Apical extracellular matrix development Read this Spotlight from our special issue #DevSIextracellular by Maxwell Heiman @heiman.bsky.social and Meera Sundaram @meera-sundaram.bsky.social. doi.org/10.1242/dev....
Composite figure showing the diversity of apical extracellular matrices (aECM) across animals. Arthropod examples include a butterfly wing and electron micrographs of butterfly scales, crab cuticle, and layered spider cuticle. Drosophila examples show sensory structures, olfactory nanopores, tracheal cuticle, and larval denticles. Vertebrate examples include crocodile scales, a bird feather, hamster zona pellucida fibrils, and cracked elephant skin, illustrating wide variation in aECM structure and function.

The array of organs in the animal body differ dramatically in their architecture, but cell-cell adhesion mediated by cadherins is a common principle. Our lab usually focuses on epithelia but cadherins are also active in migrating mesenchymal cells like these migrating testis myoblasts 1/n 🧪

New publication: Inner-Retinal Changes In AMD: Evidence, Mechanisms, and Future Perspectives. A fun project with Matt Trinh, Michael Kalloniatis, myself, Glenn Yiu, Enrico Borrelli, and Lisa Nivison-Smith bryanwjones.com/2026/03/inne...
Normal neuro-vascular maps of the macular inner-retina.
Top half clinical imaging: Topographic analyses from 96 normal eyes for OCT thickness (Trinh et al., 2022b) and 57 normal eyes for OCTA signal (Trinh et al., 2021a), with exclusion of any retinal macular/optic nerve pathology. Common locations of the optic nerve head and retinal blood vessels were excluded from OCT scans (Burke et al., 2024a, 2024b; Tong et al., 2020; Trinh et al., 2020, 2021b, 2022b). OCT layers are depicted on the left using a standardised thickness scale (darker green = greater thickness), while OCTA slabs are depicted on the right using a standardised OCTA signal (darker red = greater OCTA signal). Vascular slab approximations were adapted from Campbell et al. (Campbell et al., 2017). For reference, the RPE-BM (drusen layer) is shown using OCT thickness, and the choriocapillaris is shown using OCTA signal.
Bottom half histological imaging: Resin embedded, 100 nm serial section of mid-peripheral retina of aged, normal human eye (87 year old male) with amino acid immunolabelling of GABA, glycine, and glutamate mapped to the red, green, and blue colour channels, respectively, and rod opsin labelling indicated in yellow. The section illustrates the laminar organisation of the inner- and outer-retina for cross-reference with the OCT layers above and the distinct neurochemical signatures of neurons in these layers. White scale bar 100 μm.
RNFL, retinal nerve fibre layer; GCL, ganglion cell layer; IPL, inner plexiform layer; INL, inner nuclear layer; OPL, outer plexiform layer; ONL, outer nuclear layer; IS/OS, photoreceptor inner- and outer-segments; RPE-BM, retinal pigment epithelium to Bruch's membrane.

In their Review, John James, Darius Köster and colleagues consider E-cadherin-mediated cell-cell adhesion, focusing on recent advances in our understanding how actin cortex dynamics affect adherens junction stability. journals.biologists.com/jcs/article/...
AJs maintain tissue integrity by maturing in response to actomyosin generated tension at cell–cell contacts. (A) AJs are formed in the apical region of polarised epithelial tissues. Subsequent figures show a top-down view of an x-y plane at the apical region. (B) Schematic defining the key components involved in cell–cell adhesion, as discussed in this Review. Cadherin–catenin complexes (CCCs) hold together the actin cytoskeletons of adjacent cells at regions of cell–cell contact. Clustering of CCCs forms AJs. (C) Pulling forces exerted on CCCs changes their bio-mechanical properties. The E-cadherin trans interaction changes from an X- (left) to a strand-swap (right) conformation and α-catenin recruits vinculin, which strengthens the binding of α-catenin to F-actin. Florette indicate catch bonds, which increase in lifetime with applied force (E-cadherin X dimer, α-catenin tail domain–actin and vinculin tail domain–actin).
