aExperiments were repeated three times with similar results; this table presents the result of one experiment.

b DiIhigh cells were isolated using DiI-based fluorescence-activated cell sorting.

c, dThe t-test was carried out to determine the difference between the two groups in three experiments: cP < 0.01; dP < 0.05,).
