I"m on holiday http://cliphunter.in.net/ www.pichunter.com Currently, the research has only used dental tissue obtained from mice, and grown the teeth in mice, and caution should be exercised when trying to generalise the findings from animal research to humans. Also, the experiments were not a complete success, as only a third developed into â?˜teethâ?™ and few had the hardness of human teeth. |
