Mitochondria and Cristae Fusing Together (IMAGE) Nagoya University Caption Figure 2. In response to being deprived of nutrients, mitochondria fuse together and increase the number of cristae. (a) Frames from a time-lapse sequence showing two separate mitochondria fusing together to form a single mitochondrion. The outer membranes of the mitochondria are invisible: we are seeing the inner membranes fusing together. (b) Frames from a time-lapse sequence showing two cristae inside a single mitochondrion fusing together. (See Video 2 in the Supplementary Material on the paper's PNAS webpage.) The scale bars represent 2mm. Credit © ITbM, Nagoya University Usage Restrictions This image may only be used with appropriate caption or credit.
