| Abstract: | A series of human tissue samples and cultured cell lines were formalin-fixed and paraffin-embedded. Specimen cylinder ( 1.2 - 1.8mm) 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. |
