“…Pulp stem cells are thus enriched on their ability to form colonies (Gronthos et al, 2000), their expression of cell surface molecules such as STRO-1 (Gronthos et al, 2000), or CD34 (Laino et al, 2006) or on their capacity of exclusion of a DNA binding dye (Iohara et al, 2006). Not surprisingly, the resulting different cell populations display various differentiation potentials, upon appropriate in vitro induction (for review see Huang, 2009) and are able to participate in bone (d 'Aquino et al, 2009;Seo et al, 2008), neuronal (Arthur et al, 2008 and corneal tissue formation in vivo (Table 3; Gomes et al, 2010). In an implanted tooth slice model, heterogeneous populations of DPSCs, SCAPs or SHEDs have already shown their capacity to participate in the formation of a pulp-like tissue with dentin secretion and apposition (Huang et al, 2010;Sakai et al, 2010).…”
