Below are a selection of images and videos from our facility. If you have data acquired at the facility and want to show them off, please get in touch with a member of the CCI staff.

A developing kidney from an embryonic mouse can be dissociated into its constituent cells, then re-formed in the presence of other cells to study their incorporation and effect on development of the kidney. This single slice shows Six2 (cyan), Wt1-GFP (green), tubular structures (red) and podocytes in the glomeruli (magenta).
Using high-resolution AFM, the group of Luning Liu have studied, for the first time, the protein organisation, orientation and self-assembly dynamics of bacterial microcompartment shell facets.
This time-lapse video shows the embryonic development of Daphnia pulex. Creating time-lapse videos enables us to study the phenotypic changes that occur during Daphnia development.
Live assays allow us to gain an understanding of how development links to life history and how different developmental conditions can influence the variation we see in later life.
TIRF microscopy only illuminates fluorophores within ˜100nm of the coverslip. The background from the cell body is removed, therefore excellent signal to noise is achieved. Here, DLC1-GFP is imaged in TIRF (green) and epifluorescence (red) mode and the channels merged. These images were captured using our BioAFM microscope by Jennifer Francis (Sée and Lévy Lab).
Polarised light microscopy is here used as a screening tool to characterise the solid form of pharmaceutical materials. Crystalline material is birefringent, which when viewed between crossed polarisers displays bright interference colours. Amorphous material is non-birefringent and appears dark against the background.
Photothermal Imaging (AKA Laser-Induced Scattering around a NanoAbsorber) allows imaging of nanoparticles in better resolution than with light microscopy. Rama27 cells were incubated with gold nanoparticle-labelled FGF1 (Scale bar = 10 um). The magnified version shows the detection of single FGF1 proteins ("bright spots"), but also evidence for their diffusion ("streaks").

Cells respond to low oxygen levels through the action of Hypoxia Inducible Factors (HIFs). Here HIF-2α is shown to localise in nuclear 'speckles'.

Spheroids are an excellent model system for studying the biology of tumours. Here cancer cells are labelled to study how glucose metabolism alters throughout the sphere.
Large spheroids like this and even small organisms can be imaged on our Lightsheet Microscope.
Drosophila are regularly used in research to study the effect of genes on development. This dataset shows the effect of oncogenic cooperation between Ras and pico co-overexpression. Tumour cells are in green, activated JNK in red and glia in blue.
These organoids are made of porcine intestinal epithelium, grown in 3D cultures. Differentiated epithelial cell types are demonstrated by staining for tight junctions (e-cadherin), goblet cells (mucin 2), enteroendocrine cells (chromogranin A) and epithelial polarisation (villin). The green colour shows the labelled marker, f-actin is labelled red and DNA is labelled in blue.
Photothermal imaging can be used to visualise metallic nanoparticles but is also useful for the label-free imaging of Red Blood Cells in tissue sections. Here, nine adjacent fields have been stitched together to image a 5μm-thick slice of liver.
The idea behind a wound healing assay is simple: grow cells to cover a surface, scratch a 'wound' into the cells then watch the wound 'heal' (either by cell replication, migration or a combination of both).
The rate of wound healing can be quantified post-acquisition, furthermore the wound area (green) and wound edges (red) can be visualised.
There are many ways to introduce proteins, DNA or drugs into cells, few are as versatile as microinjection. At the CCI, you can microinject on the Epifluorescent Microscope.
Day 1 casper zebrafish were imaged with our Light Sheet Microscope. The aim is to measure the activity in the brain during stimulation to understand what areas and even which neurons are involved in processing information.
DIC imaging is a type of optical interferometry used to visualise differences in the optical path length. Using this technique, very finely detailed structures can be seen without the need for complicated sample preparation. In this DIC image of a HeLa cell, many structures are visible including filopodia, nucleoli, vesicles and cytoskeletal networks.
