Summary: Alzheimer's disease (AD) is a complex neurodegenerative disease with limited treatment options. Mesenchymal stem cell (MSC) therapy, with its ability to target multiple pathological mechanisms, has recently emerged as a potential novel treatment. However, the low brain retention efficiency of MSCs and the limited therapeutic abilities of autologous MSCs pose challenges to their effectiveness. In this study, we developed iron oxide nanoparticle (IONP)-incorporated human Wharton's jelly-derived MSCs (MSC-IONPs) to enhance their therapeutic potential. With the use of magnetic guidance, MSC-IONPs showed higher brain retention efficiency, leading to improved therapeutic efficacy in murine models of AD. Furthermore, allogeneic MSCs derived from human Wharton's jelly may offer superior therapeutic abilities compared to autologous MSCs in aged AD patients. This study provides a promising strategy for the development of MSC therapies for AD.

Summary: One promising strategy for improving cancer treatment is combination therapy, such as the use of nanoformulations containing doxorubicin and iron oxide particles covered with polymeric shells for anti-cancer activity. The study showed that the developed systems effectively inhibited human breast cancer cell growth even at low doses, while demonstrating high compatibility and lack of toxicity against various cell lines. Synergistic effects were observed with the polymer-iron oxide hybrids, suggesting potential for reducing drug toxicity and enhancing therapeutic efficiency.

Summary: In cancer treatment, mesenchymal stem cells (MSCs) exhibit tropism towards colon cancer stem cells (CCSCs), particularly CD133(+)/CD44(+) cells. When recruited by CCSCs, BMSCs transform into cancer-associated fibroblasts and secrete more IL-8, resulting in increased stemness of CCSCs. Targeting the IL-8/CXCR2 pathway in BMSCs could potentially improve therapy targeting CCSCs.

Summary: In this study, gene transfection using magnetosome-like ferrimagnetic iron oxide nanochains (MFIONs) achieved high expression of HSV-tk in MSCs and promoted gap junction intercellular communication (GJIC) between MSCs and tumor cells, leading to significantly inhibited growth of glioma through an improved bystander effect. The results suggest that iron oxide nanoparticles have the potential to enhance suicide gene expression levels in MSCs and improve the sensitivity of glioma cells to HSV-tk/GCV suicide gene therapy.

Summary: In this study, a magnetic gene complex was prepared for gene delivery to BM-MSCs. The use of UIONPs promoted gene delivery to BM-MSCs through magnetic force. Lowering the N/P ratio of free PEI reduced cytotoxicity to BM-MSCs without affecting transgene expression levels. Magnetic gene delivery enhances gene expression and reduces the required amount of PEI, providing a potential strategy for efficient and safe gene delivery to stem cells.

Summary: This study investigates the potential role and mechanisms of bone marrow-derived MSCs in colitis-associated colon cancer. Early administration of MSCs inhibits the occurrence of CAC by decreasing inflammatory cytokines and inducing Treg infiltration via TGF-beta. Late administration promotes the progression of CAC by inducing a shift in Th1/Th2 immune balance to Th2 through IL-4 secretion. The immune balance influenced by MSCs can be reversed by IL-12.

Summary: This study demonstrated the successful synthesis of greenly synthesized iron oxide nanoparticles (IONPs) from Spinacia oleracea leaf extract, coated with polyethylene glycol (PEG) and conjugated with doxorubicin (DOX). The combination of PEGylation and DOX conjugation significantly improved the cytotoxic activity of IONPs on triple-negative breast cancer.

Summary: Mesenchymal stem cells (MSCs) play a valuable role in cell-based therapy for various pathological conditions, but iron-loading can hinder their functionality and impact both allogeneic and autologous MSC therapy. Understanding MSC biology from an iron perspective is clinically significant, highlighting the importance of iron regulation for MSC physiology in health and disease.

Summary: The study aimed to understand the behavior of colon cancer cells during the initial steps of extracellular matrix invasion. The results showed that different types and concentrations of matrix substrates can affect the expression of genes and phenotypes in colon cancer cells, while drug-resistant cells exhibited weaker invasion ability.
