Tissue Microarray: An Emerging Potential Research Tool

Rationalisation of biomarkers using the conventional histopathological procedure is time consuming, laborious and pricey especially, when several markers are to be tested on various specimens. So, TMA is expected to surmount these substantial problems [3]. Tissue microarrays are produced by harvesting cylindrical tissue cores from different paraffin donor blocks and re-embedding them in an array on a single recipient paraffin block such that multiple specimens can be analyzed at the same time thus, conserving resources by analysis of smallcore biopsies of blocks rather than complete sections [1,4].
