Visualization and Quantification of Dynamic Intercellular Coupling in Human Embryonic Stem Cells Using Single Cell Sonoporation

The authors quantify cell–cell permeability based on dye diffusion using mass transport models. Their results revealed heterogeneous intercellular connectivity and a variety of spatiotemporal characteristics of intercellular Ca2+ waves in human ESC colonies induced by sonoporation of single cells.

Stratified Layer Analysis Reveals Intrinsic Leptin Stimulates Cryptal Mesenchymal Cells for Controlling Mucosal Inflammation

To evaluate the function of mesenchymal cells located at the large intestinal crypt, scientists established a novel method through which cells were harvested according to the histologic layers of mouse colon, and compared cellular properties between microenvironmental niches, the luminal mucosa and crypts.

Osteogenic Potential of Human Adipose Derived Stem Cells (hASCs) Seeded on Titanium Trabecular Spinal Cages

This in vitro study evaluated the adhesion, proliferation and osteogenic differentiation of adipose derived MSCs (ASCs) seeded on trabecular titanium cages. ASCs adhered, proliferated and produced an abundant extracellular matrix during the 3 weeks of culture.

Globally Altered Epigenetic Landscape and Delayed Osteogenic Differentiation in H3.3-G34W-Mutant Giant Cell Tumor of Bone

Investigators showed that in patient-derived stromal cells, H3.3-G34W was incorporated into the chromatin and associated with massive epigenetic alterations on the DNA methylation, chromatin accessibility and histone modification level, that caould be partially recapitulated in an orthogonal cell line system by the introduction of H3.3-G34W.

Sox2 Is Necessary for Androgen Ablation-Induced Neuroendocrine Differentiation from Pten Null Sca-1+/sup> Prostate Luminal Cells

Researchers provide direct genetic evidence that Sox2 is necessary for androgen ablation-induced neuroendocrine differentiation of Pten null prostate adenocarcinoma. They corroborate that the lineage status of the prostate cancer cells is a determinant for its propensity to exhibit lineage plasticity, and support that the intrinsic features of cell-of-origin for prostate cancers can dictate their clinical behaviors.
