Controlling stem cell differentiation is a longstanding goal in biomedical research. Here we explore how cell fate is influenced by RNA condensates, specifically P-bodies, which modulate gene expression posttranscriptionally. We profiled the transcriptomes of biomolecular condensates in diverse developmental contexts spanning multiple vertebrate species. Our analyses revealed conserved, cell type-specific sequestration of untranslated RNAs encoding cell fate regulators. P-body RNA contents do not reflect active gene expression in each cell type but are enriched for translationally repressed transcripts characteristic of the preceding developmental stage. Mechanistically, P-body contents are controlled by microRNAs and can be profoundly reshaped by perturbing AGO2 or …

Stem cell niches are essential for regulating stem cell self-renewal and differentiation during tissue repair and regeneration. However, the mechanisms supporting stem cell function in highly regenerative organisms, such as the freshwater planarian Schmidtea mediterranea, remain unclear. Using spatial transcriptomics, we identified two cell types associated with planarian stem cells: secretory cells we term "hecatonoblasts" and intestinal cells. Surprisingly, while hecatonoblasts were in close physical proximity to stem cells in the mesenchyme, they were dispensable for regeneration. In contrast, intestinal cells, despite lacking direct contact with stem cells, regulated both their position and function during regeneration. Electron microscopy revealed diverse …

Objectives: Congenital diaphragmatic hernia (CDH) often coexists with fetal growth restriction (FGR). The observed-to-expected (O/E) total fetal lung volume (TFLV) is used to assess CDH severity, predict outcomes, and direct fetal interventions. Expected TFLV measurements traditionally rely only on gestation age (GA). This simulation assesses how incorporating weight-adjusted GA norms affects O/E TFLV calculations in patients with isolated CDH and FGR.

Methods: A simulated dataset (n=1,005) utilized published mean fetal weight and TFLV references. Computer-generated variables included observed weights (3rd-10th %ile), O/E TFLV (10-65 %), and percent liver herniation (0-42 %). GA estimates were corrected by weight and used to …
