Deciphering cell-type-and temporally specific matrisome expression signatures in human cortical development and neurodevelopmental disorders via scRNA-seq meta-analysis - Nature Communications
Human cortical development involves dynamic changes in matrisome gene expression across cell types and developmental stages. Here, authors show that these changes reveal links to neurodevelopmental di...

Our work out in @devbiol.bsky.social, PDGFra is needed for 🧠 perivascular fibroblast development... ⬇️ perivascular fibroblast = ⬇️ perivascular macrophage...cross-talk? 👀
Led by Hannah Jones @hejcell.bsky.social w/ Kelsey Abrams, Sophia Kim, excited for more projects w/ @fantauzzolab.bsky.social!

Thrilled to share this last little bit of my thesis work w/ @siegenthalerlab.bsky.social! 🐭🧠 Generating the PDGFRa cKO line we use in this paper was no trivial task, spanning multiple years (& a pandemic!) We were extremely excited to see this phenotype & even more excited to share it with everyone!

I learned so much at the @amsocmatbio.bsky.social meeting! I’m really grateful for the welcoming community, enthusiastic to offer advice and share protocols. They’re also actively building incredible public resources which lower the barrier to studying the matrix in your preexisting omics datasets.

Stoked to be repping the @korblab.bsky.social at #sfn25 this week! Come learn histone variant H2BE and its relevance to neurodevelopmental disorders on:

1. Saturday at the Early Career Session (#B1)

2. Monday at the Molecular Mechanisms Underlying Developmental Disorders II session (#A59)

Big advance from Lombroso et al. — microglia replacement without chemo, irradiation, or direct CNS delivery!

CSF1R inhibition + vascular delivery of Csf1r-G793A donor cells → specific brain engraftment. This study opens the door to microglia replacement across models & diseases.
📄🚨: Building off a stellar 2023 pub that engineered an hCSF1R variant, Sonia et al. now show how an mCSF1R variant not only confers inhibitor resistance and allows for efficient & non-toxic microglia replacement, but does so after vascular delivery into immunocompetent mice! 👏🧠

Last night I could not put this book down. The opening chapter is 🤯 and the final chapters full of great ideas about what we can collectively do to ensure women & underrepresented groups stay in science. We need diversity in science as diversity breeds discovery
