The Practical of Healing & Repair Third Year
Healing of inflammation often involves in growth of capillaries and fibroblasts. This forms granulation tissue. Here, an acute myocardial infarction is seen healing. There are numerous capillaries, and collagen is being laid down to form a scar. Non-infracted myocardium is present at the far left.At high magnification, granulation tissue has capillaries, fibroblasts, and a variable amount of inflammatory cells (mostly mononuclear)
A thin layer of epidermal reepithelialization and extensive granulation tissue formation in the dermis
.
Granulation tissue ( capillaries, fibroblasts & collagen fibers) formed at site of incised wound, the overlying epidermis heals by regeneration.
This is a healing biopsy site on the skin seen a week following the excision, The skin surface has re-epithelialized, and below this is granulation tissue with small capillaries and fibroblasts forming collagen
Excess collagen deposition in the skin forming a raised scar known as keloid (Hypertrophic scar)
The accumulation of excessive amounts of collagen in the dermis (keloid)
