Mesenchymal stem cells (MSCs) are one of the most attractive cell types for cell-based bone tissue repair applications. Fetal-derived MSCs and maternal-derived MSCs have been isolated from chorionic villi of human term placenta and the decidua basalis attached to the placenta following delivery, respectively. Chorionic-derived MSCs (CMSCs) and decidua-derived MSCs (DMSCs) generated in this study met the MSCs criteria set by International Society of Cellular Therapy. These criteria include: (i) adherence to plastic; (ii) >90% expression of CD73, CD105, CD90, CD146, CD44 and CD166 combined with <5% expression of CD45, CD19 and HLA-DR; and (iii) ability to differentiate into osteogenic, adipogenic, and chondrogenic lineages. In vivo subcutaneous implantation into SCID mice showed that both bromo-deoxyuridine (BrdU)-labelled CMSCs and DMSCs when implanted together with hydroxyapatite/tricalcium phosphate particles were capable of forming ectopic bone at 8-weeks post-transplantation. Histological assessment showed expression of bone markers, osteopontin (OPN), osteocalcin (OCN), biglycan (BGN), bone sialoprotein (BSP), and also a marker of vasculature, alpha-smooth muscle actin (α-SMA). This study provides evidence to support CMSCs and DMSCs as cellular candidates with potent bone forming capacity.

Postinterventional restenosis is a major challenge in the treatment of peripheral vascular disease. Current anti-restenosis drugs inhibit neointima hyperplasia but simultaneously impair endothelial repair due to indiscrminative cytotoxity. Stem cell-derived exosomes provide multifaceted therapeutic effects by delivering functional miRNAs to endothelial cells, macrophages, and vascular smooth muscle cells (VSMCs).

Glioblastoma (GBM), notorious for its poor prognosis, stands as a formidable challenge within the central nervous system tumor category, primarily due to its intricate pathology that encompasses stemness and the epithelial-mesenchymal transition (EMT). The ubiquity of S phase kinase-associated protein 2 (Skp2) overexpression in GBM, a protein implicated in both EMT and stemness traits, correlates with increased drug resistance, elevated tumor grades, and adverse outcomes. This investigation delves into the impact of Raddeanin A (RA), a triterpenoid compound extracted from Anemone raddeana Regel, on GBM, with a special focus on its influence over Skp2 expression levels.

Mesenchymal stem cells (MSCs) are multipotent progenitor cells present in adult tissues that are recognized as promising candidates for cell therapy due to their ease of access, straightforward isolation, and capacity for bio-preservation with minimal loss of potency. However, the clinical application of MSCs faces significant challenges, such as donor site morbidity, underscoring the need for alternative sources. Recent studies have suggested that inferior turbinate tissues, which are commonly removed during turbinate surgery, may be a viable donor site for MSCs.

The EGFR-TKIs (epidermal growth factor receptor-tyrosine kinases inhibitors) offer significant benefits to lung cancer patients with sensitive EGFR mutations; however, the development of acquired resistance poses a significant challenge and leads to poor prognosis. Thus, exploring novel therapeutic strategies to overcome EGFR-TKI resistance is urgently needed. This study introduces an innovative approach utilizing folic acid-modified milk exosomes loaded with c-kit siRNA (FA-mExo-siRNA-c-kit) to target EGFR-TKI resistance in lung cancer.

Despite improvements in clinical outcomes of acute myocardial infarction (AMI), mortality rates remain high, indicating the need for further understanding of the pathogenesis and developing more effective cardiac protection strategies. Extracellular vesicles (EVs) carry proteins and noncoding RNAs (ncRNAs) derived from different cardiac cell populations, mainly including cardiomyocytes, endothelial cells, endothelial progenitor cells, cardiac progenitor cells, cardiosphere-derived cells, immune cells, fibroblasts and cardiac telocytes have vital roles under both physiological and pathological process such as myocardial infarction (MI). The content of EVs can also indicate the status of their parental cells and serve as a biomarker for monitoring the risk of cardiac injury.
