Farrukh et al. investigated a polylysine (PL) hydrogel matrix and a 19-mer peptide containing the laminin motif IKVAV (IKVAV) on neuronal progenitor cells under different stiffness regimes (2 and 20 kPa) (Farrukh et al., 2017), whereas Balion et al. investigated synthetic hydrogel matrices of polyethylene glycol (PEG) functionalized with collagen-like peptide (CLP) alone or conjugated with either cell adhesion peptide RGD motif (mimicking fibronectin) or IKVAV motif (mimicking laminin) and their impact on cancer cell migration (Balion et al., 2020). Here, LAMB2 is linked to cancer.
