Morphology, attachment and proliferation of human neural stem/progenitor cells cultured on substrates coated with lam-IKVAV peptides, short IKVAV peptides, and whole LN. (A): Human neural stem/progenitor cells were stained with phalloidin (red). Scale bars = 100 μm. (B): Quantification of cell attachment and proliferation. Cells were assayed with CyQuant proliferation kit. A greater number of cells attached on cover slips conjugated with short IKVAV peptide than lam-IKVAV peptide at day 1 (inserted, ∗, p < .05). Abbreviations: IKVAV, Ile-Lys-Val-Ala-Val sequence; Lam-IKVAV, Cys-Ser-Arg-Ala-Arg-Lys-Gln-Ala-Ala-Ser-Ile-Lys-Val-Ala-Val-Ser-Ala-Asp-Arg sequence; LN, laminin.
