The present study was undertaken to examine multifaceted therapeutic effects of vascular endothelial growth factor (VEGF) in a rat spinal cord injury (SCI) model, focusing on its capability to stimulate proliferation of endogenous glial progenitor cells. Neural stem cells (NSCs) can be genetically modified to efficiently transfer therapeutic genes to(More)
Transplantation of neural stem cells (NSCs) has shown promise for improving functional recovery after spinal cord injury (SCI). The inhospitable milieu of injured spinal cord, however, does not support survival of grafted NSCs, reducing therapeutic efficacy of transplantation. The present study sought to examine whether overexpression of antiapoptotic gene(More)
The mechanisms of 12(S)-hydroperoxyeicosa-5Z,8Z,10E,14Z-tetraenoic acid (12(S)-HPETE)-induced scratching were studied in ICR mice. In a recent paper, we demonstrated that the 12(S)-HPETE-induced scratching was reduced not by U75302 (BLT(1) receptor antagonist), but by LY255283 (BLT(2) receptor antagonist). In the present study, we tested various compounds(More)
The molecular microenvironment of the injured spinal cord does not support survival and differentiation of either grafted or endogenous NSCs, restricting the effectiveness of the NSC-based cell replacement strategy. Studying the biology of NSCs in in vivo usually requires a considerable amount of time and cost, and the complexity of the in vivo system makes(More)
Spontaneous remyelination after spinal cord injury (SCI) is limited probably due to inadequate signaling to generate sufficient OLs from progenitor cells. The present study tested a hypothesis that introduction of olig genes, critical regulators of OL development, into immature proliferating cells could increase oligodendrogenesis after contusive SCI in(More)
The itch-associated responses evoked by intradermal injection of 12(S)-HPETE and leukotriene B4 were compared in ICR-mice. 12(S)-HPETE and leukotriene B4 (0.01-0.2 nmol/site) induced scratching of the injected site, respectively; the dose-responses were a peak at 0.05 nmol/site (12(S)-HPETE) or 0.03 nmol/site (leukotriene B4). The scratching response by(More)
Neural stem cells (NSCs) possess therapeutic potentials to reverse complex pathological processes following spinal cord injury (SCI), but many obstacles remain that could not be fully overcome by NSC transplantation alone. Combining complementary strategies might be required to advance NSC-based treatments to the clinical stage. The present study was(More)
BACKGROUND Recent advances in hyaluronic acid (HA) fillers and radiofrequency (RF) devices have been made in the context of skin rejuvenation and cosmetic surgery. Moreover, combination regimens with both techniques are currently being developed. OBJECTIVE The present study was designed to examine the clinical and histologic effects of a new needle that(More)
