Intestinal ulcers from biopsy-wounded wild-type and Bmp4-overexpressing mice

We performed RNAseq on ulcers and distant normal tissue from biopsy-wounded wild-type and Bmp4-overexpressing (Vil1-Cre;Rosa26-Bmp4) mice to investigate differences in gene expression between tissue states and genotypes. Biopsy wounding was performed by taking three biopsies from well-separated areas in the colon wall using forceps. Small tissue pieces were excised from the ulcers and distant normal colon tissue and collected for RNA sequencing.
