How do ci-regulatory differences, across mouse subspecies and over evolutionary timescales, shape cell-type specification and maturation during corticogenesis? In this issue of Developmental Cell, Medina-Cano et al. establish a scalable mouse organoid platform that recapitulates developmental dynamics and enables mapping of allele-specific expression, linking cis-regulatory variation with neurodevelopmental mechanisms and disease-associated genetics.

The mechanisms by which basement membranes (BMs) adjust their mechanical properties to meet the biophysical needs of organs remain unclear. In this issue of Developmental Cell, Soh et al. establish the Caenorhabditis spermatheca as a model for repeated stretching and relaxation of the BM during the continuous ovulation process and demonstrate high, fibulin-dependent elasticity.

基底膜（basal membrane, BMs）调节其力学性能以满足器官生物物理需求的机制尚不清楚。在本期的《发育细胞》中，Soh等人建立了精膜Caenorhabditis spermatheca作为连续排卵过程中BM反复拉伸和松弛的模型，并显示出高度的纤维蛋白依赖性弹性。

KRAS mutations drive pancreatic ductal adenocarcinoma (PDAC). In this issue of Developmental Cell, Salomó Coll et al.¹ reveal that KRAS suppresses endoplasmic reticulum (ER)-phagy in pancreatic acinar cells by inhibiting CCPG1 transcription. Impaired ER-phagy triggers protein aggregation, inflammation, and acinar-to-ductal metaplasia, promoting tumorigenesis. These findings highlight selective autophagy's role in cancer, with possible therapeutic implications.

The etiology of primary hereditary microcephaly (MCPH), a condition closely linked to neocortex development, remains poorly understood. Initially, MCPH genes were thought to regulate a limited set of cellular processes, but recent studies reveal that many encode multifunctional proteins, often converging on primary cilia, organelles that orchestrate the development of most vertebrate tissues and organs. In this perspective article, we examine the role of primary cilia in brain development and explore how disruptions in MCPH and microcephaly-associated proteins compromise ciliary dynamics and function. We highlight additional cilia-related proteins with potential influence on neurodevelopment. By elucidating the connections between primary cilia and neural development, we aim to provide insights into mechanisms of neuroregeneration. Ultimately, advancing our understanding of primary cilia may help develop therapeutic strategies to restore neuronal function and improve outcomes for individuals with neurodevelopmental disorders.

原发性遗传性小头畸形（MCPH）是一种与新皮质发育密切相关的疾病，其病因尚不清楚。最初，MCPH基因被认为调节有限的细胞过程，但最近的研究表明，许多基因编码多功能蛋白质，通常聚集在初级纤毛上，这是协调大多数脊椎动物组织和器官发育的细胞器。在这篇前瞻性文章中，我们研究了初级纤毛在大脑发育中的作用，并探讨了MCPH和小头症相关蛋白的破坏如何损害纤毛的动力学和功能。我们强调了对神经发育有潜在影响的其他纤毛相关蛋白。通过阐明初级纤毛与神经发育之间的联系，我们旨在为神经再生的机制提供见解。最终，推进我们对初级纤毛的理解可能有助于制定治疗策略，以恢复神经功能并改善神经发育障碍患者的预后。

The fundamental processes of cell fate specification, differentiation, and morphogenesis must be finely synchronized to enable proper developmental progression, yet the molecular factors coordinating these processes are not well understood. A key driver of embryonic morphogenesis is the establishment of epithelial polarity, which organizes and structures the early cell layers. Here, we investigated factors controlling the epithelialization in epiblast cells and implemented sequential loss-of-function approaches in mouse embryos to define the timing of developmental significance. We found that the expression wave of the core pluripotency factors Oct4 and Sox2 following the 8-cell stage plays a critical role in this process. In this context, one of the key shared functions of these factors is to prevent premature activation of the epithelial program until the completion of the second lineage segregation. Thus, Oct4 and Sox2 simultaneously govern developmental capacity and regulate the developmental timing of tissue morphogenesis of the embryonic lineage.

细胞命运规范、分化和形态发生的基本过程必须精细同步才能实现适当的发育进程，然而协调这些过程的分子因素尚未得到很好的理解。胚胎形态发生的一个关键驱动因素是上皮极性的建立，这是早期细胞层的组织和结构。在这里，我们研究了控制外胚层细胞上皮化的因素，并在小鼠胚胎中实施了顺序功能丧失方法，以确定发育意义的时间。我们发现核心多能因子Oct4和Sox2在8细胞期之后的表达波在这一过程中起着关键作用。在这种情况下，这些因子的一个关键共享功能是防止上皮程序的过早激活，直到完成第二谱系分离。因此，Oct4和Sox2同时调控胚胎谱系组织形态发生的发育能力和发育时间。

Lineage specification requires accurate interpretation of multiple signaling cues. However, how combinatorial signaling histories influence fate outcomes remains unclear. We combined single-cell transcriptomics, live-cell imaging, and mathematical modeling to explore how activin and bone morphogenetic protein 4 (BMP4) guide fate specification during human gastrulation. We see that these signals interact both synergistically and antagonistically to drive fate decisions. We find that definitive endoderm arises from lineage convergence: a direct route from pluripotency and an indirect route via a mesoderm progenitor state. Cells pass through temporal windows of signaling competency, and the relative concentration of activin and BMP4 dictates the trajectory choice. The efficiency between routes is underpinned by a dual role of BMP4 in inducing mesoderm genes while promoting pluripotency exit. This work underscores that the combination of signals a cell is exposed to not only directs its final fate but also the developmental route taken, suggesting lineage convergence enhances robustness in fate specification.

谱系规范需要对多个信号线索进行准确的解释。然而，组合信号历史如何影响命运结果仍不清楚。我们结合单细胞转录组学、活细胞成像和数学模型来探索激活素和骨形态发生蛋白4 （BMP4）如何指导人类原肠胚形成过程中的命运规范。我们看到，这些信号相互作用，协同和对抗，以驱动命运的决定。我们发现最终的内胚层起源于谱系趋同：多能性的直接途径和中胚层祖细胞状态的间接途径。细胞通过信号能力的时间窗口，激活素和BMP4的相对浓度决定了轨迹的选择。BMP4在诱导中胚层基因和促进多能性退出的双重作用支持了途径之间的效率。这项工作强调，细胞所暴露的信号组合不仅指导其最终命运，而且还指导其所采取的发育路线，这表明谱系收敛增强了命运规范的稳健性。
