Abstract
Microscopic changes in the stroma of developing adipose tissues were studied. An organized arrangement of collagen fibers was associated with spindle-shaped cells with basophilic cytoplasm. An unorganized arrangement of collagen fibers was associated with cells of irregular shape, little cytoplasmic basophilia and a large pale-staining nucleus. Adipocyte development was apparent only in unorganized collagen fibers. The unorganized stroma was located near muscle-tendon junctions. Other aspects of muscle were surrounded by organized stroma. Physical interactions between expanding muscle and connective tissue cells may prevent or delay collagen maturation, resulting in a matrix suitable for adipocyte development.
