Transcriptional profiling of retinal progenitors, exposed to endothelial cells or EGF

ABSTRACT: Retinal histogenesis occurs over an extended period, which necessitates retinal progenitors to self-renew to sustain the temporal generation of diverse cell types. Embryonic day 18 retinal cells showed self-renewal properties such as clonal propagation without compromising multipotentiality when grown in the presence of endothelial cell conditioned medium and not EGF alone.

Transcriptional profiling of retinal progenitors, exposed to endothelial cells or EGF

Project description:Retinal histogenesis occurs over an extended period, which necessitates retinal progenitors to self-renew to sustain the temporal generation of diverse cell types. Embryonic day 18 retinal cells showed self-renewal properties such as clonal propagation without compromising multipotentiality when grown in the presence of endothelial cell conditioned medium and not EGF alone. Timed pregnant Sprague Dawley (Embryonic day 18) rats were obtained from Charles River Laboratories. Embryos were harvested and enucleated. Retinae were dissected out and dissociated by trypsin-EDTA followed by manual trituration. The retinal cells obtained from 10 embryos were cultured in the presence of EGF (condition1) or EGF and Endothelial cell conditioned medium (condition 2) to obtain neurospheres. To get biological replicate for both conditions, another batch of embryos were pooled and subjected to neurosphere formation. Total RNA was extracted from both conditions using Qiagen RNeasy mini kit following manufacturer's protocol. The RNA was subjected to microarray analysis using Affymetrix Rat 230 2.0 platform by UNMC microarray Core facility. RMA analysis was performed using Genepattern software. Log2 transformed values of each condition was used to obtain fold change of specific genes.

Astrocyte-produced HB-EGF limits autoimmune CNS pathology [WGBS]

Project description:Central nervous system (CNS) resident cells such as microglia, oligodendrocytes and astrocytes are gaining increasing attention in respect to their contribution to CNS pathologies including Multiple Sclerosis (MS). Several studies have demonstrated the involvement of pro- inflammatory glial subsets in the pathogenesis and propagation of inflammatory events in MS and its animal models. However, it has only recently become clear that the underlying heterogeneity of astrocytes and microglia can not only drive inflammation, but also lead to its resolution through direct and indirect mechanisms. Failure of these tissue-protective mechanisms may potentiate disease and increase the risk of conversion to progressive stages of MS, for which currently available therapies are limited. Using proteomic analyses of cerebrospinal fluid specimens from MS patients in combination with experimental studies, we here identify Heparin-binding EGF-like growth factor (HB-EGF) as a central mediator of tissue-protective and anti-inflammatory effects important for the recovery from acute inflammatory lesions in CNS autoimmunity. Hypoxic conditions drive the rapid upregulation of HB-EGF by astrocytes during early CNS inflammation, while pro-inflammatory conditions suppress trophic HB-EGF signaling through epigenetic modifications. Finally, we demonstrate both anti-inflammatory and tissue-protective effects of HB-EGF in a broad variety of cell types in vitro and use intranasal administration of HB-EGF in acute and post-acute stages of neuroinflammation to attenuate disease in a preclinical mouse model of MS. Altogether, we identify astrocyte-derived HB-EGF and its epigenetic regulation as a novel modulator of autoimmune CNS inflammation and potential therapeutic target in MS.
