TOP STORYEncapsulation of human MSCs in self-assembled N-cadherin mimetic peptide hydrogels showed enhanced expression of chondrogenic marker genes and deposition of cartilage specific extracellular matrix rich in proteoglycan and type II collagen compared to control hydrogels, with a scrambled-sequence peptide after 14 days of chondrogenic culture.

PUBLICATIONS(Ranked by impact factor of the journal)IN VITROScientists revealed that the breadth of DNA methylation dynamics associated with aging and expansion is greater than previously reported. Methylation changes are enriched at known distal transcription factor binding sites such as enhancer elements, instead of CpG-rich regions, and are associated with changes in gene expression. [Stem Cell Reports] Full Article | Graphical Abstract Investigators showed that in a mouse model of doxorubicin (DOXO)-induced cardiomyopathy, C-X-C chemokine receptor type 4 (CXCR4)+ cells were increased in response to DOXO, mainly in human cardiac mesenchymal progenitor cells, a subpopulation with regenerative potential. [Cell Death Dis] Full Article Quantitative Proteomic Characterization of Lung-MSC and Bone Marrow-MSC Using DIA-Mass Spectrometry The authors present an in-depth mass spectrometry based strategy to investigate the proteomes of lung-MSC and bone marrow-MSC. [Sci Rep] Full Article Homogeneity Evaluation of Mesenchymal Stem Cells Based on Electrotaxis Analysis Researchers suggest an electrotaxis analysis as a new method to evaluate the homogeneity of mesenchymal stem cells which can observe the stem cell population in culture condition and wide use to various types of stem cells. [Sci Rep] Full Article Investigators cultured mouse bone marrow-derived MSCs on microgrooved bearing surface, partially mimicking in vivo reticulated niche, to study its effect on morphology, pluripotency factor-associated stemness, cell division and rate of proliferation. [PLoS One] Full Article Carvacrol was able to increase mesenchymal stem cell survival and migration rate. An increased activity of SOD was obtained while GPx activity unchanged or reduced. Scientists confirmed the endothelial differentiation of stem cells by detecting vWF and VE-cadherin expression. [Microvasc Res] Abstract IN VIVOA peptide-based targeting approach was established to enhance cell homing to cerebral ischemic lesion. Palmitic acid–peptide painted onto the cell membrane was able to direct MSCs to ischemic tissues without any observed cell cytotoxicity and influence on differentiation, thus reducing accumulation of cells in peripheral organs and increasing engraftment of cells in the targeted tissues. [Int J Pharm] Abstract Mesenchymal Stem Cells Correct Impaired Diabetic Wound Healing by Decreasing ECM Proteolysis Investigators demonstrated that collagen I and III protein content is significantly reduced in diabetic wounds, and treatment with MSCs significantly improved collagen I content in both non-diabetic and diabetic wounds. [Physiol Genomics] Abstract Based on a dialyzer pocket model, changes in immunological properties and the differentiation of seeded MSCs in collagen hydrogel were studied in muscle and articular cavity implantation, respectively.

POLICY NEWSIn the last few days alone, the FDA has taken steps in Florida and California to address a number of especially troubling products being marketed. But unfortunately, these are examples of a larger pool of actors who claim that their unproven and unsafe products will address a serious disease, but instead put patients at significant risk. [U.S. Food and Drug Administration] Editorial FDA Warns US Stem Cell Clinic of Significant Deviations The FDA posted a warning letter issued to US Stem Cell Clinic of Sunrise, Florida, and its Chief Scientific Officer Kristin Comella for marketing stem cell products without FDA approval and for significant deviations from current good manufacturing practice requirements, including some that could impact the sterility of their products, putting patients at risk. [U.S. Food and Drug Administration] Editorial
