Organization and Matrix


Key concept

The embryonic dermis consists of a syncytium of interconnected cells suspended in a watery matrix of hyaluronic acid. The cells differentiate into fibroblasts which replace the primordial dermis with a cell-poor dense fibrous matrix of collagen, elastin, and dermatan sulfate. The fibrillar components of the dermis continue to develop well after birth.
