Abstract:
:Multipotent skin-derived progenitors (SKPs) can be traced back to embryonic neural crest cells and are able to differentiate into both neural and mesodermal progeny in vitro. Neural stem cells (NSCs) are capable of self-renewing and can contribute to neuron and glia in the nervous system. Recently, we derived porcine SKPs and NSCs from the same enhanced green fluorescent protein (EGFP) transgenic fetuses and demonstrated that SKPs could contribute to neural and mesodermal lineages in vivo. However, it remains unclear whether porcine SKPs and NSCs can generate ectoderm and mesoderm lineages or other germ layers in vivo. Embryonic chimeras are a well-established tool for investigating cell lineage determination and cell potency through normal embryonic development. Thus, the purpose of this study was to investigate the in vivo developmental potential of porcine SKPs and fetal brain-derived NSCs by chimera production. Porcine SKPs, NSCs, and fibroblasts were injected into precompact in vitro fertilized embryos (IVF) and then transferred into corresponding surrogates 24 h postinjection. We found that porcine SKPs could incorporate into the early embryos and contribute to various somatic tissues of the 3 germ layers in postnatal chimera, and especially have an endodermal potency. However, this developmental potential is compromised when they differentiate into fibroblasts. In addition, porcine NSCs fail to incorporate into host embryos and contribute to chimeric piglets. Therefore, neural crest-derived SKPs may represent a more primitive state than their counterpart neural stem cells in terms of their contributions to multiple cell lineages.
