Figure 6.
Ultrastructural and electrophysiological characteristics of the passaged iMGCs. (A) SEM images showed the iMGCs possessed a typical spindle-like morphology with many microvillus. (B) TEM images showed the iMGCs with abundant mitochondria (M), endoplasmic reticulum (ER), Golgi apparatus (G), glycogen (Gly), microtubules (MT), intermediate filaments (IF) and actins (A) in the cytoplasm. (C) Both P1 and P5 iMGCs depolarized after application of L-glutamate in current-clamp recordings. (D) P1 and P5 iMGCs presented no significant difference in resting membrane potential and the magnitude of depolarization. SEM, scanning electron microscope; TEM, transmission electron microscope; P1 and P5, passage 1 and 5; ns, no significance.
