Adipose tissue                                       Chart


Cell types: Adipocyte (fat cell)
 

Differential diagnosis:
Other connective tissue types such as areolar tissue or dense tissue and also spongy bone. Adipose tissue presents with considerable vacuoles in fat cells which are not the feature of areolar tissue and dense tissues are thick and compact with parallel running fibers which are more in number than the cells. Spongy bone bone does not have criss-crossing network of yellow fibers.

Diagnostic Features:
a. Tissue is compact (e.g. liver)
b. Distinct cellular vacuoles which represent areas of dissolution of fat globules due to solvents used in preparation of tissues.
c. Nucleus is flattened and peripheral.
d. Presence of connective tissue septum which alone has parallel (or wavy) collagenous fibres.
e. It is found in subcutaneous regions having fat which are then called panniculus adiposus, in mesentery, kidney, omentum, bone marrow and synovial membrane.

Database selection: Practical Tissue Gross

Level 1: Select  compact
Level 2: Select connective tissue from list of sclerous, muscular, connective, organ-glands and nervous tissues since there is heterogenous collection of cells and fibers.
Level 3: Select spaces with the visibility of some thinness and spaces of tissue compactness. This will select both areolar and adipose tissues.
Level 4: Select nofibers and this will eliminate areolar tissue which has many fibers criss-crossing and parallel running..

Do you think this is a section of subcutaneous tissue or internal part of organ, or omentum or mesentery?
