Nanospheres Loaded with Curcumin Improve the Bioactivity of Umbilical Cord Blood-Mesenchymal Stem Cells via c-Src Activation during the Skin Wound Healing Process
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.

Plasma Membrane Vesicles of Human Umbilical Cord Mesenchymal Stem Cells Ameliorate Acetaminophen-Induced Damage in HepG2 Cells: A Novel Stem Cell Therapy
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.

Human Umbilical Cord Blood–Derived MSCs Exosome Attenuate Myocardial Injury by Inhibiting Ferroptosis in Acute Myocardial Infarction Mice
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.

Mesenchymal Stem Cells Offer a Drug-Tolerant and Immune-Privileged Niche to Mycobacterium tuberculosis
Investigators report that mesenchymal stem cells (MSCs) sheltered Mybacterium tuberculosis (Mtb) to help tolerate anti-TB drugs. MSCs readily took up Mtb and allowed unabated mycobacterial growth despite having a functional innate pathway of phagosome maturation.
