Detection of CD34+ cells in cutaneous wounds after 7 days of MSC implantation
IH studies to detect CD34+ were performed in untreated wounds (control, A), CM-treated wounds (B) and MSC/CM-treated wounds (C). Tissue sections show NS and NE in the edges of wounds (W). A larger number of CD34+ cells are observed in epidermis adjacent to the wound, NE, HFs (head arrow) and SGs (asterisks) in the group treated MSC/CM (C), as compared with the control and the group treated with CM (A,B, respectively). Scale bar = 50 μm.
