Human primary MSCs of different origins are permissive to KSHV infection. (A) Cellular morphology and GFP expression of MSCs following KSHV acute infection at different days postinfection. MSCa, human adipose tissue-derived MSCs; MSCbm, human bone marrow-derived MSCs; GMSC, human gingiva-derived MSCs; DPSC, human dental pulp-derived MSCs; SHED, human exfoliated deciduous tooth-derived MSCs. Magnification, ×100. (B) KSHV infection rates in different MSCs analyzed by flow cytometry based on GFP expression. The percentages of GFP-positive cells are indicated. (C) Cell proliferation of mock-infected and KSHV-infected MSCs.
