Fig. 1. Plating efficiencies/colony forming efficiencies of bone and non-bone colonies in controls (Co), master dishes (M) and replica cloths (R) under different replication conditions. Bars are means and standard deviations of colony counts from a range of 4-34,100 mm dishes depending on the condition. The days indicated correspond to when the replica cloths were placed over/removed from the colonies in master dishes as described in Materials and Methods.
