Primary Outcome Measures:
- National Institutes of Health Stroke Scale [ Time Frame: 18 months, up to 36 months ]The change from the baseline in National Institutes of Health Stroke Scales
Secondary Outcome Measures:
- European Stroke Scale (ESS) [ Time Frame: 18 months, up to 36 months if applicable ]The change from baseline in ESS
- Barthel Index [ Time Frame: 18 months ]
- Min-Mental State Examination (MMSE) [ Time Frame: 18 months ]The change from baseline in MMSE
- MRI [ Time Frame: 18 months ]The change in MRI between pre-treatment and post-treatment
Other Outcome Measures:
- Safety as assessed by the incidence and severity of adverse events, clinically-significant changes in lab tests, vital signs, physical and neurological examinations. [ Time Frame: 18 months, up to 36 months follow-up ]Safety are assessed by the incidence and severity of adverse events, clinically-significant changes in lab tests, vital signs, physical and neurological examinations.

Detailed Description:
This is an open-label, delayed-treatment trial.
A total of 12 subjects fulfill the inclusion and exclusion criteria will be recruited and randomly assigned into two treatment group. Group A (early-treatment group) will receive transplant of UCBMC isolated from HLA-matched umbilical cord blood at Day 0. Group B (delayed-treatment group) will participate in 6 months observation before the UCBMC transplantation at Month 6. All subjects will be followed up for 18 months from enrollment at Day 0. Long-term follow-up will be carried up to 36 months if applicable.
The adverse events and safety parameters will be collected and recorded. In addition, the stroke scores , gait and brain MRI will be obtained before and after the treatment to assess the safety and potential treatment effect of UCBMC in chronic ischemic stroke.
