The establishment of porcine embryonic stem cells (ESCs) would have great impact in biomedical studies and preclinical trials through their use in genetic engineering. However, authentic porcine ESCs have not been established until now. In this study, a total of seven putative ESC lines were derived from porcine embryos of various origins, including in vitro fertilization, parthenogenetic activation, and, in particular, induced pluripotent stem (iPS) nuclear transfer (NT) from a donor cell with induced pluripotent stem cells (iPSCs). To characterize these cell lines, several assays including an assessment of intensive alkaline phosphatase activity, karyotyping, embryoid body formation, expression analysis of the pluripotency-associated markers, and the three germ layerassociated markers were performed. Based on quantitative polymerase chain reaction, the expression levels of REX1 and FGFR2 in iPS-NT lines were higher than those of cells of other origins. Additionally, only iPS-NT lines showed multiple aberrant patterns of nuclear foci elucidated by immunofluorescence staining of H3K27me3 as a marker of the state of X chromosome inactivation and a less mature form of mitochondria like naive ESCs, by transmission electron microscopy. Together, these data suggested that established putative porcine ESC lines generally exhibited a primed pluripotent state, like human ESCs. However, iPS-NT lines have especially unique characteristics distinct from other origins because they have more epigenetic instability and naive-like mitochondrial morphology than other putative ESC lines. This is the first study to establish and characterize the iPSC-derived putative ESC lines and compare them with other lines derived from different origins in pigs.

Objective: Mobilization and collection of peripheral blood stem cells (PBSCs) are time-intensive and costly. Excessive apheresis sessions can cause physical discomfort for donors and increase the costs associated with collection. Therefore, it is essential to identify key predictive factors for successful harvests to minimize the need for multiple apheresis procedures.

Effective repair of large bone defects through bone tissue engineering (BTE) remains an unmet clinical challenge. Successful BTE requires optimal and synergistic interactions among biocompatible scaffolds, osteogenic factors, and osteoprogenitors to form a highly vascularized microenvironment for bone regeneration and osseointegration. We sought to develop a highly effective BTE system by using 3D printed citrate-based mPOC/hydroxyapatite (HA) composites laden with BMP9-stimulated human urine stem cells (USCs).

Senescence and osteogenic differentiation potential loss limited bone nonunion treatment effects of bone marrow-derived mesenchymal stem cells (BMSCs). MiR-100-5p/Lysine(K)-specific demethylase 6B (KDM6B) can inhibit osteogenesis, but their effects on bone union remain unclear. This study aims to investigate the effects of miR-100-5p/KDM6B on osteogenic differentiation and bone defects.

Glioblastoma (GBM) is an aggressive brain tumor characterized by cellular and molecular diversity. This diversity presents significant challenges for treatment and leads to poor prognosis. Surgery remains the primary treatment of choice for GBMs, but it often results in tumor recurrence due to complex interactions between GBM cells and the peritumoral brain zone.
