Understanding human embryology has historically relied on comparative approaches using mammalian model organisms. With the advent of low-input methods to investigate genetic and epigenetic mechanisms and efficient techniques to assess gene function, we can now study the human embryo directly. These advances have transformed the investigation of early embryogenesis in nonrodent species, thereby providing a broader understanding of conserved and divergent mechanisms. Here, we present an overview of the major events in human preimplantation development and place them in the context of mammalian evolution by comparing these events in other eutherian and metatherian species. We describe the advances of studies on postimplantation development and discuss stem cell models that mimic postimplantation embryos. A comparative perspective highlights the importance of analyzing different organisms with molecular characterization and functional studies to reveal the principles of early development. This growing field has a fundamental impact in regenerative medicine and raises important ethical considerations.

Parkinson's disease (PD) is a leading cause of neurodegeneration that is defined by the selective loss of dopaminergic neurons and the accumulation of protein aggregates called Lewy bodies (LBs). The unequivocal identification of Mendelian inherited mutations in 13 genes in PD has provided transforming insights into the pathogenesis of this disease. The mechanistic analysis of several PD genes, including α-synuclein (α-syn), leucine-rich repeat kinase 2 (LRRK2), PTEN-induced kinase 1 (PINK1), and Parkin, has revealed central roles for protein aggregation, mitochondrial damage, and defects in endolysosomal trafficking in PD neurodegeneration. In this review, we outline recent advances in our understanding of these gene pathways with a focus on the emergent role of Rab (Ras analog in brain) GTPases and vesicular trafficking as a common mechanism that underpins how mutations in PD genes lead to neuronal loss. These advances have led to previously distinct genes such as vacuolar protein-sorting-associated protein 35 (VPS35) and LRRK2 being implicated in a common signaling pathway. A greater understanding of these common nodes of vesicular trafficking will be crucial for linking other PD genes and improving patient stratification in clinical trials underway against α-syn and LRRK2 targets.

Thriving in times of resource scarcity requires an incredible flexibility of behavioral, physiological, cellular, and molecular functions that must change within a relatively short time. Hibernation is a collection of physiological strategies that allows animals to inhabit inhospitable environments, where they experience extreme thermal challenges and scarcity of food and water. Many different kinds of animals employ hibernation, and there is a spectrum of hibernation phenotypes. Here, we focus on obligatory mammalian hibernators to identify the unique challenges they face and the adaptations that allow hibernators to overcome them. This includes the cellular and molecular strategies used to combat low environmental and body temperatures and lack of food and water. We discuss metabolic, neuronal, and hormonal cues that regulate hibernation and how they are thought to be coordinated by internal clocks. Last, we touch on questions that are left to be addressed in the field of hibernation research. Studies from the last century and more recent work reveal that hibernation is not simply a passive reduction in body temperature and vital parameters but rather an active process seasonally regulated at the molecular, cellular, and organismal levels.

Polarization along an apico-basolateral axis is a hallmark of epithelial cells and is essential for their selective barrier and transporter functions, as well as for their ability to provide mechanical resiliency to organs. Loss of polarity along this axis perturbs development and is associated with a wide number of diseases. We describe three steps involved in polarization: symmetry breaking, polarity establishment, and polarity maintenance. While the proteins involved in these processes are highly conserved among epithelial tissues and species, the execution of these steps varies widely and is context dependent. We review both theoretical principles underlying these steps and recent work demonstrating how apico-basolateral polarity is established in vivo in different tissues, highlighting how developmental and physiological contexts play major roles in the execution of the epithelial polarity program. Expected final online publication date for the Annual Review of Cell and Developmental Biology, Volume 35 is October 7, 2019.

Many cellular processes rely on precise and timely deformation of the cell membrane. While many proteins participate in membrane reshaping and scission, usually in highly specialized ways, Bin/amphiphysin/Rvs (BAR) domain proteins play a pervasive role, as they not only participate in many aspects of cell trafficking but also are highly versatile membrane remodelers. Subtle changes in the shape and size of the BAR domain can greatly impact the way in which BAR domain proteins interact with the membrane. Furthermore, the activity of BAR domain proteins can be tuned by external physical parameters, and so they behave differently depending on protein surface density, membrane tension, or membrane shape. These proteins can form 3D structures that mold the membrane and alter its liquid properties, even promoting scission under various circumstances. As such, BAR domain proteins have numerous roles within the cell. Endocytosis is among the most highly studied processes in which BAR domain proteins take on important roles. Over the years, a more complete picture has emerged in which BAR domain proteins are tied to almost all intracellular compartments; examples include endosomal sorting and tubular networks in the endoplasmic reticulum and T-tubules. These proteins also have a role in autophagy, and their activity has been linked with cancer. Here, we briefly review the history of BAR domain protein discovery, discuss the mechanisms by which BAR domain proteins induce curvature, and attempt to settle important controversies in the field. Finally, we review BAR domain proteins in the context of a cell, highlighting their emerging roles in cell signaling and organelle shaping.

Phospholipids are synthesized primarily within the endoplasmic reticulum and are subsequently distributed to various subcellular membranes to maintain the unique lipid composition of specific organelles. As a result, in most cases, the steady-state localization of membrane phospholipids does not match their site of synthesis. This raises the question of how diverse lipid species reach their final membrane destinations and what molecular processes provide the energy to maintain the lipid gradients that exist between various membrane compartments. Recent studies have highlighted the role of inositol phospholipids in the nonvesicular transport of lipids at membrane contact sites. This review attempts to summarize our current understanding of these complex lipid dynamics and highlights their implications for defining future research directions.

Cellular reprogramming experiments from somatic cell types have demonstrated the plasticity of terminally differentiated cell states. Recent efforts in understanding the mechanisms of cellular reprogramming have begun to elucidate the differentiation trajectories along the reprogramming processes. In this review, we focus mainly on direct reprogramming strategies by transcription factors and highlight the variables that contribute to cell fate conversion outcomes. We review key studies that shed light on the cellular and molecular mechanisms by investigating differentiation trajectories and alternative cell states as well as transcription factor regulatory activities during cell fate reprogramming. Finally, we highlight few concepts that we believe require attention, particularly when measuring the success of cell reprogramming experiments.

Roots provide the primary mechanism that plants use to absorb water and nutrients from their environment. These functions are dependent on developmental mechanisms that direct root growth and branching into regions of soil where these resources are relatively abundant. Water is the most limiting factor for plant growth, and its availability is determined by the weather, soil structure, and salinity. In this review, we define the developmental pathways that regulate the direction of growth and branching pattern of the root system, which together determine the expanse of soil from which a plant can access water. The ability of plants to regulate development in response to the spatial distribution of water is a focus of many recent studies and provides a model for understanding how biological systems utilize positional cues to affect signaling and morphogenesis. A better understanding of these processes will inform approaches to improve crop water use efficiency to more sustainably feed a growing population.

Protein coats are supramolecular complexes that assemble on the cytosolic face of membranes to promote cargo sorting and transport carrier formation in the endomembrane system of eukaryotic cells. Several types of protein coats have been described, including COPI, COPII, AP-1, AP-2, AP-3, AP-4, AP-5, and retromer, which operate at different stages of the endomembrane system. Defects in these coats impair specific transport pathways, compromising the function and viability of the cells. In humans, mutations in subunits of these coats cause various congenital diseases that are collectively referred to as coatopathies. In this article, we review the fundamental properties of protein coats and the diseases that result from mutation of their constituent subunits.

Welcome to Volume 35 of the Annual Review of Cell and Developmental Biology (ARCDB). This issue is filled with expert reviews that synthesize, explain, and discuss the latest developments and technical advances in cell and developmental biology. Each year, the ARCDB Editorial Committee meets to discuss topics of interest and emerging areas that are “ready” for an in-depth review by one of the leaders or pioneers in the respective field. Given the centrality of the cell to all biology, choosing specific topics for inclusion in an issue can be daunting and makes discussions among the ARCDB editorial team a particularly fun and educational experience. Like all research publishing, online publishing has brought changes to how ARCDB publications are disseminated. No longer do we await the yearly printed compilation of review articles, but instead articles come online whenever the final product is ready. A hard-copy volume with all the articles in an issue is still published, but few copies are printed. The articles in the ARCDB are not yet open access, but Annual Reviews (AR) is exploring free online access options without passing on fees to authors. Recently, AR received a grant from the Robert Wood Johnson Foundation to make the Annual Review of Public Health open access. Open access to this journal launched in April 2017, and it was followed by a huge increase in usage. For example, there were 23,456 downloads from 56 countries in May 2016, before the content became open access. In May 2019, this had increased to 189,508 downloads from 137 countries. This success encouraged AR to explore sustainable open access publishing models for the entire series through an initiative called “Subscribe to Open,” which relies on the buy-in by libraries to continue to defray the cost of publication and thereby enable open access for all. Thus a benefit for all is accomplished by serving libraries’ and institutions’ interests in providing access to their researchers. As a nonprofit organization, AR operates on a balanced budget where revenues need to closely match expenditure. Thus, for AR to go open access, the Subscribe to Open model requires all libraries that presently purchase access to continue to subscribe to the series. It cannot tolerate free riders, as Subscribe to Open is financially viable only with full participation from all subscribing institutions (possibly with a dynamic price scale dependent on the size of the user pool). Other options have been discussed, but independence of the journal content and a guarantee of high quality of production, while avoiding charges to the authors, remain a priority.

{"title":"Introduction: The ARCDB in the Age of Open Access.","authors":"R. Lehmann","doi":"10.1146/annurev-cb-35-091019-100001","DOIUrl":"https://doi.org/10.1146/annurev-cb-35-091019-100001","url":null,"abstract":"Welcome to Volume 35 of the Annual Review of Cell and Developmental Biology (ARCDB). This issue is filled with expert reviews that synthesize, explain, and discuss the latest developments and technical advances in cell and developmental biology. Each year, the ARCDB Editorial Committee meets to discuss topics of interest and emerging areas that are “ready” for an in-depth review by one of the leaders or pioneers in the respective field. Given the centrality of the cell to all biology, choosing specific topics for inclusion in an issue can be daunting and makes discussions among the ARCDB editorial team a particularly fun and educational experience. Like all research publishing, online publishing has brought changes to how ARCDB publications are disseminated. No longer do we await the yearly printed compilation of review articles, but instead articles come online whenever the final product is ready. A hard-copy volume with all the articles in an issue is still published, but few copies are printed. The articles in the ARCDB are not yet open access, but Annual Reviews (AR) is exploring free online access options without passing on fees to authors.
