'Sun and sea in the olfactory bulb'
An immunohistochemistry staining of
the principal cells and interneurons of
the murine olfactory bulb.
'Dividing zebrafish enveloping layer cell'
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 (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).
'Tribolium myosin embryogenesis'
'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).
'Lets light it up!'
The image shows an arrangement different
live frog (Xenopus) embryos injected with
fluorescent molecules to label specific tissues.
'Doming in epithelial tissues'
MDCK cysts stained for e-cadherin, actin, nuclei.
'A lightning storm in the
arcuate kisspeptin network'
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.
'Migration during avian gastrulation'
'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

'Crystal cells bursting in
'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'
'A closer look: 3D reconstruction
of wild type and knockout
3D reconstructions produced by
segmenting volume electron
microscopy (FIB SEM) images of
wild type and knock out murine
efferent ductules made to study
the role of primary ciliated cells in
the acquisition of male fertility.
'Build a Brain'
Timelapse of neural tube inflating
with fluid and opening in the
hindbrain region of the Zebrafish
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.
