The Wnt/beta-catenin Master Switch, How a Face Cell Decides What NOT to Be
Take the reading one piece at a time. For each piece: read it once, underline the sentence that says what happens, then look up any word in the list. Tap a word to see its definition.
Piece 1 of 2
The Atit Lab at Case Western Reserve University, the lab partnering with John Hay Biomedical, can switch OFF Wnt signaling in cranial mesenchyme cells by deleting the gene that lets cells release Wnt.
Piece 2 of 2
With the Wnt/beta-catenin signal present (normal), bone and skin formed normally and almost no cartilage appeared. With the signal removed, bone and skin FAILED and ectopic cartilage appeared inside the future bone area. The cells did not just stop; they defaulted to cartilage in a place that should have been bone. The authors call cartilage a default state that Wnt signaling normally overrides (PMID:24586192; PMID:20980404).
Reading the Research
- Skim the title and abstract first to get the gist.
- Circle the one sentence that states the main claim.
- Box the evidence the authors give for that claim.
- Mark one sentence that confuses you, and move on.
Now put it together: In one or two sentences, say what this whole reading is telling you about Mateo. Then go back to the lesson and fill in the guided notes.
