Abstract

Abstract: Although document studies (including ours) have been reported the achieved in vitro osteoclastic cellular model establishment from the RAW264.7 cell lineage, there was no study directly reported that American Type Culture Collection (ATCC) cell bank has various RAW264.7 cell lineages. Besides that, for our knowledge there was only one study compared the two different RAW264.7 TIB‐71 and RAW264.7 CRL‐2278 cell lineages for their osteoclastic differentiation, and they concluded that the RAW264.7 CRL‐2278 demonstrated to generate much osteoclast than RAW264.7 TIB‐71 . However, on the contrary to their results we noticed the fusion of RAW264.7 TIB‐71 in our previous studies was much compromising. Therefore, we try to explore the two cell lineages for their properties in osteoclastic differentiation with an in‐depth cellular cytoskeletal study. Our current study has showed that comparing to the RAW264.7 CRL‐2278, RAW264.7 TIB‐71 demonstrated a much higher efficacies for RANKL‐stimulated osteoclastic differentiation. Besides that, in our depth cytoskeletal studies, we found that the RANKL‐induced RAW264.7 TIB‐71 cells could finally differentiate into mature osteoclasts. However, regardless the various pre‐treatment conditions, there was no mature osteoclast formed in RANKL‐induced RAW264.7 CRL‐2278 cell lineage.
