Tantalum Particles Induced Cytotoxic and Inflammatory Effects in Human Monocytes

Figure 4

Effects of Ta particle on apoptosis. (a) The number and density of THP-1 cells increased with culture time. (b) Necrotic cells accounted for a small proportion of the total cells. Normal living cells accounted for the main proportion in the three groups, and a small number of apoptotic cells were observed. For apoptotic cells, more cells were in the late stage than those the early stage. (c) The percentage of apoptotic cells increased gradually with different culture times.
