This confirms, at a molecular level, the information obtained by cells also reduced the expression of stem cell osteogenic induction, CGF primaryARS experiments (Figure 8b). Following osteogenic induction, CGF main cells also reduced the expression of stem cell surface marker CD105 and CD45 by about 0.6- and 0.5-fold, respectively. markerCD105 and CD45 by about 0.6- and 0.5-fold, respectively.aCTROMb20 1.CTR OMmRNA fold changemRNA fold change15 ten 5 1 0.eight 0.six 0.4 0.2RUNXCOL1aOCNCDCDFiguremedium (Endoplasmic Reticulum To Nucleus Signaling 1 (ERN1/IRE1) Proteins Recombinant Proteins Control, CTR) or OsteogenicCGF principal Scale bar: 150 .
