  • Title: The phenotypic response of cultured quail trunk neural crest cells to a reconstituted basement membrane-like matrix is specific.
    Author: Maxwell GD, Forbes ME.
    Journal: Dev Biol; 1990 Sep; 141(1):233-7. PubMed ID: 1975242.
    Abstract:
    Previous work has demonstrated that a reconstituted basement membrane (RBM)-like matrix stimulates the development of catecholamine (CA)-containing cells in neural crest cultures. In the present work, we found that the proportion of tyrosine hydroxylase and somatostatin immunoreactive cells was increased substantially by an overlay of the RBM matrix. In contrast, there was little or no stimulation of the development of cells possessing several other phenotypic markers including A2B5, E/C8, vasoactive intestinal polypeptide, and the low and middle molecular weight avian neurofilament proteins. These results demonstrate that the response of neural crest cells to the RBM matrix is specific to a small set of phenotypes. In addition, we demonstrate that the phenotype of the adrenergic cells which develop in the presence of the RBM gel overlay is very similar, if not identical, to that of the adrenergic cells which differentiate in the absence of the RBM gel.
