Well done to @elsieplace.bsky.social, Marysia Placzek and @sethblackshaw.bsky.social for this beautifully clear overview of a very complex history of brain developmental models www.sciencedirect.com/science/arti...

I illustrated my way through the @bsdb.bsky.social Spring Meeting a couple weeks ago - here's my illustrated summary of the conference! I sketched (almost) all the speakers and glimpses of the science that made it such a great few days.

#DBfeature 🧠 FGF10 operates with SHH and BMP to contribute to neurogenic and gliogenic fates in the puberal hypothalamus By K Chinnaiya, I Groves, E Manning, E Place, C Furley, SE Strawbridge, AG Fletcher, M Placzek tinyurl.com/muee82sm
Specification of tuberal neurogenic progenitors at early neural plate stages (A–I) Maximum intensity projections of hemi-views (A-C, D-H') or ventral view of isolated neuroectoderm (I) of HH6 (A-C, I) or HH17–18 (D–H') embryos after HCR. (A–C) Hemi-views labelled for SHH and NKX2-1 (A); SHH and PTCH1 (B); FOXG1 and BMP2 (C). White bracket marks HypFP cells. (D-E') Fate mapping of HypFP cells at HH6. (D) Mid-HypFP cells (dorsal view, inset in D) give rise to tuberal gliogenic cells, identified by their position relative to the mammillary pouch (mp arrowhead in D). (E) HH17 embryo after anterior-most HypFP cells labelled at HH6 with DiI, and HCR analysis. DiI is located in the SHH+ neurogenic hypothalamus, the SHH- gliogenic hypothalamus, but not the FOXG1+ telencephalon. Boxed regions in (F, G) shown at high power in (F′, G′). (H′) shows double channel view of FGF10 and FOXA2. Arrowhead points to mammillary pouch (mp) and optic stalk (os). (I) HH6 isolated neuroectoderm after HCR to detect SHH/PTCH1. White bracket marks HypFP cells; white lines represent positions of slices shown in I’. (I′) Explants of regions 1–4, after HCR to detect SHH/PTCH1 confirms accuracy of dissection. (J) Midline sub-dissection from a position 4 explant (yellow boxed region in I′), showing position of DiI-labelling (red circles). MIP shows SHH and PTCH1 are expressed through the explant at 0 h. (K–Q) MIPs of wholemount views of HH6 Hyp explants (regions 3 or 4 in (I′)), cultured for 72 h, then analysed by HCR (right hand panels show single or double channel views) showing expression of SHH/PTCH (L); NKX2-1/POMC/FOXA2 (M); SHH/PTCH1/NKX2-1 (N); ISL1/POMC (O); FGF10 (P); TBX2 (Q). Scale bar = 100 μM.

Looking forward to the #biologists100 conference in Liverpool next week! I’m creating a thread below to link to my poster (in collaboration with @elsieplace.bsky.social) so we can share our 4D model of forebrain development. Come visit us: Poster 200, Session 2 on Wednesday.

Exclusive: Trump plans to revoke legal status of Ukrainians who fled to US, sources say
U.S. President Donald Trump's administration is planning to revoke temporary legal status for some 240,000 Ukrainians who fled the conflict with Russia, a senior Trump official and three sources familiar with the matter said, potentially putting them on a fast-track to deportation.

New! 15y after the classic Aigouy et al "Cell Flow Reorients the Axis of Planar Polarity in the Wing Epithelium..." from lab of much missed Suzanne Eaton, we provide our take from post-doc Sara Tan "Tissue shear as a cue for aligning planar polarity in the developing Drosophila wing". rdcu.be/d81Vn
Planar polarity in the Drosophila pupal wing is oriented by tissue stress but the mechanisms remain unclear. This study uncovers a crucial role for cell flow gradients in promoting planar polarity protein turnover and aligning proximodistal polarity.

Check out our fabulous 4D model of forebrain development, created in Blender from imported light sheet scans of HH10-20 dissected chick neuroepithelium, and painstakingly linked together by @elsieplace.bsky.social by combining published fate maps with 100's of our own samples.

Excited to present our new preprint clarifying forebrain developmental organisation. Complex growth patterns shape the forebrain but distort the A-P + D-V axes, hence prior confusion over brain layout.

We begin the New Year with two preprints on hypothalamic development. The first, part of a long-term collaboration with Marysia Placzek’s group, investigates the organization of the developing forebrain, and show that current models are (mostly) incorrect./1 www.biorxiv.org/content/10.1...
