Abstract
Human inner ear organoids are three-dimensional tissular structures grown in vitro that recapitulate some aspects of the fetal inner ear and allow the differentiation of inner ear cell types. These organoids offer a system in which to study human inner ear development, mutations causing hearing loss and vertigo, and new therapeutic drugs. However, the extent to which such organoids mimic in vivo human inner ear development and cellular composition remains unclear. Several recent studies have performed single-cell transcriptomics on human inner ear organoids to interrogate cellular heterogeneity, reveal the developmental trajectories of sensory lineages and compare organoid-derived vesicles to the developing human inner ear. Here, we discuss the new insights provided by these analyses that help to define new paths of investigation to understand inner ear development.
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.
