“…The most commonly used include Rgs5 (Bondjers et al, 2003), Pdgfrβ (Armulik et al, 2011), Nestin (Birbrair et al, 2013a), Tbx18 , CD146 (Dvoretskiy et al, 2019), and Neural/glial antigen 2 (Ng2) (Armulik et al, 2011). However, none of these markers are pericyte specific as each marker can identify multiple dermal cell populations; for example Pdgfrβ is also expressed by adventitial fibroblasts (Stapor et al, 2014) and CD146 is also expressed by endothelial cells (Crisan et al, 2008;Guerrero-Juarez et al, 2019;Gay et al, 2020;Haensel et al, 2020). Amongst the markers Ng2 is the most widely documented because it consistently labels cells with pericyte features on multiple types of vasculature in different organs (Ozerdem et al, 2001;Ozerdem and Stallcup, 2004).…”
