Figure 5: Phase contrast microscopic integrity of artificial cells seeds that were prepared with Sph-DNA from human placenta and F-fraction. Sph solution was added to the heated human placenta DNA solution. Then, F-fraction was added to the mixture. Seeds were examined under a phase contrast microscope. A single wad or aggregates, each aggregate like a clump of wads, were observed. Scale bar is 20 μm.
