Figure 2. CRSwNP patients (n=13) with less systemic 25VD3 have increased proliferating HSNFs compared to control patients (n=6).

Figure 2

Proliferating HSNFs were identified ex vivo from sinonasal tissue biopsies via flow cytometry as cells that stained FSP+, Ki67+ and MUC1−. 25VD3 was measured in patient plasma at the time of surgery using commercially available ELISA. Each symbol represents an individual patient and statistics are the results of Pearson correlation. HSNF = human sinonasal fibroblast. CRSwNP = chronic rhinosinusitis with nasal polyps. 25VD3 = 25-hydroxy vitamin D3. ELISA = enzyme-linked immunosorbent assay.
