Nanovesicles In article 2300315 by Jiacan Su, Meng Li, Jie Gao, and co-workers, GelMA-NVs, defined as gelatin methacryloyl hydrogels loaded with exosome-mimicking mesenchymal stem cell-derived nanovesicles (MSC-NVs), exhibit sustained release of MSC-NVs which could increase chondrocyte human bone marrow MSC differentiation, proliferation, migration induce M2 macrophage polarization.

introduction: chemokine receptors are found on the surface of stem cells. there have been 19 distinct chemokine receptors described in mammals. chemokines are major players in migration and homing. therefore, changes in their levels or function can help us to increase the migratory potential of these cells. valproic acid differs in structure from other drugs in common use. the way in which valp...

objective(s): in this study, the effect of electrospun fiber orientation on proliferation and differentiation of mesenchymal stem cells (mscs) was evaluated. materials and methods: aligned and random nanocomposite nanofibrous scaffolds were electrospun from polylactic acid (pla), poly (vinyl alcohol) (pva) and calcium carbonate nanoparticles (ncap). the surface morphology of prepared nanofibrou...

PURPOSE Mesenchymal stem cells (MSC) are self-renewing, multipotent cells that are present in many adult tissues, including bone marrow, trabecular bone, adipose, and muscle. The presence of such cells of mesenchymal origin and their role during the wound healing of ocular injuries are currently being explored by many studies worldwide. In this study, we aimed to report the presence of mesenchy...

objective: bone marrow mesenchymal stem cells reside in bone marrow and support homing and differentiation of hematopoietic stem cells (1). this makes them an excellent instrument for regenerative treatment and co-culture with the hsc. materials and methods: in this study, k562 cell lines were treated with butyric acid(for erythroid differentiation), co-cultured with mesenchymal stem cells and ...

The contribution of distant and/or bone marrow-derived endogenous mesenchymal stem cells (MSC) to skin wounds is controversial. Bone marrow transplantation experiments employed to address this have been largely confounded by radiation-resistant host-derived MSC populations. Gestationally-acquired fetal MSC are known to engraft in maternal bone marrow in all pregnancies and persist for decades. ...

Background Mesenchymal stem cells (MSC) are adult stem cells present in bone marrow (BM), fat and in many other tissues. MSC have strong immunosuppressive qualities in vitro. The immunosuppression seems to work both by paracrine action and cell-cell contact. MSC inhibit NKcells, B-cells, dendritic cells, Th1-cells and activate regulatory T-cells. The presence of floating single MSC in human syn...

Glioblastoma is the most common and aggressive primary brain cancer. Recent isolation and characterization of brain tumor-initiating cells supports the concept that transformed neural stem cells may seed glioblastoma. We previously identified a wide array of mesenchymal tissue transcripts overexpressed in a broad set of primary glioblastoma (de novo) tumors but not in secondary glioblastoma (de...

Mesenchymal stromal/stem cells (MSCs) are a fibroblast-like cell population with high regenerative potential that can be isolated from many different tissues. Several data suggest MSCs as therapeutic tool capable of migrating to site injury and guide tissue regeneration mainly through their secretome. Pulmonary first-pass effect occurs during intravenous administration MSCs, where 50 80% the te...

The segmental premature aging disease Hutchinson-Gilford Progeria syndrome (HGPS) is caused by a truncated and farnesylated form of Lamin A called progerin. HGPS affects mesenchymal lineages, including the skeletal system, dermis, and vascular smooth muscle (VSMC). To understand the underlying molecular pathology of HGPS, we derived induced pluripotent stem cells (iPSCs) from HGPS dermal fibrob...
