PKH67-labeled hPD-MSCs were detected in the interstitium and near the follicular region in the ovaries after therapy. a PKH67-labeled hPD-MSCs showed green fluorescence. The scale bars indicate 200 μm. b PKH67-labeled hPD-MSCs (green) were observed in ovaries 1 week (b1–b3), 2 weeks (d1–d3), 3 weeks (f1–f3), and 5 weeks (h1–h3) after multiple-injection hPD-MSC therapy. Note the appearance of numerous PKH67-labeled hPD-MSCs in the interstitium of ovaries and some PKH67-labeled hPD-MSCs in the ovaries near the follicular region (white arrowheads). DNA was counterstained with DAPI (blue). Control, PBS-injected group; hPD-MSCs, PKH67-labeled multiple-injection hPD-MSC group. The scale bars indicate 200 μm
