Semiquantitative overview representing the presence of stem cells (SV40+), leucocytes (CD45+), macrophages (CD68+) and neutrophils (MPO+) in ligated and non-ligated submandibular glands following intravenous and intraglandular stem cell injections. 0, no cell; +, less than 10 cells; ++, 10-30 cells; +++, more than 30 cells.
