The tergotrochanteral (TTM) "jump" muscles in the second (T2) and third (T3) thoracic segments of the fruit fly, Drosophila melanogaster, were analyzed morphologically and morphometrically in wildtype (Canton-S) and bithorax mutants (abx bx3 pbx/Df(3R)P2). In the transformed T3 segments of mutant flies, the TTMs were greatly increased in fiber number (330%(More)
Neural precursor cell (NPC) transplantation may have a role in restoring brain function after stroke, but how aging might affect the brain's receptivity to such transplants is unknown. We reported previously that transplantation of human embryonic stem cell (hESC)-derived NPCs together with biomaterial (Matrigel) scaffolding into the brains of young adult(More)
Little is known about the relationship between neuronal cell transplantation and endogenous neurogenesis after experimental stroke. We found previously that transplantation of neuronal precursors derived from BG01 human embryonic stem cells reduced infarct volume and improved behavioral outcome after distal middle cerebral artery occlusion (MCAO) in rats.(More)
Neuroglobin is a hypoxia-inducible O(2)-binding protein with neuroprotective effects in cell and animal models of stroke and Alzheimer's disease. The mechanism underlying neuroglobin's cytoprotective action is unknown, although several possibilities have been proposed, including anti-oxidative and anti-apoptotic effects. We used affinity purification-mass(More)
We investigated the spatial patterns of synaptic profiles in en passant synapses between the premotor axon of a peripherally synapsing interneuron (PAPSI) and a set of individually identifiable motoneuron axons in Drosophila melanogaster. These synaptic profiles are distributed as the axons travel parallel to each other in a bundle; the synapses begin as(More)
Endothelial cell (EC) function and susceptibility to vascular disease are regulated by flow; this relationship has been modeled in systemic, but not cerebrovascular, EC culture. We studied the effects of unidirectional flow of medium, produced by orbital rotation of cultures, on morphology and protein expression in bEnd.3 mouse brain ECs. Flow altered the(More)
