Specimen cylinder （1.2 -1.8ram） were punched by a modified bone marrow biopsy needle and arrayed on a recipient paraffin block. Microscopic analysis on the sections from this tissue microarray （ TMA ） block demonstrated that the spots of tissues and cells were well preserved, and the cultured cell samples were successfully embedded from 5 × 104 to 2 × 105 in number. These TMA sections were also suitable for immunohistochemistry and RNA in situ hybridization.展开更多
