Establishment of rat bone mesenchymal stem cell lines stably expressing Chondromodulin I.

ABSTRACT: To study the role of Chondromodulin I (ChM-I) in inducing bone mesenchymal stem cells (MSCs) into chondrocytes, the plasmid expressing pcDNA3.1 (+) / ChM-I was constructed, and transfected into MSCs. Stable expression verified that ChM-I is upregulated in MSCs, which make it a useful preparation for studying the further role of ChM-I in inducing bone MSCs toward a chondrogenic I phenotype and for tissue engineering constructs. MSCs were obtained from adult Sprague Dawley (SD) rats using density gradient centrifugation. Cell surface antigens were detected by flow cytometry. The experimental groups were MSCs transfected with the plasmid pcDNA3.1 (+)/ChM-I. The control one was with the plasmid pcDNA3.1 (+) and the negative control one was with no plasmid. Transcription and translation were de
