Non-cultured adipose tissue-derived human pericytes (ncATPCs) exhibit a distinctive gene expression signature.
ncATPCs express key adipose tissue stem cell genes previously described in vivo in mice.
ncATPCs express message for anti-proliferative and antiangiogenic molecules.
Most ncATPC-specific transcripts are absent in culture-expanded pericytes or ATMSCs
Gene expression changes ncATPCs undergo as they acquire a cultured ATMSC phenotype are pointed out.
