Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Umbilical cord MSCs Group

Arm Description

1*10^7 Umbilical cord Mesenchymal Stem Cells (MSCs)

Outcomes

Primary Outcome Measures

Safety evaluation through vital signs, the results of clinical lab tests and adverse events
Safety evaluation through vital signs, the results of clinical lab tests and adverse events.

Secondary Outcome Measures

Number of participants with uterine niche
The niche is defined as a triangular anechoic area at the presumed site of incision in the uterus by transvaginal utrasonography.
Change of uterine scar thickness
The scar thickness be measured using a transvaginal utrasonography
Change of uterine scar area
The scar area will be measured using a transvaginal utrasonography
Number of participants with endometritis
Endometritis is defined as the presence of at least two of the following signs with no other recognized cause: fever (temperature of at least 38℃), abdominal pain, uterine tenderness, or purulent drainage from the uterus.
Number of participants with wound infection
Wound infection is defined as the presence of either superficial or deep incisional surgical-site infection characterized by cellulitis or erythema and induration around the incision or purulent discharge from the incision site with or without fever and included necrotizing fasciitis.
Immunoglobulin concentrations in breast milk and serum
Breast milk and serum immunoglobulin (IgG, IgA, IgM) and the complement (C3, C4) are detected by transmission immune turbidity method using automatic biochemical analyzer.
Adverse events occurrence
Adverse events will be evaluated since the baseline visit until 6 months after the end of the treatment.
