Classical transplantation experiments have demonstrated that the hypostome, the oral tip of the freshwater polyp Hydra, acts as an axial organizer. Likewise, transplantation of the blastopore lip of an early Nematostella gastrula stage embryo to an aboral position leads to ectopic head formation. Following molecular analyses have shown that Wnt signaling is the key component of this organizer activity. Moreover, when dissociated and reaggregated head (and foot) organizer centres are re-established by self-organization. Similarly, \"gastruloids\", i.e. aggregates of dissociated early gastrula stage embryos, are able to self-organize. Here, we review the past and recent molecular and theoretical work in the field to explain this phenomenon. While Turing-type reaction-diffusion models involving morphogens like Wnt dominated the field for many years, recent work emphasized the importance of biophysical cues in symmetry breaking and establishment of the organizers in aggregates. The comparison with Nematostella aggregates suggests that the principles of self-organization in cnidarians is not universal.","PeriodicalId":29860,"journal":{"name":"Cells & Development","volume":" ","pages":"204024"},"PeriodicalIF":2.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143781522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

How cells transition from individual to collective behaviors as they build and remodel epithelia throughout development is a fundamental question in developmental biology. Recent studies show that three-dimensional multicellular rosettes are key intermediates that provide a solution to the challenge of building tissue-scale epithelia by coordinating local interactions in small groups of cells. These radially polarized rosette structures facilitate epithelial formation by providing a protected environment for cells to acquire apical-basal polarity, establish cell adhesion, and coordinate intercellular signaling. Once formed, rosettes can dynamically expand, move, coalesce, and interact with surrounding tissues to generate a wide range of structures with specialized functions, including epithelial sheets, tubes, cavities, and branched networks. In this review, we describe the mechanisms that regulate rosette assembly and dynamics, and discuss how rosettes serve as versatile intermediates in epithelial morphogenesis. In addition, we present open questions about the molecular, cellular, and biophysical mechanisms that drive rosette behaviors, and discuss the implications of this widely used mode of epithelial formation for understanding embryonic development and human disease.","PeriodicalId":29860,"journal":{"name":"Cells & Development","volume":" ","pages":"204022"},"PeriodicalIF":2.1,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143693686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A conserved vertebrate mechanism involves the regulation of a ventral-to-dorsal BMP activity gradient during gastrulation by the organizer-expressed molecules. In zebrafish, BMP signaling controls mesodermal cell convergence and extension (C&E) by inhibiting Planar Cell Polarity (PCP) signaling and regulating cell adhesion. This allows lateral cells to converge toward the dorsal midline while directing ventral cells toward the tail bud. However, BMP's role in endodermal cell movements and the temporal precision of its regulatory functions remain poorly understood. Using optogenetics and other loss- and gain-of-function approaches, we investigated BMP's role in mesoderm and endoderm C&E. We found that low BMP signaling promotes extension in both germ layers, whereas high BMP signaling inhibits their C&E. Remarkably, BMP signaling activation for 1 h rapidly redirected dorsal to ventral migration of both mesodermal and endodermal cells. However, when BMP signaling was selectively elevated in endoderm in embryos with reduced BMP signaling, endoderm still mimicked mesodermal cell movements, indicating that endodermal responses to BMP are non-cell autonomous. We show that movements of endodermal cells in gastrulae with normal or elevated BMP signaling are not entirely dependent on mesoderm or the Cxcl12b/Cxcr4a GPCR pathway, suggesting additional mechanisms underlie endoderm C&E. Our findings highlight the critical role of the BMP morphogen gradient in coordinated C&E movements of mesodermal and endodermal cells. BMP employs both direct and indirect mechanisms to ensure robust embryonic patterning and morphogenesis of germ layers.","PeriodicalId":29860,"journal":{"name":"Cells & Development","volume":" ","pages":"204021"},"PeriodicalIF":2.1,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143639900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hunt for genes and the elucidation of their biochemical outputs has organized funding in research, educational curricula, academic promotion, and the distribution of prestige through awards. Such reductionism has gone hand in hand with an ontology of the machine. We will discuss how viewing life as if it emanated from a set of molecular machines is the main bottleneck in addressing key questions in biology. We will discuss how moving beyond it is not contingent on new technologies but rather a refreshed perspective of life that can be termed \"organic\". Furthermore, we suggest that the study of how form arises, morphogenesis, is the key to an organic renewal of biology and biomedicine. Although morphogenesis is currently seen as a subsidiary branch of developmental biology as well as the consequence of molecular patterning processes at the subcellular scale, we will argue that morphology and its self-organizing capacity at the supracellular scale is the fundamental nexus in embryonic development as well as disease. We see the inability to appreciate form through an organic supracellular perspective as the principal bottleneck for making inroads into health issues such as cancer and the chronic disease epidemic.","PeriodicalId":29860,"journal":{"name":"Cells & Development","volume":" ","pages":"204018"},"PeriodicalIF":2.1,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143617433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A milestone in this field was achieved in 1924 when Hans Spemann and Hilde Mangold discovered the dorsal organizer for embryonic body axis formation in amphibians. Since then, extensive studies have demonstrated that the dorsal organizer is evolutionarily conserved in vertebrates. This organizer functions as a signaling center, directing adjacent cells toward specific fates and orchestrating pattern formation to establish the embryonic axis. After 70 years since the discovery of the organizer, studies in different model animal species had revealed that locally activated β-catenin signaling during blastulation plays an indispensable role in organizer induction. Then, efforts have been made to identify initiators of β-catenin activation in blastulas. Now, it appears that maternal Huluwa, a transmembrane protein, is a bona fide organizer inducer at least in teleost fish and frog, which can activate downstream signaling pathways, including but probably not limited to β-catenin pathway. More studies are needed to decode the complete molecular network controlling organizer induction.","PeriodicalId":29860,"journal":{"name":"Cells & Development","volume":" ","pages":"204020"},"PeriodicalIF":2.1,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143587391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During evolution, functional adaptations in organs are significantly influenced by changes in cell type compositions, and in diseases, aberrations in cell type compositions result in impaired organ functions. Investigating the mechanisms that regulate cell type compositions could elucidate an important organizational meta-level that bridges gene functions and cellular features de facto facilitating the emergence of collective cell behaviors and novel tissue functions. Due to their unique evolutionary positioning and diverse functions, mucociliary epithelia could provide an optimal system to unravel principle mechanisms of adaptations in cell type compositions that facilitate the evolution of new or optimization of existing tissue functions, and could reveal novel entry points to counteract human diseases. An integrative investigation of signaling, transcriptional, epigenetic and morphogenetic mechanisms across a broad range of mucociliary tissues with different specialized cells and cell type compositions can help us to connect gene functions and contributions to self-organized behaviors in cell collectives determining emergent tissue functions. Taking such route moving forward has the potential to unravel novel principles in mucociliary self-organization and to reveal broadly applicable principles underlying the generation and modification of emergent tissue functions across species and organ systems.","PeriodicalId":29860,"journal":{"name":"Cells & Development","volume":" ","pages":"204019"},"PeriodicalIF":2.1,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143587340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While many papers have investigated, and many others reviewed, the signalling aspects of the organizer, relatively fewer have concentrated on the cell biology of organizer cells. Here we survey more than 12 decades of knowledge on the chick organizer, including the cellular origins, fates, composition, cell movements, cell population properties and molecular dynamics of the chick organizer (the tip of the primitive streak). What emerges is a picture of an extremely complex and dynamic population of cells whose properties change over space and time, quite different from the \"textbook\" view of a static group of cells set aside during early development to perform a particular function in the normal embryo before being swept aside. Some of these findings also have more general implications for the interpretation of results from single cell RNA sequencing experiments.","PeriodicalId":29860,"journal":{"name":"Cells & Development","volume":" ","pages":"204017"},"PeriodicalIF":2.1,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143568445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
