The traits of dedifferentiation and redifferentiation of the explants form H. sampsonii show that the calli the stem and leaf usually form buds at its parietal cells. In the presence of auxin, the parenchyma of the leaf gap at the node is initiated firstly, then, develops blastemata that form buds in a cluster on the node without callus. These show that the various parts ofthe herb differ greatly in cell initiation and organ differentiation.

研究元宝草外植体的脱分化和再分化的特点结果表明，茎段和叶片启动形成愈伤组织，其不定芽通常发生在愈伤组织的周边区，茎节叶腋的叶隙薄壁组织在激素的诱导下启动、分裂，不形成愈伤组织而直接器官分化成芽原基，并在节结处产生一圈成簇的不定芽，表明元宝草不同部位的细胞启动及器官分化调控存在差异。
