the morphometric stereologic analysis shows that after 10 days of cold exposure the number of mitochondria per nucleus is nearly doubled ( from 1,912 to 3,414 ) , the total volume of the mitochondrial compartment per nucleus increases by about 40 % ( from 21 % to 29 % ) , and the mitochondrial membrane surfaces per nucleus increase too ( from 7,233 square microns to 11,597 square microns for the outer membranes ; from 31,572 square microns to 42,603 square microns for the inner membranes + cristae ) .
