Recent findings identify key cellular and molecular principles underlying these feats. The majority of current planarian experiments consist of inhibiting or silencing the expression of a protein encoded by a specific gene through pharmacology or RNA interference RNAi and using the results to determine the regeneration mechanism in which that gene is involved. It supports viewing of the video Identifying Key Genes in Regeneration. Chemicals temperature and seasonal factors can influence planarian regeneration. When a brown planarians body part is lost or damaged the planarian will regenerate a new body part to replace the lost one. We kept it in a small container and observed it regenerate.
