Embryonic Dissociated Dorsal Root Ganglia (DRG) cultures are commonly used to study the role of novel molecular pathways or drugs in Schwann cell development and myelination. This study found that the transition from SCP to iSC occurs between the 5th and 7th day in culture, and immature Schwann cells can differentiate into myelinating Schwann cells as early as 4 days post the induction of myelination in cocultures. Furthermore, coculture-derived Schwann cell monocultures exhibit similar myelinating potential to cultures established from neonatal sciatic nerves, providing valuable insight for future studies on Schwann cell development and myelination.
Embryonic Dissociated Dorsal Root Ganglia (DRG) cultures are often used to investigate the role of novel molecular pathways or drugs in Schwann cell development and myelination. These cultures largely recapitulate the order of cellular and molecular events that occur in Schwann cells of embryonic nerves. However, the timing of Schwann cell developmental transitions, notably the transition from Schwann Cell Precursors (SCP) to immature Schwann cells (iSC) and then to myelinating Schwann cells, has not been estimated so far in this culture system. In this study, we determined the expression profiles of Schwann cell developmental genes during the first week of culture and then compared our data to the expression profiles of these genes in developing spinal nerves. This helped in identifying that SCP transition into iSC between the 5th and 7th day in vitro. Furthermore, we also investigated the transition of immature cells into pro-myelinating and myelinating Schwann cells upon the induction of myelination in vitro. Our results suggest that Schwann cell differentiation beyond the immature stage can be observed as early as 4 days post the induction of myelination in cocultures. Finally, we compared the myelinating potential of coculture-derived Schwann cell monocultures to cultures established from neonatal sciatic nerves and found that both these culture systems exhibit similar myelinating phenotypes. In effect, our results allow for a better understanding and interpretation of coculture experiments especially in studies that aim to elucidate the role of a novel actor in Schwann cell development and myelination.
