High density multielectrode array recordings with CMOS-MEAs allow to monitor cell culture activity with unprecedent details respect to previous recording techniques. This is clarifying how network activity develops and is motivating the development of novel data analysis tools. Here, in order to advance in the exploitation of the richness of these large-scale array recordings, we introduce a principal component analysis approach that aims at improving on existing methodologies to describe neural activity events within large networks.

Blood transfusion plays a vital role in modern medicine, but frequent shortages occur. Ex vivo manufacturing of red blood cells (RBCs) from universal donor cells offers a potential solution, yet the high cost of recombinant cytokines remains a barrier. Erythropoietin (EPO) signaling is crucial for RBC development, and EPO is among the most expensive media components.

The blood-brain barrier (BBB) is a specialized network that maintains central nervous system homeostasis. Disruption of the BBB can lead to neuronal damage and contribute to neurodegenerative diseases like Parkinson's disease (PD), characterized by alpha-synuclein (αSN) aggregation, which forms intracellular inclusions. Mesenchymal stem cells (MSCs) have shown promise in alleviating the severity of neurological diseases through their paracrine secretions.

Direct SARS-CoV-2 infection of endothelial cells is challenging to study in vitro. To examine whether endothelial cell culture conditions impact the ability of SARS-CoV-2 to infect cells, we evaluated the effects of commercial cell culture media composition on SARS-CoV-2 Spike-directed viral infection. In African Green Monkey kidney epithelial cells (VeroE6), we found that commercial cell culture media (EGM2) produced inhibitory effects on recombinant vesicular stomatitis virus (rVSV-SARS-CoV-2) growth that is not seen in Dulbecco's Modified Eagle Medium (DMEM).

The assembly of tau into filaments defines tauopathies, a group of neurodegenerative diseases including Alzheimer's disease (AD), Pick's disease (PiD), corticobasal degeneration (CBD) and progressive supranuclear palsy (PSP). The seeded aggregation of tau has been modelled in cell culture using pro-aggregant modifications such as truncation of N- and C-termini and point-mutations within the microtubule-binding repeat domain. This limits the applicability of research findings to sporadic disease, where aggregates contain wild-type, full-length tau.

Objective: To investigate the role of long non-coding RNAs (lncRNAs) in the metabolic reprogramming of gastric cancer through their regulation of mesenchymal stem cells (MSCs) and HERPUD1 protein targets, aiming to elucidate mechanisms that could lead to novel therapeutic strategies.
Method: The RNA-seq was performed on BGC and hMSC-BGC cells to perform LncRNA screening. And we employed cell culture techniques using hMSC-BM and BGC823 cells, treated with various genetic interventions including siRNA and overexpression vectors.
