Iron‐Based Metal‐Organic Framework MIL‐100(Fe) Regulates Keloid Scarring in a Humanized Keloid Model
The study shows iron‑based metal‑organic framework MIL‑100(Fe) nanoparticles are highly biocompatible, rapidly taken up by keloid fibroblasts, and selectively inhibit the TGF‑β/SMAD pathway, reducing collagen I, collagen III, and P4HA1 expression.
