Table 3. Ergothioneine concentration in mouse cultured cortical NPCs exposed to ERGO (500 µM) for 6 and 9 days.

	Ergothioneine concentration (µg/g protein)^a)
NPCs (6DIV, (−) ERGO)	<61
NPCs (6DIV, (+)ERGO)	3572±629 [0.0016 mol/L]^b)
NPCs (9DIV, (−)ERGO)	<61
NPCs (9DIV, (+)ERGO)	10687±693^# [0.0047 mol/L]^b)

a) Concentration of ergothioneine was measured by LC-MS/MS.

b) The values shown in [ ] represent the mean values for intracellular concentration of ERGO estimated based on an assumption that cellular volume per g protein is 10 mL.

P<0.01, significant difference from the corresponding value at 6 DIV.
