Figure 5: Cellular uptake efficacy and intracellular localization of CPMSNs were observed by confocal laser scanning microscopy.

Figure (A) MDA-MB-231 and (B) MCF-7 cells treated with CPMSNs for various duration showed receptor mediated cell internalization of developed nanocarriers. The expression of integrin receptors on the cells was also demonstrated by (C) RT-PCR and (D) Western blot analysis. (E) The expression levels were also measured using densitometry profiles. Scale Bar 50 μm. *p ≤ 0.05.
