Postmortem corneal tissue obtained from otherwise discarded material after keratoplasties is oftentimes the source of the cells for ex vivo research. Relatively easy to isolate and cultivate as well as inexpensive to culture, CSSCs now represent a well-described cell type with attributes of mesenchymal stem cells (MSCs). These include differentiation- and immunosuppressive potential, as well as a favorable capacity to expand in vitro. Here, we in detail describe two straightforward methods to isolate and establish CSSC cultures ex vivo.The neuregulins (Nrgs 1-4) are a family of signaling molecules that play diverse roles in the nervous system. Nrg1 has been implicated in the formation of synapses and in synaptic plasticity. Previous studies have shown Nrg1 can affect neurite outgrowth in several neuronal populations, while the role of Nrg2 and Nrg3 in this process has remained understudied. The Nrgs can bind and activate the ErbB4 receptor tyrosine kinase which is preferentially expressed in GABAergic interneurons in the rodent hippocampus and cerebral cortex. In the present study, we evaluated the effects of Nrgs 1, 2, and 3 on neurite outgrowth of dissociated rat cortical ErbB4-positive (+)/GABA+ interneurons in vitro. All three Nrgs were able to promote neurite outgrowth during the first 2 days in vitro, with increases detected for both the axon (116-120%) and other neurites (100-120%). Increases in the average number of primary and secondary neurites were also observed. Treatment with the Nrgs for an additional 3 days promoted an increase in axonal length (86-96%), with only minimal effects on the remaining neurites (8-13%). ErbB4 expression persisted throughout the d
