Figure 2. LG histology in the control and aged groups. Control (A) and aged (B) samples stained with H&E (Scale bar=100 µm). Unstained samples of control (C) and aged (D), to demonstrate autofluorescence of LG (white arrows: lipofucsin-like deposits; Scale bar=100 µm). TEM (Scale bar=2.5 µm) of control (E) and aged (F) samples revealing details of LG acinar cells.
