Necroptosis in primate luteolysis: a role for ceramide

Immunohistochemical staining of pMLKL(T357/S358) in CL from different species. The upper panels depict macaque CL in early-luteal (3？day old, a) and mid-luteal phase (7？day old, b) as well as during regression (14 days old, c). Lower panels show pMLKL(T357/S358) staining of large luteal cells in sections of human (d) and marmoset (f) CL. Corresponding pre-absorption controls are shown (e, g). Scale bars: 50？μm. Representative images are show
