Concise Review: In Vitro Formation of Bone-Like Nodules Sheds Light on the Application of Stem Cells for Bone Regeneration.

Unlabelled: : Harnessing the differentiation of stem cells into bone-forming cells represents an intriguing avenue for the creation of functional skeletal tissues. Therefore, a profound understanding of bone development and morphogenesis sheds light on the regenerative application of stem cells in orthopedics and dentistry. In this concise review, we summarize the studies deciphering the mechanisms that govern osteoblast differentiation in the context of in vitro formation of bone-like nodules, including morphologic and molecular events as well as cellular contributions to mineral nucleation, occurring during osteogenic differentiation of stem cells.

Increased internalization of Staphylococcus aureus and cytokine expression in human Wharton's jelly mesenchymal stem cells.

Background: Although a large number of studies have documented the interaction of mesenchymal stem cells (MSCs) with cells of both the innate and adaptive immune systems, not much is known about how bacteria interact with MSCs and how this might influence MSCs behavior. In this study, we investigated the impact of Staphylococcus aureus (S. aureus), on viability and cytokines' production of human Wharton's jelly-MSCs (WJ-MSCs).

Direct validation of aptamers as powerful tools to image solid tumor.

Visualization of cancer cells requires distinguishing malignant from normal cells by objective criteria with high specificity. For several years, tumor markers expressed on the surface of cancer cells have been characterized as cancer signatures, and their labeling with specific imaging probes has revolutionized cancer diagnosis. This specific labeling is also an important tool in surgery tumor ablation.
