Fig. 1From: Small blood stem cells for enhancing early osseointegration formation on dental implants: a human phase I safety studyPurification and characterization of SB cells from human peripheral blood. A SB cells were presented using the DAPI positive staining (red arrow). WBC, yellow arrow. Bar = 10 μm. B The ratio of CD61−Lin− cells in the SB mixture was analyzed by a flow cytometer. C The ratio of Lgr5+ cells in SB mixture or CD61−Lin− fraction was analyzed by a flow cytometer. D SB cell morphology was analyzed by TEM. Red dotted line, nucleus; Red arrow, mitochondria.
