To further study the proliferation and multi-differentiation potentials of adipose-derived stem cells (ADSCs), the cells were isolated with improved methods and their growth curves were achieved with cck-8. Surface protein expression was analyzed by flow cytometry to characterize the cell phenotype. The multi-lineage potential of ADSCs was testified by(More)
Neural stem cells (NSCs) with the capacity of extensive self-renewal and multilineage differentiation have attracted more and more attention in research as NSCs will play an important role in the nerve disease treatment and nerve injury repair. The shortage of NSCs, both their sources and their numbers, however, is the biggest challenge for their clinic(More)
AIM To evaluate the potential of newly-developed, biocompatible iron oxide magnetic nanoparticles (MNPs) conjugated with J591, an antibody to an extracellular epitope of PSMA, to enhance MRI of prostate cancer. MATERIALS & METHODS Specific binding to PSMA by J591-MNP was investigated in vitro. MRI studies were performed on orthotopic tumor-bearing(More)
The expansion of hematopoietic stem/progenitor cells (HSPCs) from umbilical cord blood (UCB) with the support of microencapsulated osteoblasts under hypoxia environment was investigated. The expansion of HSPCs was evaluated through the total number of UCB mononuclear cells (MNCs) produced, their repopulating potential with the colony-forming unit assay(More)
Bone tissue engineering has emerged as a promising strategy in the effort to regenerate and repair diseased or damaged bone. The bioreactor, within which engineered bone tissue is cultured, plays a key role in the development of engineered bone graphs. In this work, the potentials of the rotating wall vessel bioreactor (RWVB) and the human bio-derived bone(More)
The microenvironment plays a critical role in directing the progression of stem cells into differentiated cells. So we investigated the role that cardiac microenvironment plays in directing this differentiation process. Adipose tissue-derived stem cells (ADSCs) were cultured with cardiomyocytes directly ("co-culture directly") or by cell culture insert(More)
Highly stable niosomes are prepared and investigated in Tween80/PEG6000/Span80/H2O system. The mean radius of the niosomes is 0.15-0.2 microm. The contents of PEG6000 and Span80 and the system temperature affect the size and the stability of the niosome. A certain Span80 can remarkably improve the stability. The niosome is provided distinctly with the(More)
Biochemical and mechanical signals enabling cardiac regeneration can be elucidated by using in vitro tissue engineering models. We hypothesized that human insulin-like growth factor-I (IGF-I) and 3-dimensional (3D) dynamic microenvironment could enhance the survival and differentiation of adipose tissue-derived stem cells (ADSCs). In this study, ADSCs were(More)
Induced pluripotent stem cells (iPSCs) can be generated from somatic cells by ectopic expression of defined transcription factors (TFs). However, the optimal cell type and the easy reprogramming approaches that minimize genetic aberrations of parent cells must be considered before generating the iPSCs. This paper reports a method to generate iPSCs from(More)
The architecture and biomaterial are vital for three-dimensional culture of cells in scaffolds, so collagen-chitosan scaffolds suitable for the proliferation of adipose tissue-derived stem cells (ADSCs) were fabricated in this study. Chitosan was fully mixed with collagen with different volume ratio and cross-linked. The microstructure, pore size, bibulous(More)
