Proliferation studies of Lyve-1⁺ cells with Ki-67 antibodies in ED 12.5 and ED 13.5 mice. For each ED, at least 5 sections of at least 3 mice were evaluated. The total number of cells counted was: 197 in lymph sacs (LS) on ED 12.5; 406 in lymph sacs (LS) on ED 13.5; 45 in sprouts from lymph sacs (Sp) on ED 12.5; 75 in sprouts from lymph sacs (Sp) on ED 13.5; 43 in scattered cells in the dermatomes (D) on ED 12.5 and 40 in scattered cells in the dermatomes (D) on ED13.5. Mean and standard deviation are shown. The value for D 12.5 is significantly higher than all others.
