Primary Schwann cells isolated from adult rat sciatic nerve and purified via magnetic activated cell sorting.
The culture of primary Schwann cells provides a unique in vitro system for basic research, preclinical drug discovery, neurotoxicity testing, and in vitro modeling of aging, cancer and disease conditions affecting the myelin sheaths. Schwann cell transplantation in experimental animals remains a promising strategy to investigate mechanisms of repair and myelination in the central and peripheral nervous system.

Schwann cells are obtained from the sciatic nerve of adult 3 month old rats using a novel protocol for immediate dissociation and purification by magnetic activated cell sorting (MACS). Schwann cells maintain their identity, viability and growth rates throughout the process of isolation, purification, expansion and cryopreservation. The cryopreserved product consists of MACS-purified rat Schwann cells identified as S100 positive, p75NGFR positive, GFAP positive cells. The absence of fibroblast contamination is determined on the basis of the lack of expression of Thy-1, a fibroblast-specific marker. These cells actively proliferate in response to defined mitogenic factors and increase the expression of myelination-associated genes in response to cAMP treatment, which are key indicators of preservation of biological activity.
Schwann cell cultures established from cryopreserved stocks are viable (>90% at 24 hs post-plating), expandable and homogeneous. Cells exhibit typical features of cultured Schwann cells including as ability to align to one another forming typical bundles of cells. Cells can be subcultured in media containing neuregulin and forskolin as mitogenic factors. NOTE: Excessive passaging is not recommended due to possible phenotypic derivation of the cells typically without transformation. Cells can be cryopreserved at essentially any passage.
