Differentiation of human Embryonic Stem Cells (hESC) into neural progenitors as a tool to study both the pathways during early brain development and the neuroteratogenic effects of ethanol Thesis: Jelena Kostic The main objective of this work is to use human neuroprogenitors (hNPs) cells from hESC as a tool to study the cellular and molecular events involved in early human neural development under physiological conditions and to study the teratogenic effects of ethanol during the initial formation of the CNS. Specific objectives include: Objectives - Development of an in vitro protocol of derivation of human neural progenitors (hNPs) from hESCs, which could mirror early stages of human brai…
Distinct 5' SCL enhancers direct transcription to developing brain, spinal cord, and endothelium: neural expression is mediated by GATA factor bindin…

The SCL gene encodes a basic helix-loop-helix transcription factor with a pivotal role in the development of endothelium and of all hematopoietic lineages. SCL is also expressed in the central nervous system, although its expression pattern has not been examined in detail and its function in neural development is unknown. In this article we present the first analysis of SCL transcriptional regulation in vivo. We have identified three spatially distinct regulatory modules, each of which was both necessary and sufficient to direct reporter gene expression in vivo to three different regions within the normal SCL expression domain, namely, developing endothelium, midbrain, and hindbrain/spinal …
Cortical gene expression in spinal cord injury and repair: insight into the functional complexity of the neural regeneration program
2011
Traumatic spinal cord injury (SCI) results in the formation of a fibrous scar acting as a growth barrier for regenerating axons at the lesion site. We have previously shown (Klapka et al., 2005) that transient suppression of the inhibitory lesion scar in rat spinal cord leads to long distance axon regeneration, retrograde rescue of axotomized cortical motoneurons, and improvement of locomotor function. Here we applied a systemic approach to investigate for the first time specific and dynamic alterations in the cortical gene expression profile following both thoracic SCI and regeneration-promoting anti-scarring treatment (AST). In order to monitor cortical gene expression we carried out micr…
