Abstract

There are a limited number of studies analyzing ovarian cancer stem cell properties. The goal of this study was to analyze the mechanical and migrational properties of ovarian cancer stem cells with the well-researched bulk ovarian cancer cells. Through the use of atomic force microscopy (AFM), the mechanical properties of both cell types were gathered. In preparation for AFM analysis, an optimal fixation method was developed and performed on the cells. AFM analysis provided mechanical properties for both cell types, including cellular stiffness, maximum adhesion force, surface area, and mean surface roughness. Cell proliferation and transwell migration assays were assessed to determine the aggressiveness of both cancer cell types. A clear trend between both cell types was expected for the mechanical and potential aggression properties. The data from both analyses were used to create a baseline for migration, proliferation, and mechanical properties of ovarian cancer stem cells and bulk ovarian cancer cells. Further studies will assess if these properties are impacted by chemotherapy exposure.

定量测定大块卵巢癌细胞和卵巢癌干细胞的力学、增殖和迁移特性

分析卵巢癌干细胞特性的研究数量有限。本研究的目的是分析卵巢癌干细胞的力学和迁移特性与大量研究的卵巢癌细胞。通过原子力显微镜（AFM），收集了两种细胞类型的力学性能。为了准备AFM分析，我们开发了一种最佳的固定方法并对细胞进行了固定。AFM分析提供了两种细胞类型的力学性能，包括细胞刚度、最大附着力、表面积和平均表面粗糙度。评估细胞增殖和跨井迁移试验以确定两种癌细胞类型的侵袭性。两种细胞类型在机械和潜在的攻击特性上有明显的趋势。这两项分析的数据被用来创建卵巢癌干细胞和散装卵巢癌细胞的迁移、增殖和力学特性的基线。进一步的研究将评估这些特性是否受到化疗暴露的影响。

期刊介绍： Acta histochemica, a journal of structural biochemistry of cells and tissues, publishes original research articles, short communications, reviews, letters to the editor, meeting reports and abstracts of meetings. The aim of the journal is to provide a forum for the cytochemical and histochemical research community in the life sciences, including cell biology, biotechnology, neurobiology, immunobiology, pathology, pharmacology, botany, zoology and environmental and toxicological research. The journal focuses on new developments in cytochemistry and histochemistry and their applications. Manuscripts reporting on studies of living cells and tissues are particularly welcome. Understanding the complexity of cells and tissues, i.e. their biocomplexity and biodiversity, is a major goal of the journal and reports on this topic are especially encouraged. Original research articles, short communications and reviews that report on new developments in cytochemistry and histochemistry are welcomed, especially when molecular biology is combined with the use of advanced microscopical techniques including image analysis and cytometry. Letters to the editor should comment or interpret previously published articles in the journal to trigger scientific discussions. Meeting reports are considered to be very important publications in the journal because they are excellent opportunities to present state-of-the-art overviews of fields in research where the developments are fast and hard to follow. Authors of meeting reports should consult the editors before writing a report. The editorial policy of the editors and the editorial board is rapid publication. Once a manuscript is received by one of the editors, an editorial decision about acceptance, revision or rejection will be taken within a month. It is the aim of the publishers to have a manuscript published within three months after the manuscript has been accepted
