aristaless-like homeobox-3 is wound induced in muscle and stem cells and is required for planarian head regeneration

To investigate the role of alx-3 in activating wound-induced transciptional programs during anterior regneneraiton, control(RNAi) and alx-3(RNAi) planarians were amputated below the pharynx and were allowed to regenerate for 0.5 hours post-amputation (HPA), 6HPA, 24HPA, 48HPA and 72HPA. Intact animals were are also included.Tissue from tail fragments and intact animals was collected at each time point for RNA extraction and cDNA synthesis. Gene expression profiling analysis was performed using data obtained from RNA-seq of planarian tissues at 5 timepoints after regeneraiton and in uninjured animals . control(RNAi) and alx-3(RNAi) planarians were amputated below the pharynx and were allowed to regenerate for 0.5 hours post-amputation (HPA), 6HPA, 24HPA, 48HPA and 72HPA. Intact animals were are also included.Tissue from tail fragments and intact animals was collected at each time point for RNA extraction and cDNA synthesis.
