Abstract

fetched live from OpenAlex

Research in the model system Drosophila melanogaster has highlighted the importance of cell-specific in vivo omics analyses to study intestinal epithelial homeostasis. Here, we present an optimized protocol for profiling intestinal progenitor cells (PGs) at the transcriptome and lipidome levels. We describe steps to dissect midguts, isolate fluorescently labeled PGs using fluorescence-activated cell sorting (FACS), and obtain high-quality RNA for library preparation or total lipid extraction for untargeted lipidomics. This protocol yields high-quality transcriptomic and lipidomic data under various experimental conditions. For complete details on the use and execution of this protocol, please refer to Makdissi et al. 1

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
