Gingiva derived-mesenchymal stem cells limited the development of autoantibodies as well as proteinuria, decreases the frequency of plasma cells and lupus nephritis histopathological scores by directly suppressing B cells activation, proliferation and differentiation.
Investigators report the ability of a scalable hollow fiber bioreactor to effectively maintain ideal mesenchymal stem cell function as a single population while also being able to impart an immunoregulatory effect when cultured in tandem with an inflamed lymphocyte population.
The authors summarize the current preclinical and clinical studies performed to investigate the regenerative potential of WJ‐MSCs in neural, myocardial, skin, liver, kidney, cartilage, bone, muscle, and other tissue injuries.
Researchers investigated the functional role of a nanosphere loaded with curcumin (CN) in the promotion of the motility of human mesenchymal stem cells (MSCs) during the skin wound healing process. They found that transplantation of umbilical cord blood-MSCs pre-treated with CN enhanced wound closure, granulation, and re-epithelialization at mouse skin wound sites.

Emmes announced that it provided the Phase III clinical trial support for a new investigational cell therapy that offers a promising treatment opportunity for patients who need an allogeneic bone marrow transplant.
PMVs from human umbilical cord (hUC) MSCs were prepared with an improved procedure including a chemical enucleation step followed by a mechanical extrusion. Plasma membrane vesicles of hUCMSCs were characterized and supplemented to hepatocyte cultures.

Compared with sham or normoxia groups, RT-PCR and western blotting showed that divalent metal transporter 1 expression was significantly increased, and Prussian blue staining, ferrous iro, MDA, and GSH level detection demonstrated that ferroptosis occurred in the infraction myocardium and in cardiomyocyte following hypoxia-induced injury.
The authors discuss recent findings on the complex nature of MSCs, focusing on their elusive impact on glioblastoma progression and aggressiveness by direct cell‐cell interaction and via secretome, also facing the perspectives and challenges in treatment strategies.
