Cell culture has enhanced our understanding of cellular physiology and constitutes an important tool in advancing mechanistic insight. Researchers should be reminded, however, that there are limitations in extrapolating data derived from cultured cells to questions focusing on the impact of sex. In this Opinion, we highlight two underappreciated aspects of cell culture systems regarding sex: how cell culture media alters the sex hormone environment, and how the innate sex of the cell is often not factored into the overall analysis. By paying careful attention to these areas, researchers can facilitate reproducibility of their cell culture models, which is consistent with the mandate from the National Institutes of Health to improve scientific rigor and reproducibility in research.

Embryonic development during the preimplantation stages is highly sensitive and critically dependent on the reception of signaling cues. The precise coordination of diverse pathways and signaling factors is essential for successful embryonic progression. Even minor disruptions in these factors can result in physiological dysfunction, fetal malformations, or embryonic arrest.

(AMK) as an oriental medicine has been used in the treatment of threatened abortion. (AT-I) is one of the major bioactive components of AMK. This study aimed to investigate the effect of AT-I on the secretion of estradiol (E) and progesterone (P) in feline ovarian granulosa cells (FOGCs), which is necessary for pregnancy.

Canine oral melanoma (COM) is a promising target for immunomodulatory therapies aimed at enhancing the immune system's antitumor response. Given that adipose-derived mesenchymal stem cells (Ad-MSCs) possess immunomodulatory properties through cytokine release, we hypothesized that co-culturing Ad-MSCs and canine peripheral blood mononuclear cells (PBMCs) could stimulate interleukin (IL) production against melanoma cell lines (MCCLs) and help identify therapeutic targets. This study evaluated IL-2, IL-8, and IL-12 expressions in co-culture with MCCL, Ad-MSCs, and PBMCs and assessed the relationship between gene expression, cell viability, and migration.

Cyanobacteria, also known as blue-green algae, are a diverse phylum of photosynthetic, Gram-negative bacteria and one of the largest microbial taxa. These organisms produce cyanotoxins, which are secondary metabolites that can have significant impacts on both human health and the environment. While toxins like Microcystins and Cylindrospermopsins are well-documented and have been extensively studied, other cyanotoxins, including those produced by and , remain underexplored.

The vegetal alkaloid toxin veratridine (VTD) is a selective voltage-gated Na (Na) channel activator, widely used as a pharmacological tool in vascular physiology. We have previously shown that Na channels, expressed in arteries, contribute to vascular tone in mouse mesenteric arteries (MAs). Here, we aimed to better characterize the mechanisms of action of VTD using mouse cecocolic arteries (CAs), a model of resistance artery.
