Figure 8. Down-regulation of PCNA protein
by siRNA in PFC in vitro and in vivo. Immunofluorescence staining
indicated the expression of PCNA decreased in PFC and NFC transfection
with Skp2 siRNA (C, F) when compared with hPFC
and hNFC transfection with pSuppressor vehicle (A, D) or
without transfection (B, E). The scale bar is equal to
40 μm.
