Example 6

Round 3-D inserts (having three micro-channels of 3 mm width by 20 mm length by 10 mm height) were seeded with 10,000 P6 cells human bone marrow-derived mesenchymal stem cells (labeled with cell tracker red) per channel in 200 μl of culture media in a tissue culture dish on a rocking platform. Rocking frequency was 5 rpm and 15° tilt. After one-day culture, another 10,000 cells (labeled with cell tracker green) were added to the same channel and cultured for another day. FIGS. 8A and 8B show cell aggregates with two different colors after 2 days of cell culture.
