Abstract
The co-culture method is a simple type of cell culture method used to evaluate the effects of communication between various types of cells in an in vitro setting. In the co-culture method, two or more eukaryotic cell types, or eukaryotic and prokaryotic cells, are cultured together. The co-culture method reflects in vivo cell behaviors and thereby emerges as a pivotal technique with diverse applications in cancer research and cell biology. Two categories of co-culture methods (indirect methods and direct methods) are well known. Direct co-culture methods allow physical contact between the various cell types (juxtacrine signaling). In indirect methods, cells are physically separated into two different populations (for example, using a Transwell) that allow communication only via secretory factors (paracrine signaling). Herein, we focus on the principles of the indirect co-culture method. Nowadays, this method is used to explore the effects of mesenchymal stem cell (MSC) secretome on cancer cells. These studies have unveiled intricate cell behavior dynamics, demonstrating how the MSC secretome influences cancer cell proliferation, invasion, apoptosis, and polarity.

Abstract
A type of three-dimensional (3D) cell culture models which is simple and easy is hanging drop method. The hanging drop method emerges as a pivotal technique with diverse applications in cancer research and cell biology. This method facilitates the formation of multicellular spheroids, providing a unique environment for studying cell behavior dynamics. The hanging drop method's theoretical underpinning relies on gravity-enforced self-assembly, allowing for cost-effective, reproducible 3D cell cultures with controlled spheroid sizes. The advantages of this approach include its efficiency in producing cellular heterogeneity, particularly in non-adherent 3D cultures, and its ability to create hypoxic spheroids, making it a suitable model for studying cancer. Moreover, the hanging drop method has proven valuable in investigating various aspects such as tissue structure, signaling pathways, immune activation of cancer cells, and notably, cell proliferation. Researchers have utilized the hanging drop method to explore the dynamics of cell proliferation, studying the effects of mesenchymal stem cells (MSC) secretome on cancer cells. The method's application involves co-culturing different cell lines, assessing spheroid formations, and quantifying their sizes over time. These studies have unveiled intricate cell behavior dynamics, demonstrating how the MSC secretome influences cancer cell growth and viability within a three-dimensional co-culture paradigm.

[PMID: 37849741 PMCID: PMC10577325 DOI: 10.3389/fcell.2023.1255697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Accepted: 09/11/2023] [Indexed: 10/19/2023] Open
Abstract
Multipotent mesenchymal stem cells (MSCs) are widely accepted as a useful tool for cell-based therapy of various diseases including malignancies. The therapeutic effects of MSCs are mainly attributed to their immunomodulatory and immunosuppressive properties. Despite the promising outcomes of MSCs in cancer therapy, a growing body of evidence implies that MSCs also show tumorigenic properties in the tumor microenvironment (TME), which might lead to tumor induction and progression. Owing to the broad-spectrum applications of MSCs, this challenge needs to be tackled so that they can be safely utilized in clinical practice. Herein, we review the diverse activities of MSCs in TME and highlight the potential methods to convert their protumorigenic characteristics into onco-suppressive effects.

Abstract
The human amniotic membrane (hAM) is the innermost layer of the placenta. Its distinctive structure and the biological and physical characteristics make it a highly biocompatible material in a variety of regenerative medicine applications. It also acts as a supply of bioactive factors and cells, which indicate the advantages over other tissues. In this review, we firstly discussed the biological properties of hAM-derived cells in vivo or in vitro, along with their stemness of markers, pointing out a promising source of stem cells for regenerative medicine. Then, we systematically summarized current knowledge on the collection, preparation, preservation, and decellularization of hAM, as well as their characteristics helping to improve the understanding of applications in tissue engineering. Finally, we highlighted the recent advances in which hAM has undergone additional modifications to achieve an adequate perspective of regenerative medicine applications. More investigations are required in utilizing appropriate modifications to enhance the therapeutic effectiveness of hAM in the future.

Abstract
One of the main causes of cancer mortality in the world is pancreatic cancer. Therapies based on stem cells are currently thought to be a hopeful option in the treatment of cancer. Herein, we intend to evaluate the antitumor effects of secretome of human amniotic mesenchymal stromal cells (hAMSCs) on autophagy and cell death induction in Panc1 pancreatic cancer cells. We adopted a co-culture system using Transwell 6-well plates and after 72 h, hAMSCs-treated Panc1 cancer cells were analyzed using quantitative real time PCR (qRT-PCR), flow cytometry, western blot, MTT assay, and DAPI staining. Based on our results, the microtubule-associated protein 1 light chain 3 (LC3) conversion from LC3-I to LC3-II and the upregulation of autophagy-related proteins expression including Beclin1, Atg7, and Atg12 were detected in hAMSCs-treated Panc1 cells. Furthermore, the level of phosphorylated proteins such as Unc-51-like kinase 1 (ULK1), AMP activated protein kinase (AMPK), AKT, and mTOR changed. Apoptotic cell death was also induced via the elevation of Bax and Caspase 3 expression and inhibition of Bcl-2. Our findings showed that secretome of hAMSCs induces autophagy and cell death in Panc1 cancer cells. However, more experiments will be needed to identify more details about the associated mechanisms.

Abstract
BACKGROUND Cancer refers to a disease resulting from the uncontrolled division and growth of abnormal cells. Among different cancer types, breast cancer is considered as one of the most commonly diagnosed cancers. Herein, we explored the therapeutic effects of human amniotic mesenchymal stromal cells (hAMSCs) secretome on breast cancer cells (MDA-MB-231) through analyzing cell cycle progression. METHODS We employed a co-culture system using 6-well Transwell plates and after 72 h, the cell cycle progression was evaluated in the hAMSCs-treated MDA-MB-231 cells through analyzing the expressions of RB, CDK4/6, cyclin D, CDK2, cyclin E, p16/INK4a, p21/WAF1/CIP1, and p27/KIP1 using quantitative real-time PCR (qRT-PCR) and western blot method. Cell proliferation, apoptosis, and cell cycle progression were checked using an MTT assay, DAPI staining, and flow cytometry. RESULTS Our results indicated that elevation of RB, p21/WAF1/CIP1, and p27/KIP1 and suppression of RB hyperphosphorylation, p16/INK4a, cyclin E, cyclin D1, CDK2, and CDK4/6 may contribute to inhibiting the proliferation of hAMSCs-treated MDA-MB-231 cells through cell cycle arrest in G1/S phase followed by apoptosis. CONCLUSION hAMSCs secretome may be an effective approach on breast cancer therapy through the inhibition of cell cycle progression.

Abstract
Colon cancer is considered as one of the main causes of mortality worldwide. Identifying a novel and more effective platform with fewer side effects is still progress. In various cancer types, Epidermal growth factor receptor (EGFR) and c-Src (a key mediator in EGFR signaling pathway) are the key targets for cancer therapy. Moreover, insulin receptor tyrosine kinase substrate (IRTKS or BAI1-associated protein 2-like 1: BAIAP2L1) is a member of the subfamily of inverse BAR (I-BAR) domain proteins, which mediates cell morphology and movement through regulation of actin polymerization. In this study, we employed a co-culture system using Transwell six-well plates. After 72 h, hAMSCs-treated HT-29 cells, EGFR, c-Src, IRTKS, p38, and ERK1/2 expression were analyzed using quantitative real time PCR (qRT-PCR) and western blot methods. The significant reduction in tumor cell growth and motility through downregulation of EGFR/c-Src/IRTKS expression and p38/ERK1/2 phosphorylation in HT-29 cells was demonstrated based on 2D and 3D cell culture models. The induction of cellular apoptosis was also found. Our results support the idea that the hAMSCS secretome has therapeutic effects on cancer cells. However, further experiments will be required to identify the exact molecular mechanisms.

Abstract
Inadequacy of most animal models for drug efficacy assessments has led to the development of improved in vitro models capable of mimicking in vivo exposure scenarios. Among others, 3D multicellular spheroid technology is considered to be one of the promising alternatives in the pharmaceutical drug discovery process. In addition to its physiological relevance, this method fulfills high-throughput and low-cost requirements for preclinical cell-based assays. Despite the increasing applications of spheroid technology in pharmaceutical screening, its application, in nanotoxicity testing is still in its infancy due to the limited penetration and uptake rates into 3D-cell assemblies. To gain a better understanding of gold nanowires (AuNWs) interactions with 3D spheroids, a comparative study of 2D monolayer cultures and 3D multicellular spheroids was conducted using two lung cancer cell lines (A549 and PC9). Cell apoptosis (live/dead assay), metabolic activity, and spheroid integrity were evaluated following exposure to AuNWs at different dose-time manners. Results revealed a distinct different cellular response between 2D and 3D cell cultures during AuNWs treatment including metabolic rates, cell viability, dose–response curves and, uptake rates. Our data also highlighted further need for more physiologically relevant tissue models to investigate in depth nanomaterial–biology interactions. It is important to note that higher concentrations of AuNWs with lower exposure times and lower concentrations of AuNWs with higher exposure times of 3 days resulted in the loss of spheroid integrity by disrupting cell–cell contacts. These findings could help to increase the understanding of AuNWs-induced toxicity on tissue levels and also contribute to the establishment of new analytical approaches for toxicological and drug screening studies.

Abstract
SGK223 is a scaffolding protein involving in the oncogenic tyrosine kinase signaling. SGK223 was phosphorylated at Y411 by c-Src and in response to the Epidermal growth factor receptor (EGFR). Tyrosine phosphorylated SGK223 at Y411 enables to interact with CSK resulting up regulation of c-Src activity and promotion of the cell migration. Human amniotic mesenchymal stromal cells (hAMSCs) are a population of multipotent cells that it was considered to be as a potential platform in cancer therapy. Herein, we employed a co-culture system to clarify the effects of hAMSCs secretome through tyrosine phosphorylation of c-Src, SGK223, AKT activity, and JAK1/Stat3 signaling in Panc1 pancreatic cancer cells. By using the 0.4 μm pore sized transwell membranes, both cell lines were firstly co-cultured for 72 h. Next, c-Src activity (tyrosine phosphorylation levels at Y530 and Y416), tyrosine phosphorylation level of SGK223 (at Y411), AKT activity, and JAK1/Stat3 signaling in Panc1 cells after treatment with hAMSCs were evaluated. Our results showed that hAMSCs have the inhibitory effects on Panc1 pancreatic cancer cells invasion and it suggests that the suppression of c-Src activity, SGK223 expression, AKT activity, and JAK1/Stat3 signaling may be as critical targets in pancreatic cancer therapy.

Abstract
Breast cancer (BC) is one of the most causes of cancer-related death among women worldwide. Cancer therapy based on stem cells was considered as a novel and promising platform. In present study, we explored the therapeutic effects of human amniotic mesenchymal stromal cells (hAMSCs) through Pinkbar (planar intestinal-and kidney-specific BAR domain protein), pAKT, and matrix metalloproteinases including MMP2, MMP9 on MDA-MB-231 breast cancer cells. To do so, we employed a co-culture system using 6 well plates transwell with a diameter of 0.4 μm pore sized. After 72h hAMSCs-treated MDA-MB-231 breast cancer cells, the expression of Epidermal growth factor receptor (EGFR), and c-Src (a key mediator in EGFR signaling pathway), Pinkbar, pAKT, MMP2, and MMP9 was analyzed by using quantitative real time PCR (qRT-PCR) and western blot methods. Based on using 2D and 3D cell culture models, the significant reduction of tumor cell growth and motility through down regulation of EGFR, c-Src, Pinkbar, pAKT, MMP2, and MMP9 in MDA-MB-231 breast cancer cells was shown. Also, the induction of cellular apoptosis also found. Our finding indicates that the hAMSCS secretome has therapeutic effects on cancer cells. To identify the details of the molecular mechanisms, more experiments will be required.
