Fig. 4From: Biological and microbiological interactions of Ti-35Nb-7Zr alloy and its basic elements on bone marrow stromal cells: good prospects for bone tissue engineeringDAPI coloration was observed on all samples. The graph shows the Nb group (c) with higher cell proliferation, while the Zr group (d) exhibited the lowest number of stained nuclei. No statistical difference between the groups: a titanium alloy, b pure titanium, c niobium, and d zirconiaBack to article page
