This entry describes a retrospective cohort of clear-cell renal cell carcinoma (ccRCC) patients from Edinburgh (NHS Lothian). A total of 120 archival nephrectomy specimens from patients with no previous treatment were included. Digital whole-slide images are available for all 120 cases stained with haematoxylin and eosin (H&E) and for 88 cases stained using multiplex immunofluorescence (mIF). The mIF panel comprised p21^CDKN1A, MCM2, and Lamin B1, with Hoechst nuclear counterstain. All slides were scanned at 20× magnification using a Zeiss Axio Scan.Z1, generating high-resolution bright-field and fluorescence images in CZI format. The dataset includes the H&E and multi-channel mIF images, derived single-cell phenotype tables, and a de-identified clinical data file. Image analysis was performed using HALO® software with AI-assisted nuclear segmentation. For each cell, fluorescence intensities of p21, MCM2, and Lamin B1 were quantified, allowing classification into proliferative (MCM2⁺) or cell-cycle arrested (p21⁺) phenotypes. Output data for each image include the proportion of p21⁺/MCM2⁻ cells and average morphological measurements such as cell and nuclear size. Quantitative results are provided in CSV format. The accompanying clinical metadata file contains pathological stage (pT), recurrence status, Fuhrman nuclear grade, ISUP grade, tumour size, nodal status, presence or absence of necrosis, derived Leibovich scores based on Fuhrman and ISUP grading (Lscore_Fuhrman and Lscore_ISUP), and disease-free survival (DFS). All data in this cohort are released under a CC0 license to permit unrestricted reuse.

This dataset consists of a paired primary–metastatic cohort comprising 62 patients with clear-cell renal cell carcinoma (ccRCC), yielding a total of 124 formalin-fixed, paraffin-embedded (FFPE) tumour samples. Each patient contributed both a primary and a metastatic sample. Haematoxylin and eosin (H&E) slides were prepared for all 124 samples, and multiplex immunofluorescence (mIF) was successfully performed for 88 of them where tissue was available for study. The mIF panel targeted key cell-cycle and microenvironmental markers — p21^CDKN1A, MCM2, and CD105 (endoglin) — with nuclear counterstaining using Hoechst 33342. Whole-slide images (WSIs) were captured using a Zeiss Axio Scan.Z1 scanner, generating high-resolution CZI files. The dataset includes all H&E and corresponding multi-channel mIF WSIs, along with derived single-cell phenotype data and de-identified clinical metadata. Quantitative outputs for each slide include the proportions of p21⁺/MCM2⁻ and CD105⁺/p21⁺/MCM2⁺ cells, as well as average cellular and nuclear morphometric parameters. The accompanying clinical CSV file provides patient-level variables including follow-up end date, survival status, follow-up duration, overall survival (OS), and progression-free survival (PFS). This cohort represents advanced-stage cases exhibiting vascular invasion or distant metastases at diagnosis. Ethical approval was granted by the Lothian Regional Ethics Committee (Refs 08/S1101/41 and 10/S1402/33). All images, quantitative data, and metadata are distributed under a CC0 license, allowing unrestricted public reuse.

Protein aggregation is a hallmark of neurodegenerative diseases and is also observed in the brains of elderly individuals without such conditions, suggesting that aging drives the accumulation of protein aggregates. However, the comprehensive understanding of age-dependent protein aggregates involved in brain aging remains unclear. Here, we investigated proteins that become sarkosyl-insoluble with age and identified hyaluronan and proteoglycan link protein 2 (HAPLN2), a hyaluronic acid-binding protein of the extracellular matrix at the nodes of Ranvier, as an age-dependent aggregating protein in mouse brains. Elevated hyaluronic acid levels and impaired microglial function reduced the clearance of HAPLN2, leading to its accumulation. HAPLN2 oligomers induced microglial inflammatory responses both in vitro and in vivo. Furthermore, age-associated HAPLN2 aggregation was also observed in the human cerebellum. These findings suggest that HAPLN2 aggregation results from age-related decline in brain homeostasis and may exacerbate the brain environment by activating microglia. This study provides new insights into the mechanisms underlying cerebellar aging and highlights the role of HAPLN2 in age-associated changes in the brain.

A comprehensive and quantitative evaluation of multiple intracellular structures or proteins is a promising approach to provide a deeper understanding of and new insights into cellular polarity. In this study, the authors developed an image analysis pipeline to obtain intensity profiles of fluorescent probes along the apical–basal axis in elongating Arabidopsis thaliana zygotes based on two-photon live-cell imaging data. This technique showed the intracellular distribution of actin filaments, mitochondria, microtubules, and vacuolar membranes along the apical–basal axis in elongating zygotes from the onset of cell elongation to just before asymmetric cell division. Hierarchical cluster analysis of the quantitative data on intracellular distribution revealed that the zygote may be compartmentalized into two parts, with a boundary located 43.6% from the cell tip, immediately after fertilization. To explore the biological significance of this compartmentalization, they examined the positions of the asymmetric cell divisions from the dataset used in this distribution analysis. They found that the cell division plane was reproducibly inserted 20.5% from the cell tip. This position corresponded well with the midpoint of the compartmentalized apical region, suggesting a potential relationship between the zygote compartmentalization, which begins with cell elongation, and the position of the asymmetric cell division.

Although StayGold is a bright and highly photostable fluorescent protein, its propensity for obligate dimer formation may hinder applications in molecular fusion and membrane targeting. To attain monovalent as well as bright and photostable labeling, the authors engineered tandem dimers of StayGold to promote dispersibility. On the basis of the crystal structure of this fluorescent protein, they disrupted the dimerization to generate a monomeric variant that offers improved photostability and brightness compared to StayGold. The authors applied the new monovalent StayGold tools to live-cell imaging experiments using spinning-disk laser-scanning confocal microscopy or structured illumination microscopy. They achieved cell-wide, high-spatiotemporal resolution and sustained imaging of dynamic subcellular events, including the targeting of endogenous condensin I to mitotic chromosomes, the movement of the Golgi apparatus and its membranous derivatives along microtubule networks, the distribution of cortical filamentous actin and the remolding of cristae membranes within mobile mitochondria.

Functionally mature neural circuits are shaped during postnatal development by eliminating redundant synapses formed during the perinatal period. In the cerebellum of neonatal rodents, each Purkinje cell (PC) receives synaptic inputs from multiple (more than 4) climbing fibers (CFs). During the first 3 postnatal weeks, synaptic inputs from a single CF become markedly larger and those from the other CFs are eliminated in each PC, leading to mono-innervation of each PC by a strong CF in adulthood. While molecules involved in the strengthening and elimination of CF synapses during postnatal development are being elucidated, much less is known about the molecular mechanisms underlying CF synapse formation during the early postnatal period. The authors show experimental evidence that suggests that a synapse organizer, PTPdelta, is required for early postnatal CF synapse formation and the subsequent establishment of CF to PC synaptic wiring. They showed that PTPdelta was localized at CF-PC synapses from postnatal day 0 (P0) irrespective of the expression of Aldolase C (Aldoc), a major marker of PC that distinguishes the cerebellar compartments. They found that the extension of a single strong CF along PC dendrites (CF translocation) was impaired in global PTPdelta knockout (KO) mice from P12 to P29-31 predominantly in PCs that did not express Aldoc [Aldoc (–) PCs].

Blood vessels show various COVID-19-related conditions including thrombosis and cytokine propagation. Existing in vitro blood vessel models cannot represent the consequent changes in the vascular structure or determine the initial infection site, making it difficult to evaluate how epithelial and endothelial tissues are damaged. Here, the authors developed a microphysiological system (MPS) that co-culture the bronchial organoids and the vascular bed to analyze infection site and interactions. In this system, virus-infected organoids caused damage in vascular structure. However, vasculature was not damaged or infected when the virus was directly introduced to vascular bed. The knockout of interferon-related genes and inhibition of the JAK/STAT pathway reduced the vascular damage, indicating the protective effect of interferon response suppression. The results demonstrate selective infection of bronchial epithelial cells and vascular damage by cytokines and also indicate the applicability of MPS to investigate how the infection influences vascular structure and functions.

Periodic organ arrangements occur during growth and development and are widespread in both animals and plants. In bilaterian animals, repetitive organs are typically arranged periodically in a two-dimensional space defined by two body axes. In contrast, radially symmetrical animals and plants exhibit organ arrangements in three-dimensional space—around the body axis in animals and around the stem in plants. While the principles of periodic organ arrangement have been extensively studied in bilaterians, investigations in radially symmetrical animals remain limited. In the present study, the authors combined live imaging, quantitative analysis, and mathematical modeling to elucidate periodic organ arrangement in a radially symmetrical animal, Coryne uchidai (Cnidaria, Hydrozoa). The polyps of C. uchidai simultaneously formed multiple tentacles in a regularly spaced, ring-like pattern exhibiting radial symmetry. Multiple such rings appeared periodically along the body and largely maintained symmetrical organization. Additionally, the researchers observed polymorphisms in symmetry types—specifically tri-, tetra-, and pentaradial symmetries—occurring as individual variations. Notably, the type of radial symmetry was positively correlated with polyp diameter, with pentaradial polyps exhibiting a larger diameter than tetra- or triradial ones. Their mathematical model suggested that the selection of size-dependent radial symmetry is governed by activation-inhibition dynamics and positional information emanating from the mouth that guides tentacle initiation.

The authors established a volumetric trans-scale imaging system with an ultra-large field-of-view (FOV) that enables simultaneous observation of millions of cellular dynamics in centimeter-wide three-dimensional (3D) tissues and embryos. Using a custom-made giant lens system with a magnification of ×2 and a numerical aperture (NA) of 0.25, and a CMOS camera with more than 100 megapixels, they built a trans-scale scope AMATERAS-2, and realized fluorescence imaging with a transverse spatial resolution of approximately 1.1 µm across an FOV of approximately 1.5×1.0 cm2. The 3D resolving capability was realized through a combination of optical and computational sectioning techniques tailored for our low-power imaging system. They applied the imaging technique to 1.2 cm-wide section of mouse brain, and successfully observed various regions of the brain with sub-cellular resolution in a single FOV. They also performed time-lapse imaging of a 1-cm-wide vascular network during quail embryo development for over 24 hr, visualizing the movement of over 4.0×105 vascular endothelial cells and quantitatively analyzing their dynamics. Their results demonstrate the potential of this technique in accelerating production of comprehensive reference maps of all cells in organisms and tissues, which contributes to understanding developmental processes, brain functions, and pathogenesis of disease, as well as high-throughput quality check of tissues used for transplantation medicine.

Understanding the factors involved in chromatin dynamics is crucial for the study of biochemical processes in which distant genomic regions need to come in close proximity. Previous single locus tracking studies suggest that chromatin dynamics are linked to active transcription, but studies which compare the chromatin dynamics of different locations within a defined chromatin domain are still very limited. Here we used the ANCHOR3 DNA labeling system to track multiple cis-regulatory elements and non-regulatory control regions at different positions in the mouse Klf4 locus. We observe homogeneous chromatin motion of cis-regulatory elements and non-cis-regulatory control regions in Klf4 transcribing mESCs and their non-transcribing EpiLCs daughter cells. These observations challenge the notion that active transcription has a major effect on the locus dynamics of mammalian genes.
