Examples of differential vessel growth between B6 and MRL mice. (a) Representative 20×images of B6 (right) and MRL (left) skin biopsies grown for 7 days using the ex vivo skin assay. (b) Average angiogenic responses of different inbred mouse strains. Four inbred strains (n=13/strain) were quantified as described in the accompanying text and the average cell number growing from each strain were compared. There was a greater than threefold difference in the total cell number between B6 and MRL after 7 days of culture.
