Hematomas adjacent to wounds in HB mice. HB mice developed hematomas (indicated by asterisks) in the subcutaneous tissues in the vicinity of the wound site (indicated by double-headed arrows). The left panel shows an example of a hematoma underlying the site of a 2-day-old wound. The right panel shows a completely healed 11-day wound, with a persistent hematoma in the subcutis. Original magnifications were × 40 (10 × ocular/4 × objective, NA = 0.13).
