*Cells can be grown at 37C + 5% CO2,  and split 10-20X.  Typically healthy fibroblasts will repopulate in 2-3 days after a 10X dilution.
*Cells can be grown at 37C + 8% CO2,  and split 10-20X.  Typically healthy fibroblasts will repopulate in 2-3 days after a 10X dilution.
*Split cells when at about 80% confluence.  Confluence initiates the differentiation program, so if cells reach confluence, you will need to thaw another DMSO stock and start over.  Splitting cells will normally not reverse this

*When splitting cells, wash cells 2x with sterile PBS then add 0.05% trypsin and sit at room temperature for 2-5 min.  Be careful not to over-trypsinize cells
