Assessment of the Protective Role of Prenatal Zinc versus Insulin Supplementation on Fetal Cardiac Damage Induced by Maternal Diabetes in Rat Using Caspase-3 and KI67 Immunohistochemical Stains

<div>A photomicrograph of KI67 immunohistochemical staining (×400) sections in the fetal myocardium. (a) Control group showing dense positive brown nuclear immunohistochemical staining with KI67. (b) STZ-induced DM group showing negative nuclear immunohistochemical staining with KI67. (c) STZ-induced DM treated with zinc group showing moderate positive nuclear immunohistochemical staining with KI67. (d) STZ-induced DM treated with insulin group showing minimal positive nuclear immunohistochemical staining with KI67.</div>
