Although germline cells can form multipotential embryonic stem (ES)/embryonic germ (EG) cells, these cells can be derived only from embryonic tissues, and such multipotent cells have not been available from neonatal gonads. Here we report the successful establishment of ES-like cells from neonatal mouse testis. These ES-like cells were phenotypically(More)
We evaluated the expression of the FLK1, one of the lateral mesoderm early markers where cardiogenesis occurs, to characterize and isolate cardiac stem/progenitor cells from ES cells. Dissociated cells from embryoid bodies (EBs) on day 3, 4, or 5 were collected into two subpopulations with or without FLK1 expression and coculture on OP9 stromal cells was(More)
BACKGROUND Abnormal activation of endochondral bone formation in soft tissues causes significant medical diseases associated with disability and pain. Hyperactive mutations in the bone morphogenetic protein (BMP) type 1 receptor ACVR1 lead to fibrodysplasia ossificans progressiva (FOP), a rare genetic disorder characterized by progressive ossification in(More)
Long-QT syndrome mutations can cause syncope and sudden death by prolonging the cardiac action potential (AP). Ion channels affected by mutations are various, and the influences of cellular calcium cycling on LQTS cardiac events are unknown. To better understand LQTS arrhythmias, we performed current-clamp and intracellular calcium ([Ca(2+)]i) measurements(More)
A 42-year-old woman suddenly developed weakness in her left extremities when stretching her neck two days after the onset of a nuchal pain. Because computed tomography (CT) of the brain did not show any apparent lesion, the patient had initially been treated as having a cerebral infarction until magnetic resonance imaging (MRI) of the cervical spine(More)
BACKGROUND Although prostate cancer has been prevalent in Japan, there has been no particular model for predicting the pathological stage in the Japanese population. We examined whether artificial neural network analysis (ANNA), which is a relatively new diagnostic tool in prostate cancer, can be one of the predictive methods for predicting organ(More)
BACKGROUND Little is known regarding the optimal management of a ruptured blisterlike aneurysm of the ICA. Because of the high risk for intraoperative bleeding, direct surgical treatments of these fragile lesions have generally been associated with a poor outcome. We herein report a very rare case of a ruptured blisterlike aneurysm that was successfully(More)
Purpose. To retrospectively evaluate the clinical significance of radiotherapy for oligometastases of bone in prostate cancer (PCa). Methods and Materials. Between 2003 and 2008, 35 PCa patients with oligometastases of bone were treated with radiotherapy. Results. The median radiotherapy dose was 40 Gy. The 3-year overall survival rates for all patients,(More)
The influence of the neonatal frontal lesion in unilateral cerebral hemisphere for the organization of intact forelimb motor cortex in the rat was investigated by intracortical microstimulation (ICMS). The relative size of the rostral forelimb area (RFL) compared to the caudal forelimb area (CFL) in the ipsilateral motor field of lesioned rat was(More)
OBJECTIVES We performed a phase IIa clinical trial of trans-1-amino-3-(18)F-fluoro-cyclobutane carboxylic acid (anti-(18)F-FACBC), a synthetic amino acid analog for PET, in patients with metastatic prostate cancer. METHODS The study subjects consisted of 10 untreated prostate cancer patients having lymph node and/or bone metastasis. Five patients(More)
