Comparative transcriptomic profiling at E3-E3.5, E5-E5.5 and E8-E8.5 stages of retina development in pigeon and chicken

ABSTRACT: The macula and fovea located at the optical centre of the retina make primate visual perception unique among mammals. Pigeon retina and the human macula share a number of structural and functional properties that justify introducing the former as a new model system for retina development. Comparative transcriptome analysis of the pigeon and chicken retinas at different embryonic stages was undertaken to uncover how transcriptomic patterns translate into functional differences between the two bird species. The study showed that the pigeon’s genetic programs underlying cell differentiation are postponed until the end of the period of cell proliferation. This allows the pigeon to build a retina that displays the structural and functional traits typical of primate macula and fovea.

Transcriptome analysis of human maturing macula

Project description:The macula is an essential region of the retina responsible for visual acuity. Abnormalities in development of the fovea at the center of the macula lead to severe diseases. To identify macula-specific differentially expressed genes in maturing stage of macular development, we compared the gene expression profiles of the macular and peripheral region of the pediatric retina.

Transcriptional mapping of the macaque retina and RPE-choroid reveals conserved inter-tissue transcription drivers and signaling pathways

Project description:The macula and fovea comprise a highly sensitive visual detection tissue that is susceptible to common disease processes such as age-related macular degeneration (AMD). Unfortunately our understanding of the molecular determinants of high acuity vision remains unclear, as few model organisms possess a human-like fovea. We explore transcription factor networks and receptor-ligand interactions to elucidate tissue interactions in the macula and peripheral retina and concomitant changes in the underlying retinal pigment epithelium (RPE)/choroid.

Molecular anatomy of the developing human retina

Project description:Clinical and genetic heterogeneity associated with retinal diseases makes stem cell-based therapies an attractive strategy for personalized medicine. However, we have limited understanding of the timing of key events in the developing human retina, and in particular the factors critical for generating the unique architecture of the fovea and surrounding macula. Here we define three key epochs in the transcriptome dynamics of human retina from fetal day (D) 52 to 150. Coincident histological analyses confirmed the cellular basis of transcriptional changes and highlighted the dramatic acceleration of development in the fovea compared to peripheral retina. Human and mouse retinal transcriptomes show remarkable similarity in developmental stages, though morphogenesis was greatly expanded in humans. Integration of DNA accessibility data allowed us to reconstruct transcriptional networks controlling photoreceptor differentiation. Our studies provide insights into human retinal development and serve as resource for molecular staging of human stem cell-derived retinal organoids.

MicroRNA expression profiles in livers during pigeon (Columba livia) development

Project description:A comparative profile of miRNAs in livers during pigeon development was performed by using high-throughput sequencing. We identified known pigeon miRNAs, novel miRNAs, and miRNAs that are conserved in other birds and mammals.Our results expanded the repertoire of pigeon miRNAs and may be of help in better understanding the mechanism of squab’s rapid development from the perspective of liver development.
