Mesenchymal stem cells (MSCs) have shown potential in repairing chemotherapy-induced premature ovarian failure (POF). However, challenges such as cell loss and immune phagocytosis post-transplantation hinder their application. Due to easy safe handling, vitro culture is widely available for drug screening, pathophysiological research, fertilization. MSCs could exhibit therapeutic capacity injury, avoid tissue system. Therefore, this study utilizes an system investigate the reparative of human umbilical cord mesenchymal (hUCMSCs) mechanism.

Abstract Chronic pancreatitis (CP) is a long‐standing progressive fibrosis and has long been considered incurable, which remains heavy health burden worldwide. Mesenchymal stem cells (MSCs) with anti‐fibrosis properties are currently used in the treatment of fibroinflammatory diseases. However, its therapeutic effect limited mainly due to two main types pathological barriers CP: 1) Fibrotic collagen hinders cell delivery, 2) Malignant microenvironment attacks inactivation. Here, MSCs‐based exogenous nitric oxide (NO) delivery system (MSCs‐Lip@RNO) constructed. In MSCs‐Lip@RNO, NO not only can be booster regulate fibers, relieve vascular compression enhance accumulation MSCs whole pancreas, but also form protective gas layer on surface, enhances MSCs. CP rat model, pancreatic injury reduced 7 days after single dose administration this long‐acting Collectively, study offers promising strategy for enhancing efficacy break treatment.

Ferroptosis has been proven critical for survival following bone marrow mesenchymal stem cells (BMSCs) explantation. Suppression of ferroptosis in BMSCs will be a valid tactic to elevate the therapeutic potential engrafted BMSCs. Prominin2 is pentaspanin protein involved mediating iron efflux and thus modulates resistance ferroptosis, but its role tert-butyl hydroperoxide (TBHP)-induced remains elusive. We examined biological effect prominin2 vitro vivo by using cell proliferation assay, reactive oxygen species (ROS) examination, malondialdehyde glutathione (GSH) Western blot, quantitative reverse transcription-PCR, immunofluorescence staining gene expression inhibition activation, co-immunoprecipitation (CO-IP) radiographic analysis, histopathological analysis. Our study demonstrated that activity was impaired TBHP-induced ferroptosis. found PROM2 (encoding prominin2) activation delayed onset knockdown deteriorated course CO-IP, exerts antiferroptosis effects inhibiting BTB CNC homology 1 (BACH1) promotes ROS generation, potent antioxidant oxidative stress (OS)-induced including elevating BMSCs' rate enhancing GSH contents. with overexpression also partially progression intervertebral disk degeneration vivo, as illustrated less loss height lower histological scores. findings revealed mechanism prominin2/BACH1/ROS axis participates strengthening this promising maintain after

Abstract Myelodysplastic syndromes (MDS) are clonal hematopoietic malignancies and seriously threaten people’s health. Current therapies include bone marrow transplantation several hypomethylating agents. However, many elderly patients cannot benefit from develop drug resistance to agents, making it urgent explore novel therapy. RSL3 can effectively induce ferroptosis in various tumors combination of agents is promising treat tumors. its effect MDS was unknown. In this study, we found that inhibited cell proliferation through inducing ROS-dependent apoptosis. Bcl-2 expression increased caspase 3 PARP cleavage. RNA-seq analysis revealed MYB may be a potential target RSL3. Rescue experiments showed overexpression rescue inhibition caused by Cellular thermal shift assay binds exert function. Furthermore, tumor growth decreased vivo. More importantly, the viability mononuclear cells (BMMCs) isolated patients, had synergistic with DAC cells. Our studies have uncovered as compound MYB/Bcl-2 signaling pathway for treatment.

Human induced pluripotent stem cell derived hepatocytes (hiPSC-heps) hold promising value for acute liver failure (ALF) treatment, while their therapeutic efficacy is usually limited by low bioactivity and untargeted in vivo accumulation. Here, inspired vascularity supporting cellular architectures the tissues organs, a novel vascularized hiPSC-heps spheroid based on microfluidic microcapsules presented repair via orthotopic transplantation. The are comprised of aqueous cores that facilitate hiPSC-hep aggregating into spheroids, hybrid hydrogel shells sodium alginate hyaluronic acid methacryloyl (HAMA). By selectively degrading alginate, imparted with porous HAMA shells, which not only allowed human umbilical vein endothelial cells (HUVECs) to attach form networks, but also facilitated communication between HUVECs hiPSC-heps. specific spatial distributions these spheroids can provide nutrition support, promote hepatic functions, avoid immune attacks. Based features, it illustrated failing more effectively, indicating practical values clinical repair.
