Previous studies by our group demonstrated the key role of iron in Schwann cell maturation through an increase in cAMP, PKA activation and CREB phosphorylation. These studies opened the door to further research on non-transferrin-bound iron uptake, which revealed the presence of DMT1 mRNA all along SC progeny, hinting at a constitutive role of DMT1 in ensuring the provision of iron in the PNS. ...

Low-grade myofibroblastic sarcoma (LGMFS) is a fusiform cell tumor which develops in bone or soft tissues. This type of tumor frequently occurs in the oral cavity and extremities, while it is extremely rarely found in the abdominal cavity. This article reports a case of LGMFS exceeding 20 cm in diameter in the abdominal cavity observed in a 65-year-old male patient. The patient visited our hosp...

Schwann cells (SCs) are important in the recovery of peripheral nerve injury and are valuable cells for the tissue engineering of artificial neurons. Clinical applications that require pure SCs in large quantities are limited since human and mouse SCs do not attach well to the wall of the culture dish and have low proliferative potential. To obtain high quantities of highly pure SCs, we develop...

BACKGROUND Fragile X Syndrome, the most common single gene cause of autism, results from loss of the RNA-binding protein FMRP. Although FMRP is highly expressed in neurons, it has also recently been identified in glia. It has been postulated that in the absence of FMRP, abnormal function of non-neuronal cells may contribute to the pathogenesis of the disorder. We previously demonstrated reduced...

Reactive gliosis is a glial response to a wide range of central nervous system insults, which results in cellular and molecular changes to resting glial cells. Despite its fundamental effect on neuropathologies, the identification and characterization of the molecular mechanisms underlying this process remain to be fully elucidated. The aim of the present study was to analyze the expression pro...

The pituitary is an important endocrine tissue of the vertebrate that produces and secretes many hormones. Accumulating data suggest that several types of cells compose the pituitary, and there is growing interest in elucidating the origin of these cell types and their roles in pituitary organogenesis. Therein, the histogenous cell line is an extremely valuable experimental tool for investigati...

The postnatal period is crucial for the development of gastrointestinal (GI) functions. The enteric nervous system is a key regulator of GI functions, and increasing evidences indicate that 1) postnatal maturation of enteric neurons affect the development of GI functions, and 2) microbiota-derived short-chain fatty acids can be involved in this maturation. Although enteric glial cells (EGC) are...

The biochemical and cellular changes that occur following treatment with 1-methyl-4-phenyl-1,2,3,6-tetrahyropyridine (MPTP) are remarkably similar to that seen in idiopathic Parkinson's disease (PD). PD is characterized by the degeneration of dopaminergic nigrostriatal neurons, which results in disabling motor disturbances. Activation of glial cells and the consequent neuroinflammatory response...

The dental follicle is an ectomesenchymal tissue surrounding the developing tooth germ. Human dental follicle cells (hDFCs) have the capacity to commit to differentiation into multiple cell types. Here we investigated the capacity of hDFCs to differentiate into neural cells and the efficiency of a two-step strategy involving floating neurosphere-like bodies for neural differentiation. Undiffere...

Rapid diagnosis and timely treatment improves the outcome in patients with ischemic stroke, but a rapid and sensitive blood test for ischemic stroke does not exist. This study tested whether a panel of biomarkers might be useful in the diagnosis of acute ischemic stroke. Consecutive patients with suspected stroke presenting to the emergency department of a university hospital in Korea were enro...
