Unformatted text preview: expansion of pre-existing ephrinB2-positive cells. When undifferentiated ECs were treated with higher concentrations of VEGF (25 and 250 pM) under the same conditions as above, there was no additional increase in the number of ephrinB2 positive cells beyond that achieved with 2.5 pM VEGF. What is a plausible explanation for this result? Only a limited percentage (~50%) of the undifferentiated ECs have functional receptor molecules in the PM capable of responding to expgenous VEGF....
