Abstract:
Provided is a preparation method for olfactory ensheathing cells. The method comprises the steps of formulation of a cell medium, collection and pretreatment of tissues, enzymatic digestion, cell culture, cryopreservation, and differentiation culture. The prepared olfactory ensheathing cells can maintain the proliferative capacity for a long time, and still possess the activity of olfactory ensheathing cells after 11 th  passage.

Claim (Index 1):
A preparation method for olfactory ensheathing cells, comprising the following steps:\n (1) culturing single olfactory ensheathing cells derived from the olfactory mucosa of upper and middle turbinate in an culture medium for olfactory ensheathing cells under the condition of 37\u00b0 C. and 5% CO 2 , and allowing the cells grow adherently; (2) mixing the cells obtained by filtering a culture supernatant obtained from step (1) with a culture medium for olfactory ensheathing cells again, culturing under the condition of 37\u00b0 C. and 5% CO 2 , and allowing the cells grow adherently.
