The control groups (a and c): no MTA coating on the bottom of the wells. The experimental groups (b and d): MTA coating on the bottom of the wells. The SHEDs cells were seeded on the square cover glasses. In the direct contact (DC) groups (a and b), the surface of square glass with seeded cells faced downward and toward the bottom of the well. In the indirect contact (IDC) groups (c and d), the surface of square glass with seeded cells faced upward
