Figure 4  Donor array, before and after tissue transfer, showing unimpaired remaining cores. (A) TMA performed with TMA-M (core diameter is 1 mm, and distance between cores is 0.5 mm); (B) TMA performed with TMA-GM (core diameter is 1 mm, and distance between cores is 0.7 mm); (C) TMA performed with old machine (core diameter is 0.6 mm, and distance between cores is 0.6 mm); and, (D) TMA performed with TMA‑GM (core diameter is 0.6 mm, and distance between cores is 0.6 mm).
