Abstract
The number of traffic deaths in Japan was 4,914 in 2009. Since the head was the most common site of injury in traffic accidents (2,302, 47%), traumatic brain injury causes the fatalities in these accidents. The aim of the present study was to quantify micro injuries in the animal bra...

Abstract
We investigated whether implantation of vascular bundles or sensory nerves affected the expression of calcitonin gene-related peptide type I receptor (CGRP1R) and neuropeptide Y1 receptor (NPY1R) in tissue-engineered bone. We implanted osteogenically induced bone marrow mesenchymal stem cells (BMSCs...

Abstract
We examine the evidence indicating that ASC can stimulate nerve regeneration by both undergoing neural differentiation and through the release of a range of growth factors. We also discuss some of the issues that need to be addressed before ASC can be developed as an effective cellular therapy for t...

Abstract
We confirmed that HP-treated adipose tissue-derived mesenchymal stem cells (HP-AT-MSCs) increased cell survival and enhanced the expression of marker genes in DsRed-engineered neural stem cells (NSCs-DsRed). Similar to untreated AT-MSCs, HP-AT-MSCs had normal morphology and were positive for the cel...

Abstract
We show that deregulation of histone deacetylase 1 (HDAC1) activity by p25/Cdk5 induces aberrant cell-cycle activity and double-strand DNA breaks leading to neurotoxicity. In a transgenic model for neurodegeneration, p25/Cdk5 activity elicited cell-cycle activity and double-strand DNA breaks that pr...
