Flowering plants have complex mechanisms that perceive ambient temperature and fine-tune flowering time. In this issue of Developmental Cell, Wu et al. reveal a mechanism of thermosensory regulation of flowering mediated by NAT10s-dependent N4-acetylcytidine modification of FLOWERING LOCUS M (FLM) transcripts to control differential alternative splicing of FLM.

Over the last decade, an unprecedented number of sequencing studies have characterized the molecular landscape of pediatric brain cancers, including the highly heterogeneous tumor medulloblastoma (MB). Extensive MB profiling has enabled a much deeper understanding of the primitive neurodevelopmental programs that are hijacked during tumor progression. However, we have yet to successfully target and fully eradicate the putative stem and early progenitor cells that drive MB tumorigenesis. This goal will require better human models that faithfully recapitulate oncogenic events, a deeper understanding of the mechanisms governing cell fate decisions in the primary and metastatic compartments, and comprehensive validation studies of MB stem/progenitor cell molecular signatures extracted from bioinformatics datasets. In this perspective, we summarize the current knowledge of the developmental origins of MB and highlight the unmet needs pertaining to tumor modeling, characterization of molecular programs driving metastatic cells, and post-transcriptional regulation of cell fate.

Vascular aging is a key driver of cardiovascular disease, yet models capturing its complexity in humans are lacking. Hutchinson-Gilford progeria syndrome (HGPS), a premature aging disorder caused by the LMNA mutation, provides a model to study accelerated vascular decline. Here, we developed a blood vessel organoid (BVO) model from HGPS-mutant human embryonic stem cells (hESCs). These BVOs model HGPS vascular defects and reveal significant downregulation of serum response factor (SRF), a trend also observed in the vasculature of naturally aged primates. We show that SRF regulates angiogenesis-related genes, and that its overexpression rescues endothelial function in HGPS organoids. In summary, we establish a 3D human organoid model of vascular aging, identify SRF as a pivotal regulator and provide a powerful platform for discovering geroprotective therapies.

The maturation of lineage-committed embryonic hepatocytes requires both the timed activation of metabolic gene regulatory networks (GRNs) and silencing of embryonic programs to achieve adult hepatic functions. However, in vitro derivation of mature hepatocytes remains imperfect, and key transcriptional regulators governing GRN rewiring during late development are still insufficiently defined. To address this, we generated a developmental reference atlas and employed a dCas9 activation screen with single-cell transcriptomics on primary mouse embryonic hepatocytes, enabling effect ranking among late-onset transcription regulators. We identify Nr1i3 as a potent inducer of pericentrally expressed metabolic genes and Nfix as a critical suppressor of embryonic and periportal signatures. Supplementing liver zonation patterning signals with these regulators further enhanced the expression of pericentrally zonated metabolic genes, emphasizing the importance of a microenvironment-targeted approach. Our screening and analysis therefore highlight regulatory mechanisms underlying organ maturation and offer general strategies for improving the functionality of in vitro-derived cells.

Microscopy offers an indispensable technique for visualizing biological processes and for defining cytological abnormalities characteristic of disease. However, combining microscopy with the power of pooled CRISPR screening presents considerable technical challenges, hindering application of systematic genetic analysis to imaging-defined phenotypes. Here, we establish a fluorescence microscopy-based CRISPR screening platform that combines ease of implementation with flexible analysis of live-cell or antibody-based molecular markers, including post-translational modifications. Applying this methodology, we systematically identify regulators of primary cilium structure and function in human cells through targeted and genome-wide screens. We further show that integration of screens focused on distinct ciliary phenotypes yields multi-dimensional profiles that delineate precise gene functions. Among the identified hits, TZMP1 (SMIM27) encodes a microprotein at the ciliary transition zone that is required for ciliogenesis in human cells and for ciliary function in Xenopus embryos. More broadly, our approach provides a technological and conceptual strategy for microscopy-based functional genomics.
