# Citation Nebula Map — Stem Cell Secretome

> An interactive 3D visualisation of the stem cell secretome literature: real, curated papers
> rendered as a glowing citation nebula, grouped into eight disease clusters and connected by
> keyword co-occurrence / reference-overlap edges. Free of charge, no account required,
> runs entirely in the browser (WebGL via three.js).

## What it does

- Maps ~60 curated research papers on mesenchymal stem cell (MSC) secretome therapy
  across 8 clusters: General Secretome & EV · Osteoarthritis/Cartilage · Cardiac/MI ·
  COVID/Lung/ARDS · Neuro/SCI/Ocular · Liver/Hepatology · Kidney/Renal · Wound/Skin.
- Spatial distance approximates topical relatedness (force-directed layout);
  hovering highlights a cluster; clicking a paper opens its metadata with an abstract
  summary and a DOI link to the publisher.
- Export: "Bake Static JSON" downloads the current corpus + edge list as JSON;
  "Download Corpus (ZIP)" bundles corpus.json, edges.json and a README.
- Honest-data badge included: edges mix deterministic keyword overlap with random sampling;
  citation data is partially sparse.

## Key facts

- Audience: researchers, students, clinicians exploring regenerative-medicine literature.
- Price: free. No sign-up, no payments (see refund.html), no analytics.
- Privacy: one strictly necessary localStorage entry stores your consent choice
  (see privacy.html). First visit shows a consent gate (Terms acknowledgement, age 16+,
  cookie preference).
- Tech: static HTML + three.js 0.160.0 + JSZip from unpkg.com; no build step.
