CD4 + T cell immunohistochemical staining. CD4 + T cell immunohistochemical staining in control (Group A) and double injection groups (Group D). Immunohistochemical staining showed that a larger number of CD4+ T cells had infiltrated control group allografts (a), whereas there were almost no T cells in MSCs-treated grafts (b). No secondary antibody immunohistochemical staining of Group A (c) and Group D (d). ***p < 0.001
