The postnatal forebrain subventricular zone (SVZ) harbors stem cells that give rise to olfactory bulb interneurons throughout life. The identity of stem cells in the adult SVZ has been extensively debated. Although, ependymal cells were once suggested to have stem cell characteristics, subsequent studies have challenged the initial report and postulated(More)
We have established the presence of at least two large chondroitin sulfate proteoglycans in the developing chick brain, one that reacts exclusively with HNK-1, a carbohydrate epitope found on several neural specific molecules, and one that reacts with S103L, a defined peptide epitope in the CS-2 domain of the cartilage-specific chondroitin sulfate(More)
In the premature infant, periventricular leukomalacia, usually related to hypoxicischemic white matter damage, is the main cause of neurological impairment. We hypothesized that protracted prenatal hypoxia might induce white matter damage during the perinatal period. Pregnant Sprague-Dawley rats were placed in a chamber supplied with hypoxic gas (10% O2-90%(More)
Two different chondroitin sulfate proteoglycans (CSPG) in embryonic chick brain were distinguished by immunoreactivity either with S103L, a rat monoclonal antibody which reacts specifically with an 11-amino-acid region in the chondroitin sulfate domain of the core protein of chick cartilage CSPG (Krueger, R. C., Jr., Fields, T. A., Mensch, J. R., and(More)
Proteoglycans of developing chick brain were distinguished on the basis of reactivity with four well characterized antibody reagents (S103L, to the CS-rich domain; HNK-1, to 6-sulfated glucuronic acid; 1-C-3, to the HABr region and 5-D-4, to KS chains). One chondroitin sulfate proteoglycan reacted exclusively with S103L and 1-C-3 and not with the other two(More)
Retrospective studies have shown that antenatal magnesium may decrease the risk of cerebral injury in preterm infants, leading to several ongoing trials of tocolytic magnesium as a neuroprotective agent. However, other studies have indicated that antenatal magnesium actually increases neonatal mortality, leaving it unclear if magnesium is protective or(More)
During development, the extracellular matrix (ECM) is a complex dynamic structure whose components and organization help to establish the requisite position and state of differentiation. Until recently, the large chondroitin sulfate proteoglycan, aggrecan, has been localized predominantly to skeletal tissue and considered a hallmark of cartilage(More)
