title: CIL:1943, Caenorhabditis elegans. In Cell Image Library

description: Terminal Bulb is a dataset of DIC (differential interference contrast) 20x microscopy images of the pharynx terminal bulb of C. elegans at different ages (0, 2, 4, 6, 8, 10, 12 days). Note that the data sets for each age can be found by searching for a featured image from each set: CIL 1587, 1694, 1905, 2213, 2622, 2544, and 2606, respectively.
description: The purpose of the dataset C. elegans terminal bulb aging is to deduce the age of the nemathode based on images of the pharynx terminal bulb (part of the eating apparatus). Images of C. elegans were taken at different chronological ages. This image is part of the day 4 data set. Note that the morphological and chronological ages are not fully correlated due to the variability among individuals even though the individuals are genetically identical. The source for the dataset is Laboratory of Genetics/NIA/NIH.

title: CIL:39582, Saccharomyces cerevisiae. In Cell Image Library

description: A time lapse experiment of Saccharomyces cerevisiae expressing GFP tagged Lte1. 
 
 LTE1 is essential for termination of M phase at low temperatures, along with TEM1, and CDC15, all part of the mitotic exit network which is an elaborate signaling system comprising at least eight essential genes: CDC5, CDC14, CDC15, DBF2, DBF20, LTE1, MOB1, and TEM1. LTE1 was originally discovered as a locus essential for growth at 8 C, and was named for this trait as Low Temperature Essential 1. It was later inferred from sequence similarities that LTE1 must code for a guanine nucleotide exchange factor. Genetic evidence suggests that Lte1p activates the GTPase Tem1p which activates the protein kinase Cdc15p. Cdc15p then relieves the inhibition of the protein phosphatase Cdc14p by Net1p, thereby allowing exit from mitosis. In a normal cell cycle, Bub2p bound to Tem1p restrains mitotic exit until the daughter-bound centrosome (with which both Bub2p and Tem1p preferentially associate) comes into contact with Lte1p in the bud, effectively coupling mitotic exit with nuclear segregation. Some evidence suggests that the spatial separation of Tem1p and Lte1p is a key mechanism for controlling the timing of mitotic exit.
 
These phase,gfp z-series images are part of an image group that ranges from CIL:39581-39585. Note that there are additional groups showing time series of other cell cycle regulation proteins by the same authors in the Library.

title: CIL:36363, Rattus norvegicus, astrocyte, astrocyte of the hippocampus. In Cell Image Library

description: Male Sprague Dawley rats, 4 weeks of age, were anesthetized and perfused transcardially with with Ringer's solution (37°C), followed by 4% paraformaldehyde (PFA) in PBS (37°C, pH 7.4). Tissue was sectioned (100 µm thick) using a vibratome, and injected with a BX50WI microscope (Olympus, Melville, NY) and, using infrared differential interference contrast videomicroscopy, cells with a small diameter soma (approx. 7–11µm) in the stratum
radiatum of CA1 were located and impaled with glass micropipettes filled with 5% aq. Lucifer Yellow. The astrocytes were filled using 0.5 Hz pulses of current until all of the processes were brightly fluorescent. After several astrocytes were filled, a slice was placed in the 4% PFA overnight at 4°C. Slices were then imaged after coverslipping in Gelvatol. Confocal images were acquired with a BioRad Radiance2000 (Hercules, CA) attached to a Nikon E600FN (Kanagawa, Japan) microscope equipped with a Nikon (Tokyo, Japan) 60x oil objective (NA 1.4). Additional details are provided in Bushong EA, Martone ME, Ellisman MH. Maturation of astrocyte morphology and the establishment of astrocyte domains during postnatal hippocampal development.

title: CIL:10427, Gallus gallus, erythrocyte. In Cell Image Library

description: Nucleated erythrocytes from chicken were spread on water, the dispersed chromatin picked up on carbon-formvar grids, fixed with paraformaldehye, critical point dried and shadowed with platinum. Images were obtained with the Wisconsin high voltage TEM at 1MEV using darkfield illumination. For this micrograph, the grid was tilted to 58 degrees. A similar micrograph tilted to 43 degrees providing a stereo pair with an oblique 3D view of the tangled and irregular chromatin fibers is grouped with this image. The combination of shadowing and darkfield illumination gives a quasi-negative stain effect revealing nucleosomes in some fibers.

description: Visualization methods: confocal microscopy
description: OTHER family: The human kinome comprises 538 kinases playing essential cellular functions by catalyzing protein phosphorylations. Systematic annotation of subcellular spatial distribution of the kinome greatly facilitates investigation of normal and disease mechanisms. Here, we present Kinome Atlas (KA), an image-based map of the kinome annotated to 10 compartments of the cell. 456 epitope-tagged kinases, representing 85% of the human kinome, were expressed in HeLa cells and imaged by immunofluorescent microscopy under a unified condition. KA revealed kinase family-enriched subcellular localizations, and discovered a collection of new kinase localizations at mitochondria, plasma membrane, extracellular space, and other unique structures. This resource provides the first snapshot of the kinome under a unified condition, and is a key step toward comprehensive understanding of the spatial and temporal dynamics of the kinome in physiological and disease states.
description: Kinome Atlas documented representative images for 456 kinases expressed in HeLa cells, and visualized by immunofluorescence staining of the epitope tag. Nuclei were stained with DAPI.

title: CIL:46261, Homo sapiens. In Cell Image Library

description: Plate 25688 - Phenotypic profiling attempts to summarize multiparametric, feature-based analysis of cellular phenotypes of each sample so that similarities between profiles reflect similarities between samples. This image set provides a basis for testing image-based profiling methods wrt. to their ability to distinguish the effects of small molecules.
 
Images
The images are of U2OS cells treated with each of 1600 known bioactive compounds and labeled with six labels that characterize seven organelles (the .cell-painting. assay).
 
This pilot experiment consists of 20 plates. Each plate has 384 wells and each well has 9 fields of view for a total of 69,120 fields of view. Each field was imaged in five channels (detection wavelengths), and each channel is stored as a separate, grayscale image file, so there are 345,600 image files in 16-bit TIFF format.
description: Gustafsdottir et al. (doi:10.1371/journal.pone.0080999) have developed a multiplex cytological profiling assay that "paints the cell" with as many fluorescent markers as possible without compromising our ability to extract rich, quantitative profiles in high throughput. The assay detects seven major cellular components. In a pilot screen of bioactive compounds, the assay detected a range of cellular phenotypes and it clustered compounds with similar annotated protein targets or chemical structure based on cytological profiles. The results demonstrate that the assay captures subtle patterns in the combination of morphological labels, thereby detecting the effects of chemical compounds even though their targets are not stained directly. This image-based assay provides an unbiased approach to characterize compound- and disease-associated cell states to support future probe discovery.

Using the cell-painting assay, the Broad Institute has assembled a reference dataset of profiles for U2OS osteosarcoma cells treated with ~30,000 compounds. The compound collection includes DOS-derived compounds (20,000), as well as chemically diverse MLI compounds with biologically diverse performance identified through analysis of PubChem (10,000), and known bioactive compounds to serve as landmarks (2,500). The DOS compounds consist of structurally diverse and stereochemically rich compounds with structures distinct from the current MLSMR. The compound collection also includes 267 distinct compounds nominated by MLPCN Centers from projects for which the Centers would like to identify new chemical series with similar activities.

The experiment consists of 413 microtiter plates. Each plate has 384 wells. Each well has 9 fields of view. Each field was imaged in five channels (detection wavelengths), and each channel is stored as a separate, grayscale 16-bit TIFF image file.

description: Pathology load assessment of de-identified, human, post-mortem Alzheimer's disease and age-matched non-symptomatic donor prefrontal cortex brain tissue. We used these imaging data to inform donor stratification when we generated a large single nuclei RNA sequencing (snRNA-seq) dataset. Given we generated both imaging and snRNA-seq datasets the same location/piece of tissue for each donor, this gives us an unprecedented platform to evaluate cell type/subpopulation transcriptomes and relate them directly to their respective tissue microenvironments.
