Concentration dependence of HMEC-1 capillary tube inhibition by factor XIIIa in γA/γA and γA/γ′ fibrin.

The number of sprouts per microcarrier for HMEC-1 cells in γA/γA (filled circles) or γA/γ′ fibrin (open circles) was determined. Cell sprouts were defined as projections containing a minimum of 3 nuclei. Each point represents the mean of triplicate determinations ± SD.
