Figure 7: Hematoxylin and eosin staining of osteoblast recellularized CS/nHAp-modified scaffold. Images at magnification 10x visualize the scaffold matrix after a successful 7-day recellularization of osteoblast cells. Nuclear counterstaining was detectable, identifying the cells growing inside the CS/nHAp-modified scaffold. Hematoxylin stains the nuclei of osteoblast cells blue, and the eosin stains the scaffold ECM structures pink. Arrows represent the osteoblast cells within the CS/nHAp-modified scaffold.
