\[Inclusion Criteria\] 1. Subjects who show both upper motor neuron signs and lower motor neuron signs at the same time in neurological tests. 2. Among subjects diagnosed with familial or sporadic ALS, subjects falling into clinically definite ALS, probable ALS and probable ALS-lab supported according to The revised World Federation of Neurology El Escorial Criteria\[Rix Brooks, 2000\], during 17-weeks period prior to the administration and ALSFRS-R score (progression rate) of 1.03 ± 50%/month (meaning mean value in that total period). 3. For subjects who are under Riluzole treatment, those who have received stable dose of Riluzole for more than 28 days before screening visit. 4. Subjects with duration of disease of no more than 2 years from the first diagnosis date. 5. Subjects whose ALSFRS-R scores are in the range of 31\~46 at the time of screening (P-V0). \[Exclusion Criteria\] 1. Subjects who received tracheostomy or use ventilators (including positive pressure ventilators; subjects who use non-invasive ventilation for sleep apnea may be allowed after review) at the time of screening (P-V0). 2. Subjects who received gastrotomy at the time of screening (P-V0). 3. Subjects for whom clinical efficacy evaluation is not possible because pulmonary functional tests cannot be conducted at the time of screening (P-V0) or subjects whose forced vital capacity is found to be not greater than 40%of the expected value. 4. Subjects who fall into above Class II according to the New York Heart Association's functional classification, who have showed myocardial infarction, unstable arrhythmia and/or other significant cardiovascular diseases such as unstable angina in the past 3 months, or who show electrocardiographic signs of myocardial infarction or angina at the time of screening (P-V0) or who received stent insertion or coronary artery bypass grafting. 5. Subjects who have received other investigational products or edaravone within 3 month or 5 half-lives at the time of screening (P-V0) and lead in period visit L-V1 (evaluated by whichever is longer). 6. Subjects who have experienced epileptic seizure. 7. Subjects with severe renal disorder (serum creatinine: not less than 2.0 mg/dL). 8. Subjects with severe hepatic disorder (ALT, AST, or bilirubin: over 2.0 times of the normal upper limit). 9. Subjects who show hemorrhagic tendency at the time of screening (PT and aPTT \> 1.5 x ULN) 10. Subjects who are found to have active viral infections (HBsAg, HCV Ab, HIV Ab, CMV IgM, EBV IgM, HSV IgM and Treponema pallidum) at the time of screening. 11. Subjects with hypersensitivity to antibiotics (penicillin or streptomycin). 12. Subjects who have ever received any cell therapy product for the same disease. 13. Subjects with any malignant tumor in the past 5 years before screening, except malignant tumors with very low risk of metastasis or death.
