ating ▁them ▁according ▁to ▁their ▁type . ▁The ▁cells ▁are ▁label led ▁and ▁tag ged ▁to ▁identify ▁areas ▁of ▁interest ▁and ▁their ▁effect . ▁They ▁are ▁separated ▁based ▁on ▁differences ▁in ▁cell ▁size , ▁morph ology ▁( shape ), ▁and ▁surface ▁protein ▁expression . ▁The ▁resulting ▁hom olog ous ▁populations ▁of ▁cells ▁have ▁important ▁applications ▁in ▁research ▁and ▁as ▁th era pe ut ics . ▁ ▁Method s ▁▁ ▁There ▁are ▁three ▁major ▁methods ▁used ▁for ▁cell ▁sorting : ▁single ▁cell ▁sorting , ▁flu ores cent ▁activ ated ▁cell ▁sorting , ▁and ▁magnetic ▁activ ated ▁cell ▁sorting . ▁The ▁most ▁commonly ▁used ▁methods ▁are , ▁F AC S ▁( flu ores cent ▁activ ated ▁cell ▁sorting ) ▁and ▁MAC S ▁( mag net ic ▁activ ated ▁cell ▁sorting ). ▁These ▁methods ▁are ▁mostly ▁used ▁in ▁h emat ology , ▁c yt ogen et ics ▁and ▁stem ▁cell ▁research ▁labor ator ies . ▁Due ▁to ▁many ▁years ▁of ▁ref in ement ▁and ▁increased ▁demand ▁for ▁cell ular ▁analysis ▁however , ▁research ers ▁are ▁working ▁to ▁develop ▁micro fl uid ic ▁sorting ▁devices ▁that ▁have ▁many ▁benefits ▁in ▁comparison ▁to ▁traditional ▁F AC S ▁and ▁MAC S ▁devices , ▁but ▁are ▁seeing ▁many ▁bar riers ▁to ▁commercial ization . ▁ ▁Fl u ores cent ▁activ ated ▁▁ ▁Fl u ores cent ▁Activ ated ▁Cell ▁Sort ing , ▁or ▁F AC S , ▁util izes ▁flow ▁c yt ometry ▁to ▁provide ▁a ▁fast , ▁objective ▁and ▁quant itative ▁measurement ▁of ▁int ra - ▁and ▁ext rac
