Abstract
Despite the reach of in situ hybridization (ISH) in developmental biology, it is rarely used at scale. The major bottleneck is the throughput of the assay, which relies upon labor-intensive manual steps. The goal of this study was to develop a high-throughput, automated hybridization chain reaction (HCR) pipeline for the sea urchin (Lytechinus pictus). Our method, which we term high-throughput (HT)-HCR, can process 192 gene probe sets on whole-mount embryos within 32 h. The physical properties of sea urchin embryos enabled us to utilize a 96-well plate format, miniaturized reaction volumes, a general-purpose robotic liquid handler and automated confocal microscopy. Using this approach, we produced high quality localization data for 101 target genes across three developmental stages. The results reveal the localization of previously undescribed physiological genes, as well as canonical developmental transcription factors. HT-HCR represents an order of magnitude increase in the throughput of spatial expression profiling studies utilizing the sea urchin. This will enable more-sophisticated perturbation analyses and drug-screening efforts in this emerging animal model.
期刊介绍：
Development’s scope covers all aspects of plant and animal development, including stem cell biology and regeneration. The single most important criterion for acceptance in Development is scientific excellence. Research papers (articles and reports) should therefore pose and test a significant hypothesis or address a significant question, and should provide novel perspectives that advance our understanding of development. We also encourage submission of papers that use computational methods or mathematical models to obtain significant new insights into developmental biology topics. Manuscripts that are descriptive in nature will be considered only when they lay important groundwork for a field and/or provide novel resources for understanding developmental processes of broad interest to the community.
Development includes a Techniques and Resources section for the publication of new methods, datasets, and other types of resources. Papers describing new techniques should include a proof-of-principle demonstration that the technique is valuable to the developmental biology community; they need not include in-depth follow-up analysis. The technique must be described in sufficient detail to be easily replicated by other investigators. Development will also consider protocol-type papers of exceptional interest to the community. We welcome submission of Resource papers, for example those reporting new databases, systems-level datasets, or genetic resources of major value to the developmental biology community. For all papers, the data or resource described must be made available to the community with minimal restrictions upon publication.
To aid navigability, Development has dedicated sections of the journal to stem cells & regeneration and to human development. The criteria for acceptance into these sections is identical to those outlined above. Authors and editors are encouraged to nominate appropriate manuscripts for inclusion in one of these sections.
