The purpose of this clinical study is to answer the questions:
- Is the proposed intervention safe?
- Is the proposed intervention effective in improving the health of subjects with aging frailty?

Aging frailty is a clinical syndrome, characterized by a decrease of homeostatic reserves and enhanced vulnerability to endogenous or exogenous stressors, exposing individuals to an increased risk of adverse health-related outcomes. The human umbilical cord (HUC) is a promising source of mesenchymal stem cells (MSCs), compared to embryonic stem cells, HUC-MSCs are noncontroversial with a painless collection procedure and faster self-renewal properties. HUC-MSCs can differentiate into the different germ layers and modulate immune responses. One possible mechanism for the onset and development of aging frailty is the depletion of stem cells. Hence, intravenous infusion of HUC-MSCs is attractive therapy against aging frailty.
This is a randomized, multicenter,double-blind, placebo-controlled clinical trial. The participants from two centers (n = 30) will be randomly distributed into two groups. The HUC-MSCs Group (n = 15) will receive intravenous infusion of mesenchymal stem cells (80 Million) twice over a month (30 days interval), the Control Group (n = 15) will receive the same protocolized intervention with normal saline. Follow-up duration is 6 months after first intervention. The reported serious adverse events（SAEs）will be observed within one month post infusion. The short-item from health survey（SF-36), EuroQol five dimensions questionnaire (EQ-5D) and Fried phenotype scale will be evaluated. Short physical performance battery (SPPB) and plasm biomarkers will be assessed.The assessments will be performed at baseline, 3 months and 6 months.
The intent of this study is to explore domains of efficacy of HUC-MSCs through the reduction of signs and symptoms of aging frailty and to evaluate the safety of HUC-MSCs in subjects with aging frailty.

Experimental: HUC-MSCs Group
Human umbilical cord mesenchymal stem cells (80 Million cells/200ml): delivered via peripheral intravenous infusion.
Biological: Human umbilical cord mesenchymal stem cells（HUC-MSCs）
Human umbilical cord mesenchymal stem cells（HUC-MSCs）
Placebo Comparator: Control Group

- Safety of HUC-MSCs infusion [ Time Frame: Within one month post infusion ]
Safety were assessed by incidence of reported serious adverse events (SAEs) within one month after infusion. An SAE is defined as any untoward medical occurrence that:
- Results in death
- Is life-threatening (stroke or non-fatal pulmonary embolism, etc.)
- Requires inpatients hospitalization or prolongation of hospitalization
- Results in clinically significant abnormal laboratory test results or abnormal vital signs, based on clinical judgment.
- Difference in rate of decline of Frailty [ Time Frame: Baseline, 3 month and 6 months post infusion ]
Difference in rate of decline of Frailty assessed using Fried phenotype scale:
- Slowing of Mobility (assessed via a 4-meter gait speed test; Timed up and go (TUG) test and Short Physical Performance Battery (SPPB) assessment)
- Weight Loss (assessed via weighing scale)
- Reduced Activity (assessed via Minnesota Leisure Time Activities (MLTA) questionnaire)
- Diminished handgrip strength (assessed via dynamometer)
- Exhaustion (assessed by two items from the Center for Epidemiological Studies-Depression, CES-D):" I felt that everything I did was an effort? and I could not get going."
- Difference in subject quality of life assessments [ Time Frame: Baseline, month 3 and month 6 post infusion ]Health-related quality of life will be assessed with 3 subscales of Short-Form 36 Health Survey (SF-36), including physical functioning scale, mental health index and general health perception scale; the health status including Health State Index (HSI) and respondent's self-rated health on a vertical scale will be accessed via EuroQol 5-Dimension (ED-5D).
- Changes in the pro-inflammatory cytokines of blood sample between the HUC-MSC and placebo cohorts [ Time Frame: Baseline, month 3 and month 6 post infusion ]Enzyme-linked immunosorbent assay will be used to identify the serum levels of pro-inflammatory cytokines (e.g.,Interleukin-6).
- Changes in cellular components of the immune system between the HUC-MSC and placebo cohorts [ Time Frame: Baseline, month 3 and month 6 post infusion ]Flow cytometry will be used to identify the changes in numbers of lymphocyte subpopulations (e.g., B cells, T cells).
- Changes in Gut microbiota between the HUC-MSC and placebo cohorts [ Time Frame: Baseline, month 3 and month 6 post infusion ]The diversity and richness of gut microbiota at Phylum, Family and Species levels detected via next generation sequence
