The magnetic tweezer technique can be used to analyze the mechanical properties of cells and extracellular matrices. Scientists established a magnetic tweezer capable of measuring the linear and non-linear viscoelastic behavior of a wide range of soft matter in precisely controlled environmental conditions.
Cell culture experiments were performed in human dermal microvascular endothelial cells and included mRNA and protein analysis, and cell migration and proliferation assays. Ex vivo skin organoid culture was used to evaluate the effect of OSM on perivascular fibrosis.

iPSC cells are laboratory-produced cells that combine the biological advantages of somatic adult and stem cells for cell-based therapy. The reprogramming of cells, such as fibroblasts, to an ESC-like state is done by the ectopic expression of transcription factors responsible for generating embryonic stem cell properties.

To culture PSCs on feeder cell layers, the elimination of feeder cells is required for biological or gene analysis and for cell passage. Therefore, a simple and cost-effective cell sorting technology is required. The authors focused on dielectrophoresis phenomena for cell separation because these do not require any fluorescent or magnetic dyes or antibodies.
Investigators tested the impact of paracrine signals on human cardiomyocytes, using human pluripotent stem cell-derived cardiomyocytes as the target of mouse and human cardiac mesenchymal stromal cells with progenitor-like features.
