Fig. 4From: A possible injectable tissue engineered nucleus pulposus constructed with platelet-rich plasma and ADSCs in vitroBrdU immumofluorescence staining. A large number of green fluorescent cell nucleus demonstrated the ADSCs can survive and proliferate in the PRP gel scaffold (8 weeks), × 400. The same view of DAPI restaining revealed the blue fluorescent cell nucleus, × 400Back to article page
