  • Title: Analysis of the development of cellular subsets present in the neural crest using cell sorting and cell culture.
    Author: Maxwell GD, Forbes ME, Christie DS.
    Journal: Neuron; 1988 Sep; 1(7):557-68. PubMed ID: 2483102.
    Abstract:
    We have tested the hypothesis that developmentally significant cellular subsets are present in the early stages of neural crest ontogenesis. Cultured quail trunk neural crest cells probed with the monoclonal antibodies HNK-1 and R24 exhibited heterogeneous staining patterns. Fluorescence-activated cell sorting was used to isolate the HNK-1+ and HNK-1- cell populations at 2 days in vitro. When these cell populations were cultured, the HNK-1+ sorted cells differentiated into melanocytes, unpigmented cells, and numerous catecholamine-positive (CA+) cells. In contrast, the HNK-1- sorted cells gave rise to melanocytes and unpigmented cells, but few, if any, CA+ cells. When neural crest cells at 2 days in vitro were labeled with R24 and sorted, both the R24+ the R24- sorted cell populations produced numerous CA+ cell, melanocytes, and unpigmented cells. These results provide evidence for the existence of developmental preferences in some subsets of neural crest cells early in embryogenesis.
