BMDCs do not differentiate into endothelial cells in ear punch wounds and decubitus ulcers. (A) The procedure for the ear punch wound model or the decubitus ulcer model combined with the GFP-bone marrow chimeric experiment. (B-S) Macroscopic views (hematoxylin and eosin staining) or sectional immunohistochemistry for indicated antibodies. Grids in panels D and M indicate the fields in panels F-J and panels O-S, respectively. GFP⁺ cells that accumulated in the granulation tissues are mostly F4/80⁺ macrophages (arrowheads). Bars represent 50 μm.
