Preparation of Human Olfactory Ensheathing Cells for the Therapy of Spinal Cord Injuries.

We developed an optimal protocol for preparing and culturing of olfactory ensheathing cells from human olfactory mucosa. Using this protocol, we obtained a culture enriched with human olfactory ensheathing cells. Immunofluorescence analysis by simultaneous expression of GFAP and p75NTR markers showed that the content of ensheathing cells was maximum in passage 3 and 4 cultures (94 and 89.5%, respectively). The developed protocol can be recommended for obtaining autologous preparations of human ensheathing cells for cell therapy of spinal cord injuries.
