Assessment of sodium iodide symporter (NIS) protein expression by Western blotting. Band densitometry confirmed that NIS expression was not significantly altered by the microfluidic culture of thyroid tumour tissue explants (n = 5). [+] and [−] represent protein extracted from tumour tissue with and without on-chip culture respectively. 1–5 indicates five separate patient samples and K1 is protein extracted from the thyroid cell line
