hKLK1-MSC transfer reduced renal macrophage and T-lymphocyte infiltration.

<p>Immunohistochemical staining on formalin-fixed, paraffin-embedded kidney tissue sections. Kidney sections from <i>B6.Sle1.Sle3</i> mice treated with PBS (A, E), vector-MSCs (B, F) or hKLK1-MSCs (C, G) were stained with macrophage specific anti-Iba1 antibody (1∶800 dilution), or T-lymphocyte specific anti-CD3 antibody (1∶300 dilution). D and H are the percentage of Iba1 positive cells (D) and CD3 positive cells (H). Data shown are representative of 6 mice in each group (Original magnification 400×).
