Similar to osteocytes in vivo, these cells respond to hormonal signals such as PTH and 1,25-dihydroxyvitamin-D3. IDG-SW3 cells can be maintained in both 2D and 3D cultures and are useful for study of osteocytes at various differentiation stages. It should be noted that these cultures may contain a mixture of osteoblasts and osteocytes at different stages of differentiation and for studies requiring enriched osteocytes, the Dmp1-GFP cells should be isolated by flow cytometry (FACS).The presence and absence of SV40 large T-antigen under permissive and non-permissive conditions, were confirmed using western blot.
