Nevertheless, it has been shown that vessels of tumours transplanted into VDR KO mice have less pericytes coverage compared with those in WT mice, suggesting that pericyte attachment might be partially dependent on VDR.212 In contrast, the endothelial cell/pericyte ratio was reduced in full retinal mounts of VDR KO mice compared with those of WT mice.213. Here, VDR is linked to neoplasm.
