Fig. 3From: Neural stem/progenitor cells from adult canine cervical spinal cord have the potential to differentiate into neural lineage cellsGrowth characteristics and viability of neural stem/progenitor cells (NSPCs) (A) NSPCs were serially passaged in monolayer for five days until 80–90% confluency at each passage. The population-doubling level (PDL) was measured based on the average of the total number of three plate (60 mm PLO/fibronectin-coated petri dishes) cells in each passage. (B) Cell viability was measured based on the average viability of three plate cells in each passageBack to article page
