🚨In our new preprint we show that miRNAs act within a precise temporal window to control cell fate decisions in the human forebrain. 🧠 A study of miRNA expression dynamics and functions during early human brain development. @mdc-bimsb.bsky.social ‬ Check it out! www.biorxiv.org/content/10.6...

Post-transcriptional regulation of mRNA translation was explored using Ribo-STAMP and single-cell RNA sequencing to reveal cell-type-specific and isoform-specific translation patterns across hippocampal neuronal and non-neuronal cell types, highlighting functional differences between CA1 and CA3.

Had a great day at Human Technopole - lots of stimulating discussions with students and faculty and also, this should be a new standard, Aperol spritz after the seminar! @humantechnopole.bsky.social

We've spent the last year building something at @humantechnopole.bsky.social that we think is genuinely needed: #AI that works across biological scales and data modalities, not just within them. A thread on what we're doing, why, and who we're looking for. A 🧵... 1/9

MicroRNAs (miRNAs) are key post-transcriptional regulators of cell state transitions, yet their function in early human brain development is largely unknown. Here, we present a longitudinal analysis of miRNA function in developing human forebrain organoids. We show that mRNAs and miRNAs expression mirrors known developmental gene programs and that miRNA biogenesis peaks at neural commitment. To test the function of miRNAs in regulating commitment, we impaired their biogenesis at defined stages. miRNA disruption during pre-neuronal commitment caused severe patterning defects, whereas post-commitment perturbation had minimal impact on forebrain identity. We show that miRNA loss during pre-commitment increased WNT and BMP signaling, thus shifting cell fates towards non-forebrain identity such as midbrain/hindbrain. These effects could be partially rescued by expressing five miRNAs. Our findings uncover a critical time window where miRNAs regulate morphogen signaling in early human neurodevelopment, establishing them as essential temporal determinants of cell fate and brain regional identity. ### Competing Interest Statement The authors have declared no competing interest.
