β-ARNT and control mice graft insulin content and β–cell volume (in 1∶1 transplant model).

<p>(<b>A</b>) There was no significant difference in total insulin content between β-ARNT and floxed control islets one week post-transplantation (n = 6 per group). (<b>B</b>) The β-cell volume was not significantly different between the control and β-ARNT transplants (n = 6 per group). Data are presented as means ± SEMs. (<b>C</b>) Representative photomicrographs of kidney graft sections from control recipients and β-ARNT recipients (n = 4 mice/group). Brown coloration indicates insulin producing β-cells and blue is the haematoxylin counter stain.
