Abstract
OCHOA, C et al. Cell Cultures of the Sciatic Nerve and Dorsal Root Ganglia from Adult Mouse. Acta biol.Colomb. [online]. 2010, vol.15, n.1, pp.63-86. ISSN 0120-548X.
The Schwann cells (SC) are glial of system peripheral nerve. The nervous prostheses are related to the production of autologous SC obtained from the peripheral nervous and from the dorsal root ganglia (DRG). There is a small amount of literature that reports perineural cells (PC) and endoneural fibroblast (EF) cultures as elements to take account of prostheses. In this work, the micro dissection importance is described in the sciatic nerve (SN) and in the DRG to achieve SC, EF and PC culture with a purity of 98%. The SC grows up on different supports with and without mitogens. An elevated percentage of SC was obtained when the epineurium and the perineurium were removed in the SN (90%±3) and in the GRD (94%±3) before the enzymatic dissociation compared to seventy percentage when the micro dissection was omitted or eighty percentage without the epineurium micro dissection. The EF was adhered in the first twenty four hours and the twenty percentage of serum improved their growth. In the first passage, there is 99 percentage SC or EF, and they get the confluence in the six and eight day, respectively. The PC or the cells of the DRG don´t have neither a good dissociation, nor a growth in subcultures, they only grow from the perineurium explants that forms a lamina of several cellular layers more than a monolayer. In conclusion, the DRG and SN micro dissection and dissociated are indispensable to acquire in few days SC, EF and PC cultures with a high purity from adult animals.
