Gene expression analyses reveal potential mechanism of inorganic arsenic-induced apoptosis in zebrafish 10.1002/jat.4520 Inorganic arsenic is a developmental neurotoxicant. This study using zebrafish embryos showed that inorganic arsenic altered dopaminergic neuron development and produced supernumerary motor neurons in the spinal cord via the Sonic hedgehog (Shh) pathway that is essential for motor neuron development. The results may help understand why arsenic-exposed populations suffer from psychiatric disorders and motor neuron disease.
Inorganic arsenic alters the development of dopaminergic neurons but not serotonergic neurons and induces motor neuron development via Sonic hedgehog pathway in zebrafish 10.1016/j.neulet.2022.137042 This study on zebrafish embryos suggests that the p53 pathway is likely responsible for inorganic arsenic-induced apoptosis. Inorganic arsenic significantly reduced global DNA methylation in the zebrafish embryos as has been shown in humans, which may indicate that epigenetic factors could be dysregulated.

The findings of this study demonstrated that machine learning models have a great potential to serve as alternative approaches to animal toxicity testing.
A microphysiological system-based potency bioassay for the functional quality assessment of mesenchymal stromal cells targeting vasculogenesis, Johnny Lam, Byungjun Lee ,James Yu, Brian J. Kwee, Yangji Kim, Jiho Kim, Yeongmin Choi, Jun Sung Yoon, Youngsoo Kim, Kyusuk Baek, Noo Li Jeon, Kyung E.Sung. Biomaterials 290 (2022) 121826 . 10.1016/j.biomaterials.2022.121826.
In this study, we developed a human blood vessel chips to identify mesenchymal stromal cells (MSCs) that are more likely to stimulate blood vessel regeneration via cell signaling as an alternative to the traditional murine models and in vitro scratch-based wound healing assay. People are interested in using human MSCs to treat patients with vascular diseases. However, the ability of MSCs to stimulate vessel regeneration depends on the cell lines made from donors and the manufacturing conditions used to prepare the cells for therapeutic use. This new assay might be able to help predict which MSCs will effectively stimulate vessel regeneration. This would help manufacturers make safer and more effective therapeutic products that are based on MSCs.

Co-Culture of Human Primary Hepatocytes and Nonparenchymal Liver Cells in the Emulate® Liver-Chip for the Study of Drug-Induced Liver Injury, Qiang Shi,Ayesha Arefin,Lijun Ren,Katy S. Papineau,Dustyn A. Barnette,Laura K. Schnackenberg,Jessica J. Hawes,Mark Avigan,Donna L. Mendrick,Lorna Ewart,Janey Ronxhi. Current Protocols 05 July 2022. 10.1002/cpz1.478, This link for FDA Staff only.
Current models are imperfect in identifying all drugs that cause liver injury, particularly those that affect a small percent of patients. (Those are usually found only after 1 million or more patients are exposed.) This publication provides a step-by-step description of the procedures for co-culturing of four major liver cell types of human origin in a recently developed Liver-on-a-Chip system. Our data suggest this new platform better maintains the functions than standard approaches to cultured liver cells, recapitulates some adverse responses observed in humans, and thus might serve as an improved tool for the study of liver adverse events.

Preclinical In Vitro Model to Assess the Changes in Permeability and Cytotoxicity of Polarized Intestinal Epithelial Cells during Exposure Mimicking Oral or Intravenous Routes: An Example of Arsenite Exposure. Parajuli P, Gokulan K, Khare S. International Journal of Molecular Sciences. 2022 May, 23(9), 4851. 10.3390/ijms23094851
Chemicals and drugs can cause different effects on the gut health based on whether they are given by shot in the vein (intravenous exposure) or as a pill that is swallowed (oral exposure). The authors used intestinal cells in culture and found they could assess the difference in the gut barrier function due to the exposure route. This preclinical in vitro model will reduce the use of animals for testing the impact of exposure route.
