1 Bone marrow-impregnated collagen matrix for wound healing: experimental evaluation in a microcirculatory model of angiogenesis, and clinical experience  Shigeru Ichioka, Sachio Kouraba, Naomoi Sekiya, Norihiko Ohura, Takashi Nakatsuka  British Journal of Plastic Surgery  Volume 58, Issue 8, Pages (December 2005) DOI: /j.bjps Copyright © 2005 The British Association of Plastic Surgeons Terms and Conditions

2 Figure 1 Appearance of the new chamber. The chamber consists of two aluminum frames held together by four polyethylene tubes. One frame is equipped with a plastic sheath and three small screws, and the other is furnished with a glass window for observation. (a) Aluminum frame. (b) Hole drilled for polyethylene tube to hold the two frames together. (c) Glass window for intravital microscopic observation. (d) Plastic sheath. (e) Fixing screw. (f) Plastic cap.

3 Figure 2 Skinfold chamber implantation. Transectional schema (above) and general appearance of a mouse with the chamber in place (below). The dorsal skin was drawn upward and a square area of one layer of skin has been removed. The frames were implanted so as to sandwich the stretched double layer of the skin between them. The remaining layer consists of skin (a) and a thin layer of striated skin muscle (b) covered with glass (c).

4 Figure 3 Wound creation procedure. Transectional schema (above) and appearance under an operating microscope (below). A circular area of skin was excised with microforceps and scissors down to, but not including, the underlying striated skin muscle layer. A dressing (a) covered the wound, and the plastic cap (b) fixed the dressing.

5 Figure 4 Intravital microscopic appearance of the whole window immediately after creation of the wound (left) and the magnified image of the wound with surrounding vessels designated as the region of interest (right). The wound (a) was located in the area supplied by the third order of arterioles (A3).

Photomicrographs (above) and the computer-processed binary images demarcating functional microvessels (below) on day 3 (A), day 5 (B), day 7 (C), and day 10 (D) after wounding.

(B) Appearance immediately after debridement and prior to application of bone marrow suspension (C) Good granulation tissue 2 weeks after bone marrow application. (D) Healed wound following treatment of bone marrow followed by a split-thickness mesh skin graft.
