Striae: morphological aspects of connective tissue
Abstract:
The study of 15 abdominal striae in women aged 25 to 57 shows important histological modifications in the skin. The collagen is fragmented and the ground substance is abundant. Fibroblasts are globular, quiescent, and lose all signs of fibrillar secretion. In the light of the recent biochemical data, our results suggest that the striae are the consequence of fibroblastic dysfunction, due to abdominal distension. Comparison with scarred and normal skin indicate that striae are a special entity belonging to the group of connective dystrophies.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
