The role of the gene Mest during mouse digit tip regeneration


ABSTRACT: The distal mouse digit tip undergoes complex tissue regeneration following amputation, a process facilitated by the formation of a cellular structure called the blastema. Through single-cell RNA sequencing of the blastema, we identified the gene Mest (mesoderm specific transcript) highly expressed in a subset of blastemal fibroblasts. To determine if Mest expression is necessary for mouse digit tip regeneration, we analyzed Mest wildtype (WT) versus homozygous knockout (KO) post amputation digits. Through single-cell sequencing and FACS analysis of WT and KO regenerating tissues, we determined that this phenomenon was due to a prolonged immune response in the KO digits.
