Metformin does not block entry of gentamicin into OHCs in organ culture.

Fluorescently tagged gentamicin (3.5 μM for 24 hours) was used to investigate the entry of gentamicin into explants. Metformin (15 μM) did not block uptake of gentamicin into OHCs (n = 3). Green: Alexa Fluor 488 phalloidin, Red: GTTR. Scale bar = 10 μm.
