Angiogenesis and the skin: a primer.
Angiogenesis is the development of a blood supply to a given area of tissue. This area of tissue may be part of normal embryonic development, revascularization of a wound bed, or the stimulation of vessel growth by inflammatory or malignant cells. Angiogenesis is of crucial importance to the dermatologist, as it is of key importance in pathologic processes such as psoriasis, warts, and cutaneous malignancy, and it is required for optimal wound healing. Other dermatologic processes wherein angiogenesis is defective or uncontrolled are decubitus ulcers, stasis ulcers, pyogenic granulomas, hemangiomas, Kaposi's sarcoma, and possibly Spitz nevus, hypertrophic scars, and keloids. Recent advances in the understanding of growth factors will likely lead to advances in the treatment of skin cancer and psoriasis, and more rapid healing of wounds. In this review, I hope to summarize the most important growth factors, inhibitors of angiogenesis, and future directions in research and therapeutics involving angiogenesis.
