Mechanobiological Conditioning of Mesenchymal Stem Cells for Enhanced Vascular Regeneration

By means of high-throughput screening of the combinatorial space of mechanical-strain level and of the presence of particular kinase inhibitors, investigators showed that human mesenchymal stem cells could be mechanically and pharmacologically conditioned to enhance vascular regeneration in vivo.

Supervised Machine Learning for Automated Classification of Human Wharton’s Jelly Cells and Mechanosensory Hair Cells

Images from previous work, where human Wharton’s Jelly cells were differentiated into mechanosensory hair cells -like cells, were examined. Various cell features were extracted from these images, and those which were pertinent to classification were identified.

Direct Reprogramming of Epithelial Cell Rests of Malassez into Mesenchymal-Like Cells by Epigenetic Agents

Researchers examined the roles of 5-Azacytidine and valproic acid in the dedifferentiation of epithelial cell rests of Malassez into stem-like cells. Additionally, the ability of stem-like cells to differentiate into mesenchymal cells was evaluated.

Hypoxic Preconditioning of Human Umbilical Cord Mesenchymal Stem Cells Is an Effective Strategy for Treating Acute Lung Injury

When human umbilical cord MSCs were transplanted directly, only a minority of cells migrated toward damaged tissues. Moreover, their maintenance time was short, leading to unsatisfactory therapeutic results.
