A laparoscopic biopsy is done by making a small incision in the abdominal area through which a tube-like instrument is inserted to collect the sample. Reticulin staining is performed to detect reticulin fibres and assess body cells (from liver, kidney, spleen) for conditions such as necrosis (unplanned death of the cells constituting a tissue), and hyperplasia (increase in size of tissue due to excessive cell division). Translational research projects are as novel as the technologies that drive them. The process involves the following steps: The Wright and Wright Giemsa stains are polychromatic stains because they contain eosin and methylene blue. 1.
