Hine and laminin coated plates as talked about previously, (Basic Protocol three, step 2a). two hours later, the plates are ready to use. Thaw frozen 12 days neuron progenitors in water bath. Transfer all cells into 15 ml falcon tube containing 5 ml N2 medium. Spin down cells at 800 rpm for four min, wash once more with three ml N2 medium. Spin down cells at 800 rpm for four min. Aspirate supernatant, add two ml N2 medium plus B27 and ten M Rock inhibitor to resuspend cell pellet. Count and apply preferred variety of progenitor cells to each properly soon after aspirating laminin for further neuron differentiation.Author Manuscript Author Manuscript Author Manuscript Author Manuscript2. 3. four. 5.six.Reagents and Solutions The supplier info for all reagents and solutions under are supplied in Appendix Table 1 and Appendix Table 2.
