Test for longitudinal growth. Six scaffolds were tested over a 2-week period to see when MC3T3 cells reached an optimal confluency in the bovine trabecular bone scaffold. Results from 3 days to 7 days were optimal and seemed to decrease around 14 days but not to values that would be considered below a tolerable confluency for an experiment with the bioreactor.
