In histological examinations, the hypodermis is typically observed using various staining techniques: 1. Hematoxylin and Eosin (H&E) Staining: This is the most common method, which stains the adipocytes pink and the connective tissue fibers blue. 2. Oil Red O Staining: This is used to identify lipids within adipocytes, staining them red. 3. Immunohistochemistry: This technique is employed to detect specific proteins and markers within the hypodermis.
