Cell Morphology after NFC exposure. Morphology of HDF, MRC-5 and THP-1 macrophages after direct contact with NFC. Top images show HDF, MRC-5 and THP-1 cells untreated (negative control). For all other conditions, HDF, MRC-5 and THP-1 cells were treated with the highest concentration of U-NFC, A-NFC and C-NFC (500 μg/mL) for 24 h. Black arrows indicate agglomerates of fibres. Images of cells treated with the positive control (DMSO 5%) are given in Additional file 1: Figure S1. Scale bars represent 100 μm
