  1. aExperiments were repeated three times with similar results; this table presents the result of one experiment.
  2. b DiIhigh cells were isolated using DiI-based fluorescence-activated cell sorting.
  3. c, dThe t-test was carried out to determine the difference between the two groups in three experiments: c P < 0.01; d P < 0.05,).
