Abstract:
Objective:To clone and sequence cDNA of MH2 domain of Smad1 gene from human dental papilla cells. Methods:Total RNA was isolated from primarily cultured human dental papilla cells and reversely transcribed into single stranded cDNA.The desired DNA product was obtained by PCR with two gene specific primers.The segment was inserted into PUC19 vector and the plasmid was transformed into E.coli JM109.The double stranded cDNA of positive clone was sequenced.Results:The sequence of MHz domain of Smad1 cloned from human dental papilla cells was consistent with that reported by Hoodless et al. Conclusion:Smad1 exists in human dental papilla cells,BMP signaling may be mediated by smad1 in human dental papilla cells.
