'Warhol wannabe?'

Arrayed confocal images display a binary

stem-cell based model recapitulating

primate amnion and embryonic disc segregation.

Nuclei are stained with DAPI and the apical

domain is marked with Par6. Spheroids present

two distinct morphologies that correspond to

the postimplantation epiblast - columnar

epithelium - and the amniotic ectoderm

– squamous epithelium. Both types of s

tructure are featured repetitively

to illustrate the high-throughput potential of in

vitro modelling of development.

'Sterlet immuno'

Sterlet (Acipenser ruthenus) larvae in two

different stages, stained using enzymatic

metallography with anti-Sox2 antibody to show

lateral line organs and taste buds (left) and

anti-acetylated Tubulin antibody to

show cranial nerves (right).

'Zombie growth cone looking for brains'


A Scanning Electron Microscope (SEM) image of

the growth cone, the tip of a growing axon,

cultured on glass. The preparation has caused

the plasma membrane of half of the growth cone

to be ripped off, revealing the cytoskeleton underneath.

'The abyss stares back'

Mosaically labelled cells in the periphery of MDCK

epithelial cell colony. As cells undergo

epithelial-to-mesenchymal transition (EMT), they

become more spread and motile. The image is

a colour-coded temporal projection of a movie

of EMT (actin shown in cyan to red between

0 h and 8 h after EMT induction).

The image shows an arrangement different

live frog (Xenopus) embryos injected with

fluorescent molecules to label specific tissues.

'A lightning storm in the

arcuate kisspeptin network'

Arcuate kisspeptin

neurons synchronise intermittently

to drive pulsatile hormone release for

the maintenance of fertility.

Here we see these cells synchronising within

an in vitro brain slice.

'Actin and myosin in cell division'


Live TIRF timelapse images of a HeLa cell

undergoing mitosis: only the surface of

the cell in contact with the coverslip is shown,

with actin filaments in magenta and

non-muscle myosin IIA in green.

The mitotic cell is round and anchored to the

glass with retraction fibres; after cytokinesis,

the two daughter cells spread out into angular

'How the brain associates

memories of events that are

separated in time'

This is a video abstract of our recently

published paper in elife 'Postsynaptic

burst reactivation of hippocampal

neurons enables associative plasticity

of temporally discontiguous inputs'

'Unsquished Squash'

A representation of myosin (Sqhash-mCh) during

germband extension in the Drosophila embryo.

The colours indicate the depth of the myosin in

the z-stack. Taken using the lattice lightsheet,

with help from Martin, with further processing in Fiji.
