Nestin is highly expressed in poorly differentiated and newly formed proliferating endothelial cells (ECs); however, the role of this protein in angiogenesis remains unknown. Additionally, the cytoskeleton and associated cytoskeleton-binding proteins mediate the migration of vascular ECs. Therefore, the aim of the present study was to determine whether VEGF regulates the cytoskeleton, as well a...

BACKGROUND Nestin is an intermediate filament protein that has been implicated in early stages of neuronal lineage commitment. Based on the heterogeneous expression of nestin in GBM and its potential to serve as a marker for a dedifferentiated, and perhaps more aggressive phenotype, the Radiation Therapy Oncology Group (RTOG) sought to determine the prognostic value of nestin expression in newl...

The expression of intermediate filament Nestin is necessary for the neural progenitor cells (NPCs) to maintain stemness, but the underlying cellular and molecular mechanism remains unclear. In this study, we demonstrated that Nestin is required for the self-renew of NPCs through activating MAPK and EGFR pathways. Knockdown of Nestin by shRNA inhibited cell cycle progression and proliferation in...

The neural precursor cell-specific marker nestin is expressed in fetal and adult pancreas, but its role is not fully understood. Using nestin-enhanced green fluorescent protein (EGFP) transgenic mice and fluorescence activated cell sorter, we characterized nestin-positive cells in adult mice pancreas. EGFP mRNA- and protein-positive cells expressed amylase, a pancreatic exocrine marker. Interes...

We have employed a peptide-based antibody generation protocol for producing antibody against human nestin. Using a 12-mer synthetic peptide from repetitive region of human nestin protein devoid of any N- or O-glyco-sylation sequences, we generated a mouse monoclonal antibody capable of recognizing human, mouse, bovine, and rat nestin. A wide variety of nestin proteins ranging from 140-250 kDa w...

Cancer stem cells (CSC) are unique subpopulations that have the capacity to drive malignant progression and mediate radio/chemoresistance. The role of nestin as a CSC marker in gastric adenocarcinoma is largely unknown. Our objective was to evaluate immunoexpression of CSC markers CD44 and nestin in gastric adenocarcinoma versus non-neoplastic gastric mucosae (NNGM) and correlate it with variou...

It has previously been established that skeletal muscle development is accompanied by changes in the composition of intermediate filaments: vimentin is expressed predominantly in myoblasts and desmin in adult myotubes. We show that the intermediate filament transitions during muscle development are more complex, and involve a transient expression of the recently discovered intermediate filament...

The cancer stem cell hypothesis suggests that mutated melanocyte stem cells are present in skin as precursors of melanoma cells. Nestin and CD133 have been described as markers of melanocytic stem cells. The aim of this study was to establish if melanocytic stem cells could have a prognostic significance in melanoma progression. An immunohistochemical study for nestin and CD133 was performed in...

The purpose of this study was to examine the possibility of neuronal remodeling and repair after cold-induced brain injury using immunoassay of nestin and 3CB2 (potential precursor cell markers). Male ddN strain mice were subjected to cold-induced cortical injury. Animals were divided into the following six groups: (1) 1 day after injury, (2) 1 week after injury, (3) 2 weeks after injury, (4) 1...

A specialized quiescent population of hair follicle stem cells, residing in the hair follicle outer root sheath cells (ORSCs), has previously demonstrated pluripotency for differentiation into neural stem cells (NSCs). A previous study indicated that nestin‑positive hair follicle ORSCs are able to differentiate into neurons. However, little has been reported on the isolation of nestin‑negative ...
