Embodiment Construction
[0015] The following in conjunction with specific embodiments is intended to further illustrate the present invention, rather than limit the present invention.
[0016] 1) Preparation of neural stem cell cryopreservation solution of the present invention:
[0017] 10ml neural stem cell cryopreservation solution contains the following components:
[0018]
[0019] Prepare the mother solution first, store it at -20 degrees, and then add it to the final concentration each time it is prepared.
[0020] 2) Cryopreservation of neural stem cells
[0021] Take the well-grown cells after 7-10 days of culture, and change the medium once 24 hours before collecting the cells. First use a pipette to blow gently in the primary culture bottle to float the cell balls that have settled at the bottom of the bottle. Then transfer the neurosphere suspension formed by the primary culture to a centrifuge tube, centrifuge at 800rpm / min for 3min. Discard the supernatant, and use the neural ste...
