STED microscopy reveals details beyond the diffraction barrier, paving the way to new biological insights.

Tale of tails- development of an early zebrafish tailbud - by Martyna Lukoseviviute

Analysis of Nanobodies using Surface Plasmon Resonance by Martin Fellermeyer

Depicted are real-time binding curves of nanobodies analysed by SPR using the Biacore 8K. Parts of the machine are seen on the right.

Langerhans Cells in healthy skin - by Randeep Singh

Langerhans cells (LC) are tissue-resident DCs found in the epidermal layer of the skin. CD1a is an MHC class - I like protein abundantly expressed on LCs. LCs have crucial roles in immune surveillance and homeostasis, however, lipid antigens presented by CD1a has been shown to amplify inflammatory responses in skin inflammation. The image shows CD1a staining on LCs in healthy skin – the dendrites protruding in the epidermal layer sensing for antigens

Megakaryocytes on a 2D monolayer of endothelium -by Abdullah Khan

Megakaryocytes (green) are imaged on a monolayer of endothelial cells (magenta) with which they interact to generate platelets.

Co-culture of tumour cells (red cells) on top of a layer of endothelial cells (image acquired using bright-field microscopy at WIMM)

Vascular Organoids- by Abdullah Khan

Induced pluripotent stem cells (iPSC) can be used to generate primitive ‘organoids’ which reproduce physiological structures, and allow us to more accurately study disease pathologies. Here, iPSCs are differentiated to mak a vascularised organoid which we use to study the effects of Covid19 on the microvasculature.

X marks the Spot- by Louise Johnson

Whole mount immunofluorescence confocal microscopy of a junction between endothelial cells of a lymphatic vessel within mouse dermis. Individual lymphatic endothelial cells overlap, with LYVE-1+ flaps (blue) anchored by VE-cadherin (red), “buttoning” the cells together.

Sugar-coated leukocytes- by Louise Johnson

Super-resolution Airyscan confocal imaging of a human dendritic cell, with CD44 (green) and the glycosaminoglycan hyaluronan (red) at the cell surface, detected by antibody and biotinylated hyaluronan binding probe VG-1 respectively, and nucleus counterstained with DAPI.

Myelofibrosis Analysis by Guanlin Wang

The image shows over 130k cells of human HSPCs from both healthy individuals and myelofibrosis patients. Each dot is a single cell and the colour refers to different lineages. Large expanded purple  ‘tails’ are the cancer cells in myelofibrosis patients.

3D rendering of vascularised hydrogel - by Abdullah Khan

Generating artificial vasculature is an area of significant interest in the tissue engineering field. The production of branching networks supported by pericytes in a 3D mixed matrix hydrogel is imaged here.

Zebrafish embryo wrapped around its yolk - by Martyna Lukoseviviute

A ventral view of a 14 somite stage zebrafish embryo, head to tail. Hybridisation chain reaction was used to simultaneously stain transcripts of two soxtranscription factors involved in central nervous system development and a wnt gene coding for a signalling protein important for embryo patterning.

WIMM is the scientific wonderland, gives me a fantastic scientific journey.

Zebrafish neural crest development -by Martyna Lukoseviviute

A lateral view of a 14 somite stage zebrafish embryo, head to tail. Immunofluorescence staining was performed to visualise neural crest cells expressing different transcription factors.

Vascular Organoids- by Abdullah Khan

Induced pluripotent stem cells (iPSC) can be used to generate primitive ‘organoids’ which reproduce physiological structures, and allow us to more accurately study disease pathologies. Here, iPSCs are differentiated to mak a vascularised organoid which we use to study the effects of Covid19 on the microvasculature.

The queen ovary - by Martyna Lukoseviviute

The image displays an optical section of an ovariole (a serial unit of an ovary, female reproductive organ) of a honeybee queen pupae. Ovarioles were stained with phalloidin (in cyan) for filamentous cellular actin visualisation, cell membrane dye (in magenta) and cell nuclei (with DAPI in yellow).

iPSC-MK's forming proplatelets - by Abdullah Khan

Megakaryocytes are the rarest and largest cells of the bone marrow, responsible for the generation of blood platelets by making unique, long beaded extensions called pro platelets. Here we use Megakaryocytes derived from induced pluripotent stem cells to look at the effects of genetic mutations on pro platelet formation.

Zebrafish embryo- by Martyna Lukoseviviute

This is an image of the failed, but unexpectedly beautiful, experiment. A young zebrafish embryo (70% epiboly stage)  was unspecifically stained for three different fluorescently labelled transcripts using the hybridisation chain reaction technique. I like this image because it resembles an image of a planet.
