Culture strategy as a modulator of target assessments: Functionality of suspension versus hanging drop-derived choriocarcinoma spheroids as in vitro model of embryo implantation. J Cell Biochem 2021; 122:1192-1206.

Abstract
The choriocarcinoma spheroid model has been amply applied to study the underlying molecular mechanism of implantation. Reproducibility and functionality of spheroid tumor models were addressed precisely. To mimic embryo-endometrium crosstalk, no functional characteristics of spheroids have been provided based on culture strategies. In this study, choriocarcinoma spheroids were provided as suspension culture (SC) or hanging drop culture (HDC). Primary assessments were performed based on morphology, cellular density, and hormonal secretion. Spheroid-endometrial cross talk was assessed as coculture procedures. Further, alkaline phosphatase (ALP) activity and expression of genes involved in attachment, invasion, and inducing migration were quantified. We found HDC spheroids provided a homogenous-shaped aggregate with a high grade of viability, cellular integration, hormonal secretion, and the dominant role of WNTs expression in their microarchitecture. SC spheroids showed a higher level of ALP activity and the expression of integrated genes in modulating attachment, invasion, and migration abilities. Spheroid confrontation assays clearly clarified the superiority of SC spheroids to crosstalk with epithelial and stromal cells of endometrium in addition to motivating an ideal endometrial response. Conclusively, culture strategies by affecting various molecular signaling pathways should be chosen precisely according to specific target assessments. Specifically, SC assumed as an ideal model in spheroid-endometrial cross talk.

Abstract
The near-haploid human cell line HAP1 recently became a popular subject for CRISPR/Cas9 editing, since only one allele requires modification. Through the gene-editing service at Horizon Discovery, there are at present more than 7500 edited cell lines available and the number continuously increases. The haploid nature of HAP1 is unstable as cultures become diploid with time. Here, we demonstrated some fundamental differences between haploid and diploid HAP1 cells, hence underlining the need for taking control over ploidy status in HAP1 cultures prior to phenotyping. Consequently, we optimized a procedure to determine the ploidy of HAP1 by flow cytometry in order to obtain diploid cultures and avoid ploidy status as an interfering variable in experiments. Furthermore, in order to facilitate this quality control, we validated a size-based cell sorting procedure to obtain the diploid culture more rapidly. Hence, we provide here two streamlined protocols for quality controlling the ploidy of HAP1 cells and document their validity and necessity. This article has an associated First Person interview with the co-first authors of the paper. Summary: Sharing an effective procedure to quality control the near-haploid HAP1 cells for standardized comparison to CRISPR/Cas9 modified versions and demonstrating the need for controlling the spontaneous diploidization of HAP1 cultures.

Abstract
The birth of widely available genomic databases at the turn of the millennium led to the identification of many previously unknown myosin genes and identification of novel classes of myosin, including MYO19. Further sequence analysis has revealed the unique evolutionary history of class XIX myosins. MYO19 is found in species ranging from vertebrates to some unicellular organisms, while it has been lost from some lineages containing traditional experimental model organisms. Unique sequences in the motor domain suggest class-specific mechanochemistry that may relate to its cellular function as a mitochondria-associated motor. Work over the past 10 years has demonstrated that MYO19 is an actin-activated ATPase capable of actin-based transport, and investigation of some of the conserved differences within the motor domain indicate their importance in MYO19 motor activity. The cargo-binding MyMOMA tail domain contains two distinct mechanisms of interaction with mitochondrial outer membrane components, and perturbation of MYO19 expression leads to alterations in mitochondrial movement and dynamics that impact cell function. This chapter summarizes the current state of the field and highlights potential new directions of inquiry.
