, histology and immunohistochemistry as read-outs. Collagen-based materials showed higher cell adhesion and proliferation in vitro as well as higher adipogenic properties in vivo. In contrast, fibrin demonstrated poor cellular and adipogenesis properties but higher angiogenesis. Elastin formed the most porous scaffold, with cells displaying a non-aggregated morphology in vitro while in vivo elastin was the most degraded scaffold. These findings of how polymers present in the natural polymers mimicking ECM and seeded with stem cells affect adipogenesis in vitro and in vivo can open avenues to design 3D grafts for soft tissue repair.

Laterality and Patient-Reported Outcomes following Autologous Breast Reconstruction with Free Abdominal Tissue: An 8-Year Examination of BREAST-Q Data. Plast Reconstr Surg 2020; 146:964-975. [PMID: 33141527 DOI: 10.1097/prs.0000000000007239] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/21/2022]
Abstract
BACKGROUND Despite the rise in rates of contralateral prophylactic mastectomy, few studies have used patient-reported outcomes to assess satisfaction between unilateral and bilateral breast reconstruction with autologous tissue. The purpose of this study was to investigate patient satisfaction and quality of life following autologous reconstruction to determine whether differences exist between unilateral and bilateral reconstructions to better guide clinical decision-making. METHODS The current study examined prospectively collected BREAST-Q results following abdominal free flap breast reconstruction procedures performed at a tertiary academic medical center from 2009 to 2017. The reconstruction module of the BREAST-Q was used to assess outcomes between laterality groups (unilateral versus bilateral) at 1 year, 2 years, 3 years, and more than 3 years. RESULTS Overall, 405 patients who underwent autologous breast reconstruction completed the BREAST-Q. Cross-sectional analysis at 1 year, 2 years, and 3 years revealed similar satisfaction scores between groups; however, bilateral reconstruction patients demonstrated higher satisfaction scores at more than 3 years (p = 0.04). Bilateral reconstruction patients reported lower scores of abdominal well-being at 1 year, 2 years, and more than 3 years (p = 0.01, p = 0.03, and p = 0.01, respectively). CONCLUSIONS These results suggest that satisfaction with breasts does not differ with the laterality of the autologous reconstruction up to 3 years postoperatively but may diverge thereafter. Bilateral reconstruction patients, however, have lower satisfaction with the abdominal donor site. These data can be used in preoperative counseling, informed consent, and expectations management in patients considering contralateral prophylactic mastectomy.

Abstract
The complexity of mammary tissue and the variety of cells involved make tissue regeneration an ambitious goal. This review, supported by both detailed macro and micro anatomy, illustrates the potential of regenerative medicine in terms of mammary gland reconstruction to restore breast physiology and morphology, damaged by mastectomy. Despite the widespread use of conventional therapies, many critical issues have been solved using the potential of stem cells resident in adipose tissue, leading to commercial products. in vitro research has reported that adipose stem cells are the principal cellular source for reconstructing adipose tissue, ductal epithelium, and nipple structures. In addition to simple cell injection, construct made by cells seeded on a suitable biodegradable scaffold is a viable alternative from a long‐term perspective. Preclinical studies on mice and clinical studies, most of which have reached Phase II, are essential in the commercialization of cellular therapy products. Recent studies have revealed that the enrichment of fat grafting with stromal vascular fraction cells is a viable alternative to breast reconstruction. Although in the future, organ‐on‐a‐chip can be envisioned, for the moment researchers are still focusing on therapies that are a long way from regenerating the whole organ, but which nevertheless prevent complications, such as relapse and loss in terms of morphology.

Abstract
Objectives: The authors seek to highlight some of the ongoing challenges related to complex oncologic reconstruction and the current solutions to these problems. Summary: The standard of care in reconstruction following oncologic resection is continually evolving. Current frontiers in breast reconstruction include addressing animation deformity through prepectoral reconstruction, offering autologous reconstruction to patients with limited donor sites, and improving postoperative sensation with innervation of free tissue transfer. Facial nerve reconstruction and contour defects pose an ongoing challenge in patients undergoing parotidectomy requiring complex nerve transfers and autologous reconstruction. Lymphedema is not a monolithic disease, and as our understanding of the pathophysiology improves, our surgical algorithms continue to evolve.

Abstract
The most common malignancy in women, breast cancer remains a major medical challenge that affects the life of thousands of patients every year. With recognized benefits to body image and self-esteem, the use of synthetic mammary implants for elective cosmetic augmentation and post-mastectomy reconstruction continues to increase. Higher breast implant use leads to an increased occurrence of implant-related complications associated with implant leakage and rupture, capsular contracture, necrosis and infections, which include delayed healing, pain, poor aesthetic outcomes and the need for revision surgeries. Along with the health status of the implant recipient and the skill of the surgeon, the properties of the implant determine the likelihood of implant-related complications and, in doing so, specific patient outcomes. This paper will review the challenges associated with the use of silicone, saline and "gummy bear" implants in view of their application in patients recovering from breast cancer-related mastectomy, and investigate the opportunities presented by advanced functional nanomaterials in meeting these challenges and potentially opening new dimensions for breast reconstruction. STATEMENT OF SIGNIFICANCE: Breast cancer is a significant cause of morbidity and mortality in women worldwide, which is difficult to prevent or predict, and its treatment carries long-term physiological and psychological consequences. Post-mastectomy breast reconstruction addresses the cosmetic aspect of cancer treatment. Yet, drawbacks of current implants contribute to the development of implant-associated complications, which may lead to prolonged patient care, pain and loss of function. Nanomaterials can help resolve the intrinsic biomechanical mismatch between implant and tissues, enhance mechanical properties of soft implantable materials, and provide an alternative avenue for controlled drug delivery. Here, we explore advances in the use of functionalized nanomaterials to enhance the properties of breast implants, with representative examples that highlight the utility of nanomaterials in addressing key challenges associated with breast reconstruction.

Abstract
Retinoic acid-induced protein 3 (RAI3) has been found to play significant roles in embryonic development, cellular proliferation and differentiation, but its role in adipogenesis has not been explored. In this study, we discovered RAI3 was downregulated during the adipogenic differentiation of human adipose derived stem cells (hASCs). Moreover, we demonstrated that knockdown of RAI3 promoted adipogenic differentiation of hASCs both in vitro and in vivo. Mechanistically, our findings showed that inhibition of RAI3 in hASCs reduced the expression of β-catenin, and lithium chloride which can activate the β-catenin pathway abolished the effect of RAI3 knockdown on the adipogenesis. These results suggest RAI3 plays an important role in adipogenesis of hASCs and may have a potential use in the future application.

Abstract
Chitin and its deacetylated form, chitosan, have been widely used for tissue engineering of both epithelial and mesenchymal tissues. Epithelial cells characterised by their sheet-like tight cellular arrangement and polarised nature, constitute a major component in various organs and play a variety of roles including protection, secretion and maintenance of tissue homeostasis. Regeneration of damaged epithelial tissues has been studied using biomaterials such as chitin, chitosan, hyaluronan, gelatin and alginate. Chitin and chitosan are known to promote proliferation of various embryonic and adult epithelial cells. However it is not clearly understood how this activity is achieved or what are the mechanisms involved in the chitin/chitosan driven proliferation of epithelial cells. Mechanistic understanding of influence of chitin/chitosan on epithelial cells will guide us to develop more targeted regenerative scaffold/hydrogel systems. Therefore, current review attempts to elicit a mechanistic insight into how chitin and chitosan interact with salivary, mammary, skin, nasal, lung, intestinal and bladder epithelial cells.

Abstract
Although abdominal wall masses are commonly observed in clinical practice, traumatic breast transposal appearing as an abdominal wall mass is a rare event. The unique phenomenon of a post-traumatic breast growing healthily in the abdominal wall has never previously been reported. The current study presents the case of a 40-year-old female who developed an unusually transposed, but healthy mammary gland in the right upper abdominal wall following a severe pedestrian traffic accident. In that accident, the powerful impact of the car caused multiple right-sided rib fractures, lung injuries and a protruding mass on the right abdominal wall. This sudden onset protruding mass was indicated to be breast tissue by computed tomography imaging and ultrasound scanning. The transposed mammary gland was resected and a pathological examination confirmed that it consisted of normal breast tissue. In this case, the force of the car caused no significant damage or necrosis to the right breast, but instead was sufficient to shift the mammary gland to the abdomen, where it grew healthily 6 months in its new location. This case highlights the capability of the mammary gland to withstand a powerful impact and survive. Moreover, it advances our knowledge of how mammary tissues respond to severe blunt-force impacts.
