Osteocytes from B6 Col4a3−/−/DMP1TG and from DMP1-injected 129 Sv Col4a3−/− mice were elongated and comparable to WT osteocytes, suggesting that DMP1 fully corrected the alteration in osteocyte morphology induced by CKD (Fig. 3a). The gene discussed is COL4A3; the disease is chronic kidney disease.
