Isolation and culture of porcine primary fetal progenitors and neurons from the developing dorsal telencephalon

Research output: Contribution to journalJournal articleResearchpeer-review

The development of long-term surviving fetal cell cultures from primary cell tissue from the developing brain is important for facilitating studies investigating neural development and for modelling neural disorders and brain congenital defects. The field faces current challenges in co-culturing both progenitors and neurons long-term. Here, we culture for the first time, porcine fetal cells from the dorsal telencephalon at embryonic day (E) 50 and E60 in conditions that promoted both the survival of progenitor cells and young neurons. We applied a novel protocol designed to collect, isolate and promote survival of both progenitors and young neurons. Herein, we used a combination of low amount of fetal bovine serum, together with pro-survival factors, including basic fibroblast growth factor and retinoic acid, together with arabinofuranosylcytosine and could maintain progenitors and facilitate in vitro differentiation into calbindin 1+ neurons and reelin+ interneurons for a period of 7 days. Further improvements to the protocol that might extend the survival of the fetal primary neural cells would be beneficial. The development of new porcine fetal culture methods is of value for the field, given the pig's neuroanatomical and developmental similarities to the human brain.
