Trophoblasts play an important role in the regulation of the development and function of the placenta. Our recent study demonstrated the skin regeneration capacity of trophoblast-derived extracellular vesicles (EV). Here, we aimed to determine the potential of trophoblast-derived conditioned medium (TB-CM) in enhancing the osteogenic differentiation of bone marrow mesenchymal stem cells (MSCs). We found that TB-CM promoted the osteogenic differentiation of MSCs in a dose-dependent manner. Furthermore, it inhibited adipogenesis of MSCs. We also found that the primary trophoblast-derived conditioned medium (PTB-CM) significantly enhanced the proliferation and osteogenic differentiation of human MSCs. Our study demonstrated the regulatory mechanisms underlying the TB-CM-induced osteogenesis in MSCs. An upregulation of genes associated with cytokines/chemokines was observed. The treatment of MSCs with TB-CM stimulated osteogenesis by activating several biological processes, such as mitogen-activated protein kinase (MAPK) and bone morphogenetic protein 2 (BMP2) signaling. This study demonstrated the proliferative and osteogenic efficacies of the trophoblast-derived secretomes, suggesting their potential for use in clinical interventions for bone regeneration and treatment.

Immune cells, such as macrophages, stimulated by several types of inorganic ions released from bioactive glasses secrete cytokines that promote and inhibit bone formation. In this study, the effects of borate-ion-stimulated mouse macrophages (RAW264) on the osteogenic differentiation of mouse bone marrow-derived mesenchymal stem cells (KUSA-A1) are investigated. KUSA-A1 is cultured with a borate-ion-containing medium and RAW264-conditioned medium, which contained the secretome released from boron-stimulated RAW264, and its osteogenic differentiation is evaluated.

Patients with metastatic colorectal cancer (mCRC) to the liver exhibit poor survival rates. Chemotherapy combined with anti-vascular therapy has emerged as the standard treatment, but resistance to anti-VEGFA therapy inevitably develops. The metabolic reprogramming of tumor vascular endothelial cells (TECs) plays a crucial, yet still poorly understood, role in the development of therapeutic resistance.

Although platelet-rich plasma (PRP) has demonstrated considerable regenerative potential in regenerative endodontic treatment, its clinical efficacy may be limited by the rapid degradation of its bioactive components, leading to inconsistent outcomes. To overcome this challenge, the present study explores the use of nano-sized exosomes derived from PRP-a novel designated as PRP exosomes (PRP-Exo)-as a more stable and targeted biomolecular delivery system to promote odontogenic differentiation within the dentin-pulp complex. The primary objective is to investigate the expression of key odontogenic markers, transforming growth factor-β1 (TGF-β1) and Dentin Sialophosphoprotein (DSPP), in human dental pulp stem cells (hDPSCs) following PRP-Exo treatment.

Yes-associated protein (YAP) is a major downstream nuclear coactivator of the Hippo pathway and is activated during myocardial hypertrophy. Verteporfin, a YAP inhibitor, may serve as a potential treatment for myocardial hypertrophy. This study was aimed at exploring the role and underlying mechanisms of verteporfin in isoproterenol (ISO)-induced myocardial hypertrophy both in vivo and in vitro.

Notably, cardiac wasting is prominent in cancer patients and cancer survivors. Cachexia studies present significant challenges due to the absence of human models and mainly short-term animal studies.
