  1. 1 number of concepti analyzed (<10% were damaged during dissection and were not included)
  2. 2 number of concepti containing beads at one or more sites
  3. 3 number of concepti with beads localized in target with few or no beads off-target
  4. * significantly different than EPC at E7.5
  5. EPC = ectoplacental cone region, AC = amniotic cavity, Exo = exocoelomic cavity, CI = confidence interval
