Efficient gene delivery of a baculovirus-derived vector (BV-p53-lacZ) to a human osteogenic sarcoma cell line, Saos-2, was serendipitously found while evaluating the vector for gene delivery to human p53-null tumour cells in a previous study. Therefore, we investigated other human, rat and mouse osteogenic sarcoma and other types of tumour cell lines for transduction efficiency via baculovirus ...

The aim of the present study was to investigate the role of Semaphorin 3A (Sema3A) in the osteogenic differentiation of human alveolar bone marrow mesenchymal stem cells (hABMMSCs). To investigate whether Sema3A affects hABMMSC proliferation and osteogenic differentiation, a stable Sema3A-overexpression cell line was generated by infection with the pAdCMV-SEMA3A-MCS-EGFP vector. Cell counting k...

EVALUATION OF FIBRIN HYDROGEL SCAFFOLD EFFECT ON OSTEOGENIC DIFFERENTIATION WHARTONS’S JELLY DERIVED MESENCHYMAL STEM CELLS

It has been proven that the surface topographic cues of fiber arrangement can induce osteogenic differentiation of mesenchymal stem cells. However, this effect alone is weak and insufficient to meet the needs of regenerative medicine. In this work, electroactivity concept was introduced to enhance the osteoinductivity of fibrous scaffolds. The randomly oriented and aligned electroactive fibrous...

Abnormalities of membranous and endochondral ossification in patients with adolescent idiopathic scoliosis (AIS) remain incompletely understood. To investigate abnormalities in the melatonin signaling pathway and cellular response to melatonin in AIS, a case‑control study of osteogenic and chondrogenic differentiation was performed using human mesenchymal stem cells (hMSCs). AIS was diagnosed b...

Previous studies reported that embryonic stem cells (ESCs) can be induced to differentiate into cells showing a mature osteoblastic phenotype by culturing them under osteo-inductive conditions. It is probable that osteogenic differentiation requires that ESCs undergo differentiation through an intermediary step involving a mesenchymal lineage precursor. Based on our previous studies indicating ...

Recently, it has been reported that the orphan nuclear receptor estrogen-related receptor α (ERRα) is involved in the osteogenic differentiation of mesenchymal stem cells (MSCs). Moreover, ERRα has been identified as a novel therapeutic target for treating osteoporosis and other bone diseases. Human periodontal ligament tissue-derived mesenchymal stem cells (hPDLSCs) have recently been used in ...

Cell morphology has received considerable attention in recent years owing to its possible relationship with cell functions, including proliferation, differentiation, and migration. Recent evidence suggests that extracellular environments can also mediate cell functions, particularly cell adhesion. The aims of this study were to investigate the correlation between osteogenic differentiation acti...

Tissue-engineered bone substitutes are frequently used to repair bone defects. Adipose-derived stem cells (ASCs) are a promising source of cells for repairing bone tissue, however, insufficient osteogenic potency remains the main obstacle for their application. The present study aimed to enhance the osteogenic potency of ASCs by transfection of microRNA (miR)‑26a, a novel osteogenic and angioge...
