Project description:Lizards cannot naturally regenerate limbs but are the closest known relatives of mammals capable of epimorphic tail regrowth. However, the mechanisms regulating lizard blastema derivation and chondrogenesis remain unclear. We utilized single-cell RNA sequencing analyses of regenerating lizard tails throughout the course of regeneration to assess diversity and heterogeneity in regeneating tail cell populations.
Project description:Transcriptomic analysis of tail regeneration in the lizard Anolis carolinensis reveals activation of conserved vertebrate developmental and repair mechanisms
Project description:Transcriptomic analysis of scar-free wound healing during early stages of tail regeneration in the green anole lizard, Anolis carolinensis
Project description:Anolis carolinensis embryos were collected 0-1 days post egg laying, and total RNA was extracted for RNA-Seq analysis (Illumina Hi-Seq2000). Transcriptome sequence from these stages in the green anole, equivalent to mouse 9.5-10.5 dpc embryos, will help to improve gene annotations in A. carolinensis and provide expression level information for key organogenesis and patterning processes. Anolis carolinensis embryos were collected 0-1 days post egg laying for RNA-Seq analysis. The two embryos collected were at 28 somite-pair (28S) and 38 somite-pair (38S), equivalent to mouse 9.5 dpc and 10.5 dpc embryos, respectively. Total RNA was extracted using the total RNA component of the mirVana (Ambion) kit, RNA-Seq library prep was carried out using the NuGEN Ovation RNA-Seq kit, and sequencing was carried out on an Illumina HiSeq 2000, following the manufacturer's protocol. The untrimmed data was then aligned to the Anolis carolinensis reference genome (Anocar2.0) using tophat.
