The alterations of mitochondria, lysosomes, and autolysosomes in osteoclast fission
(A) Representative MitoTracker and LysoTracker staining fluorescence images showing BMMs, fused osteoclasts, and osteoclasts undergoing fission (Mitochondria, green; lysosomes, red) (n = 5). Yellow arrowheads indicate that fluorescent signaling of MitoTracker and LysoTracker were merged in osteoclasts undergoing fission.
(B) Representative transmission electron microscope images showing BMMs, fused osteoclasts, and fission osteoclasts (n = 3). Red arrowheads indicate mitochondria. Yellow arrowheads indicate autolysosomes.
(C) Quantification of the proportion of the colocalization area to the total area in the image (n = 3).
(D) Quantification of mitochondria and autolysosomes by transmission electron microscope.
∗p < 0.05 by one-way ANOVA (C and D).
